Also do the following:

1.With example, explain the difference between reference and primitive variable.

2.________________ operator is used to create a class object

3.In a Java project, ClassA has methodA() .

Write the 2 lines of Java code that you would need in ClassB to create an object for ClassA to access its method methodA()

4. Write about any 2 methods that belong to String class

5. What does the following code do?

String str = "12345";
