The amount of memory space to be allocated for a variable is derived by modifiers. Modifiers are prefixed with basic data types to modify (either increase or decrease) the amount of storage space allocated to a variable. For example, storage space for int data type is 4 byte for 32 bit processor.
Is there pointers in Java?
A POINTER IS JUST THE ADDRESS OF SOME location in memory. In Java, pointers play an important role behind the scenes in the form of references to objects. A Java variable of object type stores a reference to an object, which is just a pointer giving the address of that object in memory.

Why are access modifiers important?
Access modifiers deal with the visibility of class members. They control whether other classes can see or change certain variables/methods of our class. These types of modifiers are closely related to an important part of Object Oriented Programming called encapsulation.
Why pointers are not used in Java?
Some reasons for Java does not support Pointers: Java has a robust security model and disallows pointer arithmetic for the same reason. … No pointer support make Java more secure because they point to memory location or used for memory management that loses the security as we use them directly.

Private: The private access modifier is specified using the keyword private. The methods or data members declared as private are accessible only within the class in which they are declared. Any other class of same package will not be able to access these members.
Is Final A access modifier in Java?
