Printing a shape based on inputs from the user

I am trying to print a shape based on input; the shape is an "x". The inputs must be positive odd ints, and an arbitrary brush character. I have the code completed for the user input, but I need help with the code that actually prints the shape. Here is what I have so far:

Code starts here for (int row = 0; row < height/2; row++) { for (int i = row; i > 0; i--) { System.out.print(" "); }

    System.out.print(brush); 
    for (int i = (height/2); i >= 2*row; i--) {
        System.out.print(" "); 
    }

    System.out.print(brush);
    System.out.print("\n");

}

for (int row = 1; row < (height/2)+1; row++ ) {
    System.out.print(" "); 
}
System.out.print(brush);
System.out.print("\n"); 
for (int row = (height/2)-1; row >= 0; row--) {
    for (int i = row; i > 0; i--) {
        System.out.print(" ");
    }

    System.out.print(brush); 
    for (int i = (height/2); i >= 2*row; i--) {
        System.out.print(" "); 
    }

    System.out.print(brush);
    System.out.print("\n");

}

for (int row = 1; row < (height/2)+1; row++ ) {
    System.out.print(" ");
