Here is my code:

Code:

public class Banie {

private final int height;

private final int width;

public Banie(final int height, final int width) { // Constructor
this.height = height;
this.width = width;
}

public void print() {
for (int line = 0; line < height; line++) {
final double percentage = line / (double) height;
final int item = (int) (percentage * width) + 1;  // Type casting
for (int at = 0; at < item; at++) {

System.out.print("@");
}

System.out.println();
if ( height == item);
}

}

public static void main(String[] args) {
Banie t = new Banie(7, 7); // Parsing args
t.print(); // Calling method
}
}

Hello banie

I indented and tested your code and it looks file:

Code:

public class Banie {
	private final int height;
	private final int width;

	public Banie(final int height, final int width) { // Constructor
		this.height = height;
		this.width = width;
	}

	public void print() {
		for (int line = 0; line < height; line++) {
			final double percentage = line / (double) height;
			final int item = (int) (percentage * width) + 1;  // Type casting
			for (int at = 0; at < item; at++) {
				System.out.print("@");
			}
			System.out.println();
			if ( height == item);
		}
	}
}

It gives output

Is this what you wanted? Or, do you need:

banie, this topic was discussed recently... you may wish to use the search feature next time. When you use the search, compare your code to the code you find from others. This helps to strengthen your coding "eyes" and reasoning ability/logic skills.

So what exactly is the problem? tim provided you with an easy solution, now just add that extra line in and you've got that output.
