Make a rhombus using Java

public class ex3 {
	public static void main(String[] args) {
		int i, j;
		int max = 5;
		int p = max / 2 + 1;
		int left = p;
		int right = p;

		for (i = 1; i <= max; i++) {
			for (j = 1; j <= max; j++) {
				if (j >= left && j <= right) {
					System.out.print("*");
				} else {
					System.out.print(" ");
				}
			}
			System.out.println();
			if (i < p) {
				left--;
				right++;
			} else {
				left++;
				right--;
			}
		}
	}
