Semantics of pre- and postfix “++” operator in Java [duplicate]

Answer 1

When we use post or pre increment operator it increases the value.

Post increment operator (i++) assigns the value first, then increments it. Pre increment operator (++i) increments first then assigns the value. They both behave like this :

int i=0;
i=i++;
System.out.println(i); //1
i=++i;
System.ou.println(i); //1
