returning a value from a method to another method

Question

Can somebody tell me why the value returned is 3 and not 8. Doesn\'t the return x statement from the addFive method change the value of x

Answer 1

The value in the main function is completely different from the value in the addFive(int x ) function. You send an x from main to addFive(int x) method.

JVM makes a copy of x and send it to addFive(int x) method. Then x changes in the addFive(int x) method. But the x in main() method remains unchanged.

If you want to get the changed value returned by addFive(int x) from main method you can do the following -

int returnedValueFromAddFive = addFive(x)  

Hope it will help.
Thanks a lot.
