Java Selenium questions for interview:

Why String is immutable in Java?

Assume you create a string variable str1, when this string is getting created inside the heap memory we have string pool, where your value will be stored as object. And then if you try to create a new string str2 with same value “RefreshScience”, str2 will get pointed to existing object. It won’t create another new object. JVM will check if the object exists, if it is not then it creates new object.

Example:
String str1 = “RefreshScience”; //object (101)
String str2 = “RefreshScience”; //object (101)
str1 points to object1, str2 also points to object1.

If any new value is assigned to str1, a new object will be created and the value of str2 still points to existing object.

Example:
str1 = “RefreshScience.com”; //object (103)

What is static in java?

Static keyword in java is used for memory management. We can declare method and variable as static.

Static method:
1. If a method is defined as static in java, it means we need not create any object to call that method. Method can be called directly, with the class name.
2. Static Method cannot call non static method directly.
3. Static Method cannot use non static variable.

Static Variable:
1. Static variable can be considered as global variable.
2. Memory for static variable gets assigned during class loading.

What is Static block In Java?

It’s a static block where we can have variables or statements which need to be executed before the main function.

What is final keyword in java?

Final Keyword in java is used to make the variable always constant. Value cannot be changed throughout the execution.

What is this keyword in java?

This keyword in java is used to refer the current object inside a method or a constructor. We might have same variable names inside a class, using ‘this’ keyword we can refer the current method’s variable.

What is finally and where do we use it?

Finally is used in Java exceptional handling when we use try/catch block. Finally block gets executed even if there is exception in code. Mostly finally block is used to clean the code post execution or closing the existing connections.
