Top  190+ Java Interview Questions for Freshers

Let’s discuss some common advanced Java interview questions for beginners.

1. What is Java?

It is an object programming language designed for portability across platforms and operating systems. Sun Microsystems produced this language.

2. Explain Java's history

Java was created by James Gosling at Sun Microsystems (now Oracle) in the early 1990s. Java was supposed to be "write once, run anywhere."

3. Define Static Java

Each class has one static, not one for every object, regardless of class instances. They can be used without constructing a class instance.

4. What Makes Java Platform Independent?

Since platform-independent means write once run anywhere. Java is named for its bytecodes regardless of its operating system.

5. Why are generics used in Java?

In Java, generics provide compile-time safety to identify improper types. Developers can declare one method or a series of methods.

6. Explain Java constructors

A Java constructor initializes an object when it is created. When it is created using the new keyword, it immediately establishes its initial state.
