Call by Value and Call by Reference in Java
|There is only call by value in java, not call by reference. If we call a method passing a value, it is known as call by value. The changes being done in the called method, is not affected in the calling method.
Example of call by value in java
|In case of call by value original value is not changed. Let’s take a simple example:
Output:before change 50 after change 50
Another Example of call by value in java
In case of call by reference original value is changed if we made changes in the called method. If we pass object in place of any primitive value, original value will be changed. In this example we are passing object as a value. Let’s take a simple example:
Output:before change 50 after change 150
