二维数组该怎么遍历？

用两个for循环嵌套

public class Test03 {

	public static void main(String[] args) {
		int[][] arr = { { 23, 45, 65 }, { 12, 65, 1 }, { 83 }, { 12, 89, 1, 24 } };
		for (int i = 0; i < arr.length; i++) {
			for (int j = 0; j < arr[i].length; j++) {
				System.out.print(arr[i][j] + " ");
			}
			System.out.println();
		}
	}
