# 0homework02最後一題，如果有更好想法可以分享，覺得弄得有點長

public class homework2_3 {

public static void main(String[] args) {
// TODO Auto-generated method stub
//輸出如題所示之資料圖形
int m;
int n;

for(m=1;m<=6;m++) {
for(n=1;n<=m;n++) {
switch(m) {
case 1:
System.out.print("A");
break;
case 2:
System.out.print("B");
break;
case 3:
System.out.print("C");
break;
case 4:
System.out.print("D");
break;
case 5:
System.out.print("E");

case 6:
System.out.print("F");

}

}
System.out.println();
