Java编写四边形

1，正方形

private static void fun1() \{

Scanner sc = new Scanner(System.in);

System.out.println("请输入你要打的边长数：");

int a = sc.nextInt();

for (int i = 0; i < a; i++) \{//打印正方形的高

for (int j = 0; j < a; j++) \{//打印正方形的长

System.out.print("\*"+" ");

System.out.println(" ");

2，平行四边形

//平行四边形

private static void fun2() \{

Scanner sc = new Scanner(System.in);

System.out.println("请输入你要打的边长数：");

int a = sc.nextInt();

for (int i = 1; i <= a; i++) \{

for (int j = 1; j < i; j++) \{

System.out.print(" ");

for (int j = 1; j <= a; j++) \{

System.out.print("\*"+" ");

System.out.println(" ");

3，打印三角形

private static void fun3() \{

Scanner sc = new Scanner(System.in);

System.out.println("请输入你要打的边长数：");

int a = sc.nextInt();

for (int i = 1; i <= a; i++) \{

for (int j = 1; j <= a-i; j++) \{

System.out.print(" ");

for (int j = 1; j < i; j++) \{

System.out.print("\* ");

System.out.println();

4，打印菱形

private static void fun4() \{

Scanner sc = new Scanner(System.in);

System.out.println("请输入你要打的边长数：");

int a = sc.nextInt();

//上部分

for (int i = 1; i <= a; i++) \{

for (int j = 1; j <= a-i; j++) \{

System.out.print(" ");

for (int j = 1; j < i; j++) \{

System.out.print("\* ");

System.out.println();

//下部分

for (int i = 1; i <= a-1; i++) \{

for (int j = 1; j <=i; j++) \{

System.out.print(" ");

for (int j = 1; j

System.out.print("\* ");

System.out.println();

5，打印空心菱形

//空心菱形

private static void fun5() \{

Scanner sc = new Scanner(System.in);

System.out.println("请输入你要打的边长数：");

int a = sc.nextInt();

for (int i = 1; i <= a; i++) \{

for (int j = 1; j <= a-i; j++) \{

System.out.print(" ");

for (int j = 1; j <= i; j++) \{

if (j==1||j==i)\{

System.out.print("\* ");

\}else \{

System.out.print(" ");

System.out.println();

for (int i = 1; i <= a-1; i++) \{

for (int j = 1; j <=i; j++) \{

System.out.print(" ");

for (int j = 1; j <=a-i; j++) \{

if (j==1||j==a-i)\{

System.out.print("\* ");

\}else \{

System.out.print(" ");

System.out.println();
