法律Java 程序打印方形星形图案
在本文中，我们将了解如何打印方形星形图案。该图案由多个 for 循环 和打印语句构成。
以下是相同的演示 −
输入
假设我们的输入是 −
Enter the length of a side : 8
输出
期望的输出为 −
The square pattern : * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
算法
Step 1 - START Step 2 - Declare three integer values namely i, j and my_input Step 3 - Read the required values from the user/ define the values Step 4 - We iterate through two nested 'for' loops to get space between the characters. Step 5 - After iterating through the innermost loop, we iterate through another 'for' loop. This will help print the required character. Step 6 - Now, print a newline to get the specific number of characters in the subsequent lines. Step 7 - Display the result Step 8 - Stop
示例 1
在此，输入由用户根据 8a 提示输入。你可以在我们的 编码平台工具 
中在线运行此示例。
import java.util.Scanner;
public class SquarePattern{
public static void main(String args[]){
int i, j, my_input;
System.out.println("Required packages have been imported");
Scanner my_scanner = new Scanner(System.in);
System.out.println("A reader object has been defined ");
System.out.print("Enter the length of a side : ");
my_input = my_scanner.nextInt();
System.out.println("The square pattern : ");
for(i = 1; i <= my_input; i++){
for(j = 1; j <= my_input; j++){
System.out.print("*");
}
System.out.print("\n");
}
}
}输出
Required packages have been imported A reader object has been defined Enter the length of a side : 8 The square pattern : * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
示例 2
此处，整数已经事先定义，在控制台中访问并显示其值。
public class SquarePattern{
public static void main(String args[]){
int i, j, my_input;
my_input = 8;
System.out.println("The length of a side is defined as " +my_input);
System.out.println("The square pattern : ");
for(i = 1; i <= my_input; i++){
for(j = 1; j <= my_input; j++){
System.out.print("* ");
}
System.out.print("\n");
}
}
}输出
The length of a side is defined as 8 The square pattern : * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
