Increment a Integer's int value?

Question

How do I increment a Integer\'s value in Java? I know I can get the value with intValue, and I can set it with new Integer(int i).

playerID.intValue()++;


        

Answer 1

For Java 7, increment operator '++' works on Integers. Below is a tested example

    Integer i = new Integer( 12 );
    System.out.println(i); //12
    i = i++;
    System.out.println(i); //13

Answer 2

Maybe you can try:

final AtomicInteger i = new AtomicInteger(0);
i.set(1);
i.get();

Answer 3

You can use IntHolder as mutable alternative to Integer. But does it worth?
