Question

Is there any difference between x++ and ++x in Java?

Answer 1

We call x++ as postincrement and ++x as preincrement.

In x++ the variable value is used first in the expression and then it is incremented after the operation.

In ++x the variable is incremented and then uses the new value in the expression. 

Here is an example that will explain about them:

int x = 5, y = 5;

System.out.println(++x); // outputs 6

System.out.println(x); // outputs 6

System.out.println(y++); // outputs 5

System.out.println(y); // outputs 6
