Nagarro Interview Questions and Answers
1. What is the life cycle of a bug?
Nagarro interview question life cycle of bug
In the software testing process, the bug or defect life cycle is the whole journey of a defect throughout its lifetime. It varies depending on the company and project. Its goal is to coordinate and communicate the present status of a problem, making the defect-fixing process efficient and systematic.
2. What does the word “data segment” in the programming language C mean?
A data segment is a part of a program’s virtual address space. It includes the static and global variables that the programmer initialized. The variables’ values can be changed during runtime since it is not read-only.
3. In Selenium, what is the distinction between frames and iframes?
A page is divided into several sections by Frame, and each section has new content. An iFrame embeds external websites’ content into the webpage. It assists in the avoidance of cross-site scripting issues.
4. Explain the V model.
A V model, also known as the Verification and Validation model, is an SDLC concept where sequentially running processes occur in a V-shape. A testing phase follows each development phase.
5. How does the merging sort work?
Merge sort is a divide-and-conquer algorithm that may be used to sort data. It merges and sorts nearby data to create huge sorted lists. These lists are then recursively combined to generate even larger sorted lists. The procedure is repeated until the programmer has one single sorted list.
6. Explain the concepts of inheritance and encapsulation.
Inheritance indicates that a child class takes all of the attributes/methods of a parent class and the winding of data into a single unit or class is known as encapsulation.
Nagarro Technical interview Questions
1. Explain the basics of PL/SQL.
The PL/SQL programming language is a procedural programming language that works on top of the SQL database. It has its syntax, but it may also be used in conjunction with SQL to access the complete range of database functions. Because it can do more complex tasks than SQL alone, PL/SQL is frequently used for business applications.
2. What exactly are data segments?
A data segment is a section of disc space allocated for the storage of user data. Disk space may be split into segments, which act as storage spaces for various types of data. Segments can be divided into three categories: physical, leachable, and non-leachable.
3. What is artificial intelligence?
Machines with artificial intelligence (AI) can act and think like people. A field of computer science called artificial intelligence (AI) focuses on building robots that can carry out activities that would typically need human intelligence. Automated planning, speech recognition, and translation are a few of the numerous possible applications of AI. For a long time, both the government and industry are using AI.
4. Write a program that returns true if every character in the string has the same frequency. Return false otherwise.
public boolean areOccurrencesEqual(String s) {
int max = 0;
char[] hash = new char[26];
//Counting the frequencies and determining the maximum frequency
for(int i = 0; i < s.length(); i++){
hash[s.charAt(i)-'a']++;
max = Math.max(max, hash[s.charAt(i)-'a']);
}
//Checking to see whether the frequency matches the maximum number
for(int i = 0; i < 26; i++){
if(hash[i] != 0 && hash[i] != max)
return false;
}
return true;
}
5. What are OOPs’ serialization and deserialization?
The process of transforming an object state into a format that can be sent or stored is known as serialization or marshaling. Data of the type Object is converted into data types like String, ByteArray, ArrayList, etc. using a serializer.
Deserialization on the other side is the opposite of serialization. It includes converting the object in the serialized data stream into the real instance of the class. When we require data again, deserialization is frequently utilized to get it from our storage systems.
6. Describe Cache Memory.
In a computer, cache memory serves similar functions as RAM. Data that is often accessed can be stored temporarily in cache memory. Application data, metadata, and result data can all be temporarily stored in cache memory, which is much faster than RAM.
Nagarro Java Interview Questions for Freshers
1. How does Java different from C++?
Java is both a compiled and an interpreted language, whereas C++ is simply a compiled language. A C++ program can only execute on the system in which it was compiled, but Java programs are machine-independent.
2. What makes Java a platform-independent language?
The Java language was designed in such a manner that it does not rely on any hardware or software since the compiler compiles the code and then transforms it to byte code that can be executed on a variety of systems.
3. Why aren’t pointers used in Java?
Beginner programmers should avoid using pointers since they are highly hard and risky. Java focuses on code simplicity, yet the use of pointers can make this difficult. The usage of pointers might potentially lead to errors. Furthermore, the usage of pointers compromises security since pointers allow users to directly access memory. Thus, not providing pointers in Java provides a certain amount of abstraction.
4. Give a more detailed definition of “local” and “instance” variables.
Local variables are variables that can only be accessed inside a block, constructor, or function. Only the block scope can be used with the variable. The class’s other methods are not aware of local variables that are declared inside of methods.
Instance variables are variables that are accessible by all of the class’s methods. They are declared outside of the methods as well as within the class. These variables describe the attributes of an object and are always connected to it.
5. When may you use a super keyword?
The super keyword can be used to access the parent class’s hidden fields and overridden methods or properties.
6. Describe the ClassLoader.
The JRE (Java Runtime Environment) is a program that belongs to Java Classloader. When necessary, ClassLoader loads the required classes and interfaces into the JVM.
7. In Java, what is the difference between shallow and deep copy?
We can say that we have performed a shallow copy when we divide an entity into two or more entities so that changes made to one entity are also reflected in the others.
We can say that we have performed a deep copy when we duplicate an entity to make two or more identical copies that do not reflect in the other entities.
Nagarro Java Interview Questions for Experienced
1. In Java, what is the difference between method overriding and method overloading?
Method overloading is used to improve program readability. Method overriding is used to offer the method’s custom implementation.
2. What exactly is an association?
An association is a partnership in which one party has no control over another. A person, for example, can be associated with various banks, and a bank can be associated with multiple persons, but no one can own the other.
3. What’s the distinction between JDK, JRE, and JVM?
JVM includes a Just in Time (JIT) compiler tool that changes all Java source code into low-level machine language. As a result, it operates faster than the default program.
Class libraries and other JVM-supporting resources are included in JRE. But it doesn’t have any Java development tools like a compiler or debugger.
The resources required to create Java applications are provided by JDK, which JRE subsequently uses to run them. It comes with a Java application launcher, a compiler, and an applet viewer.
4. In Java, how many different types of constructors are there?
In Java, constructors are classified into two categories.
Parameterized Constructors: The instance variables can be initialized by users using the parameters that the parameterized constructor allows. Users can dynamically initialize the class variables when they instantiate the class.
Default constructors: Instead of accepting any parameters, this type instantiates the class variables with their default values. It is mostly used for object creation.
5. What is Java’s session management?
The dynamic state of the client and server’s random conversation is essentially what is meant by the term “session.” A string of responses and requests from both sides is included in the virtual communication channel. The most popular technique for implementing session management is to create a session ID that is used in both the client and server’s communication.
6. Explain the various authentication methods in Java Servlets.
Servlets provide the following authentication methods:
- Basic Authentication: To authenticate the user, the client must give usernames and passwords.
- Form-based authentication: The programmer creates the login form using HTML.
- Client certificate authentication: Each client using the resource must have a certificate that it transmits to authenticate itself. Client authentication requires the SSL protocol.
- Digest Authentication: It works in the same way as basic authentication, except the passwords are encrypted using the Hash formula. Hash Formula improves digest security.
7. How can a string be reversed?
The following program can be used to reverse the string.
public class StringReverse {
public static void main(String args[]) {
String str = "";
String reverse = new StringBuffer(str).
reverse().
toString();
System. out.printf("Actua lWord: %s,Wordafterreversing%s", str, reverse);
}
public static String reverse(String source) {
if (source == null || source.isEmpty()) {
return source;
}
String reverse = "";
for (int i = source.length() - 1; i >= 0; i--)
{
reverse = reverse + source.charAt(i);
}
return reverse;
}
}
