public class NineNine {
	public static void main(String[] args) {
		NineNine.nineNine();		
	}

	static void nineNine(){
		for (int i = 1; i < 10; i++){
			for (int j = 1; j <= i; j++){
				System.out.printf("%d*%d =%2d  ", i, j, i*j); //%2d表示i*j的结果占2个格
			}
			
			//换行
			System.out.println();
		}
	}
}

打印结果：

1*1 = 1  
2*1 = 2  2*2 = 4  
3*1 = 3  3*2 = 6  3*3 = 9  
4*1 = 4  4*2 = 8  4*3 =12  4*4 =16  
5*1 = 5  5*2 =10  5*3 =15  5*4 =20  5*5 =25  
6*1 = 6  6*2 =12  6*3 =18  6*4 =24  6*5 =30  6*6 =36  
7*1 = 7  7*2 =14  7*3 =21  7*4 =28  7*5 =35  7*6 =42  7*7 =49  
8*1 = 8  8*2 =16  8*3 =24  8*4 =32  8*5 =40  8*6 =48  8*7 =56  8*8 =64  
9*1 = 9  9*2 =18  9*3 =27  9*4 =36  9*5 =45  9*6 =54  9*7 =63  9*8 =72  9*9 =81
