When would you use postfix vs the prefix ? Please show an example?

When you want something incremented/decremented before you use the variable, you must use prefixed operator, otherwise the variable will be used first and icremented after: e.g. var i = 0; var j = 0; document.write(++i); document.write(j++); The values printed will be respectively 1 and 0. The use of each other will vary accordingly with your necessity.

in simple way Suppose u have any variable like Int a=10; and u want to use it start with 11 then u need preIncrement... it increments the value first then exicute.. int a =10; system.out.println(++a); output = 11
