Decrement Operator

The operator -- is a postfix and a prefix decrement operator. The postfix operator decrements a variable after using its value; the prefix operator decrements a variable before using its value.

x++ use the value, then add 1int x = 10;
int y;
y = x++ ;
x is 11; y is 10
++x add 1, then use the valueint x = 10;
int y;
y = ++x ;
x is 11; y is 11
x-- use the value, then subtract 1int x = 10;
int y;
y = x-- ;
x is 9; y is 10
--x subtract 1, then use the valueint x = 10;
int y;
y = --x ;
x is 9; y is 9

Inspect the following code:

int x = 99;
int y = 10;

y = --x ;

System.out.println("x: " + x + "  y: " + y );
