=> This is called “Call-by-Reference”, since you the reference to the non-primitive type is being set to the new variable instead of the plain value. Note the output of the program. The value of ‘a’ has been increased to 6, but the value of ‘x’ in the main method remains the same. This proves that the value is being copied to a different memory location in the call by value. Call by Reference. In the call by reference, both formal and actual parameters share the same value. Call by reference When a variable’s reference (address) and not its value is passed to a function’s parameter, any changes made to the parameter will update the original variable reference.

In call value actual value is copy to the method but In call by reference reference address of value is copy to the method. Difference between value type and reference type : There are following difference between value type and reference type on the basis of storage.
