Question

如题所述

Answer 1

用for循环实现的菱形图形的Java程序如下：
public class Test {
public static void main(String[] args) {
final int N=4;
for (int i = 1; i <= N*2-1; i++) {
for (int j = 1; j <= Math.abs(N - i); j++) {
System.out.print(" ");
}
for (int k = 1; k <= 2*N-1-Math.abs(i-N)*2; k++) {
System.out.print("*");
}
System.out.println();
}
}
}

Answer 2

public static void main(String[] args) {
for(int i=1; i <=4; i++) {
for(int k=1;k<=2*i-1; k++) {
System.out.print("*");
}
System.out.print(" ");
}
for(int i=7; i >4; i--) {
for(int k=1;k<=2*(i-4)-1; k++) {
System.out.print("*");
}
System.out.print(" ");
}

}
