% the modulus operator works with two variables or values

what i mean is
4%2==0;

As the modulus retrieves the remainder,
It must have.

for your program
if(j%i==0)
Your problem is solved!

You have tried to use the modulus operator without saying something on the other side of the %. I THINK you want 2 for this i.e. if(j%2==0), which tests to see if j is even.

EDIT: Also, use the bracket things ({ and }) when you are using if statements, 
if(j%==0){
System.out.println("o");
} else {
System.out.println("x");
}

EDIT 2 : You say  for(i=0;i>8;i++), which means that the program will never run as i is never greater than eight, the same for the other for loop. Change > for <.

The % operator only works between two integer values or two floating point values. You have nothing on the right-hand side of the % operator. Java doesn't know what you mean by this, so it refuses to compile it. For that matter, I don't know what you mean by it either.

Also, can you explain why you expect either of those for loops to run even once? The initial value in each case, 0, is already not greater than 8, so the conditions will never be satisfied.
