怎么用java打印图形三： 1 7 12 16 19 21 2 8 13 17 20 3 9 14 18 4 10 15 5 11 6

public class E
public static void main(String[] args)
int k=1;
do
int i=k;
int j=6;
do
System.out.print(i+" ");
i=i+j;
j--;
while(j>=k);
System.out.println();
k++;
while(k<=6);


运行结果：
1 7 12 16 19 21
2 8 13 17 20
3 9 14 18
4 10 15
5 11
6 参考技术A public class Test
public static void main(String[] args)
int sum = 1;
for (int i = 6; i > 0; i--) // 输出6行
int num=6;
int n=sum;
for (int j = 1; j <= i; j++) //每行输出6-i个
System.out.print(n + "\t");
n=n+num;
num--;

sum++;
System.out.println();



参考技术B public class dome
public static void main(String[] args)
int sum = 1;
for (int a = 6; a > 0; a--) // 输出6行
int num=6;
int n=sum;
for (int i = 1; i <= a; i++) //每行输出6-i个
System.out.print(n + "\t");
n=n+num;
num--;

sum++;
System.out.println();
