    Angry Need Help! For loops and if/else

    I don't see what is wrong i wrote it down on paper but here is the task i am trying to accomplish.

    Print out a count-by-count matrix of asterisks and percent signs, alternating by row
    Example:
    if count = 5
    output will be:

    * * * * *
    % % % % %
    * * * * *
    % % % % %
    * * * * *
    My Code:

    int t = 1;
    int k = 2;
    for(int i=1; i<=count; i++){ // how many sets of for j(5) COUNT IS USER INPUT but it is not in this code
    if(i == t){
    for(int j=1; j<=count; j++){ //how many asterisks get printed to a line(5)
    System.out.print(ast);
    t+=2; // prints on odd rows
    }
    }
    else if(i == k){ // checks when j is = to count(t)
    for(int l=1; l <= count; l++){
    System.out.print('%');
    k*=2; // prints only on even rows
    }
    }
    System.out.println();
    }

    All you need is 1 for loop and a conditional statement.

    for (index to count)
    if index is an odd number, print stars
    else print percentage
    end

    To determine if a number is even or odd, use the remainder operator (resources found here)
