        }

}

thanks to everyone that responed to my previous problem.Here in my displaytable method my if statments give me an error that say incompatable types required boolean found int.Any tips?

Use "==" to compare variables. "=" is used for assignment.

[Campbell Ritchie]

. . . and why are you using all those if blocks rather than

array[n]++

?

[Marcin Majewski]

You are not allowed to place assignments (=) in if statements. You are only allowed to make comparisons in if statements (==) and call methods that return boolean. This is a Java build-in security checking mechanism.

boolean test=false;
if(test=true) {
 System.out.println("Hi");
}

[Marcin Majewski]

Good point. Thanks.

. . . which is why using == true or == false is not only bad style, but potentially error-prone if you writey = instead of ==.
