You don't say what computer language you're using. It seems to be Java.

There may be other things wrong with the program, but mostly I notice that your first for loop sets "a>n" as its condition. Since a is initialized to 1 and n starts as 5, the loop will not even execute once.

There may be computer languages where the second term in a for loop statement is an until condition, but all of the ones I know use a while condition. You'd want to change it to a<=n.
