感觉我没对齐,就是实现左边的那位对齐!

Answer 1

public static void main(String[] args) {
// TODO Auto-generated method stub
for (int j = 1; j <= 5; j++) {
for (int i = 1; i <= 5; i++) {
System.out.print("\t"+j*i); // \t可以对其
}
System.out.println();
}

}

Answer 2

int k=0;
for(int i=1;i<6;i++){
for(int j=1;j<6;j++){
D[i][j]=k;
k++;
System.out.format("%4d", D[i][j]);
}
System.out.println();
}

Answer 3

public static void main(String[] args) {
// TODO Auto-generated method stub
for (int j = 1; j <= 5; j++) {
for (int i = 1; i <= 5; i++) {
System.out.print(j*i);
}
System.out.println();
}

}
