这是一张java应用教程的随书光盘

public class ArrayOfArrays{
public static void main(String[] args) {
	int[][] a = new int[3][];
	for (int i = 0; i < a.length; i++) {
		a[i] = new int[i+2]; //创建一维数组的数组元素
		for (int j = 0; j < a[i].length; j++) {
			a[i][j] = i + j;
		}
	}
//打印
	for (int i = 0; i < a.length; i++) {
		for (int j = 0; j < a[i].length; j++) {
			System.out.print(a[i][j] + " ");
		}
	System.out.println();
	}
  }
