Solve Error “int cannot be dereferenced” in Java

Dereferencing means accessing an object from the heap using a reference variable Or we can say It is a process of accessing the referred value by a reference. Dereferencing’s main purpose is to place the memory address (where the actual object presents) into the reference. Example:

Object ob = new Object();
String st = ob.toString(); // 'ob' is dereferenced.

1 2	Object ob = new Object(); String st = ob.toString(); // 'ob' is dereferenced.

If the reference has the null value, at that time the result of dereferencing will be a “Null Pointer Exception.” Example:

Object ob =null;
Ob.toString();  // when this statement is executed It will throw a NullpointerException.
