java 怎样写出一个菱形程序？空心和实心
java打印菱形通过二维数组来打印，实例如下：
int hangshu = 11;
int yiban = hangshu / 2 + 1;
int yibanduo = hangshu / 2;
System.out.println("空心菱形：");
for(int k = 1;k = yiban;k++){
for(int i = 1;i = (yiban - k);i++){
System.out.print(" ");
}
System.out.print("*");
for(int i = 1;i = ( (k - 2) * 2 + 1);i++){
System.out.print(" ");
}
if(k != 1){
System.out.print("*");
}
System.out.println();
}
for(int k = yibanduo;k =1;k--){
for(int i = 1;i = (yiban - k);i++){
System.out.print(" ");
}
System.out.print("*");
for(int i = 1;i = ( (k - 2) * 2 + 1);i++){
System.out.print(" ");
}
if(k != 1){
System.out.print("*");
}
System.out.println();
}
System.out.println("实心菱形：");
for(int i = 1;i = hangshu;i++){
if(i = hangshu/2 + 1){
for(int k = 1;k = hangshu/2 + 1- i;k++){
System.out.print(" ");
}
for(int k = 1;k = i;k++){
System.out.print("* ");
}
System.out.println();
}else{
for(int k =1;k = (i -(hangshu/2 + 1));k++){
System.out.print(" ");
}
for(int k = 1;k = (2 *(hangshu/2 + 1) - i);k++){
System.out.print("* ");
}
System.out.println();
}
}
结果如下：

Q1: java打印空心菱形
Java利用for循环输出空心菱形java打印镂空菱形代码的实例代码
编写程序java打印镂空菱形代码，在控制台上输出空心菱形java打印镂空菱形代码，对角距离为6.
代码如下：
public class Diamond {
public static void main(String[] args) {
printHollowRhombus(6);
}
public static void printHollowRhombus(int size) {
if (size % 2 == 0) {
size++;// 计算菱形大小
}
for (int i = 0; i size / 2 + 1; i++) {
for (int j = size / 2 + 1; j i + 1; j--) {
System.out.print(" ");// 输出左上角位置的空白
}
for (int j = 0; j 2 * i + 1; j++) {
if (j == 0 || j == 2 * i) {
System.out.print("* ");// 输出菱形上半部边缘
} else {
System.out.print(" ");// 输出菱形上半部空心
}
}
System.out.println(""); //换行
}
for (int i = size / 2 + 1; i size; i++) {
for (int j = 0; j i - size / 2; j++) {
System.out.print(" ");// 输出菱形左下角空白
}
for (int j = 0; j 2 * size - 1 - 2 * i; j++) {
if (j == 0 || j == 2 * (size - i - 1)) {
System.out.print("* ");// 输出菱形下半部边缘
} else {
System.out.print(" ");// 输出菱形下半部空心
}
}
System.out.println(""); //换行
}
}
}
效果如图：
Q2: 怎么用java打印菱形？
java打印菱形方法：
package circulationDemo;
import java.util.Scanner;
public class Test {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.println("请输入要打印的行数：");
int num = input.nextInt();
t1(num);// 正直角
split();
t2(num);// 倒直角
split();
t3(num);// 等腰三角
split();
t4(num);// 等腰倒三角++
split();
t5(num);// 等腰倒三角--
split();
t6(num);// 实心菱形
split();
t7(num);// 空心菱形(1)
split();
t8(num);// 空心菱形(2)
split();
t9(num);// 空心菱形(3)
}
private static void t9(int num) {
for (int k = 1; k = num; k++) {
