Up counter and down counter programs in java?

Answer 1

You can increase a counter variable - or any variable for that matter - with the ++ or += operators.

Examples:

// Increase one at a time
for (int i = 1; i <= 10; i++) System.out.println(i);

// Increase two at a time
for (int i = 2; i <= 10; i+=2) System.out.println(i);

// Decrease one at a time
for (int i = 10; i >= 1; i--) System.out.println(i);

// Decrease two at a time
for (int i = 10; i >= 2; i-=2) System.out.println(i);

You could come along without the "++" and "--" operators, but since incrementing or decrementing one at a time is a fairly common situation, a special operator was introduced, as a shortcut.
