如何在同一条水平线上显示不同的图案？

Question

我在 java 中设计了不同的模式，然后我希望所有模式都打印在一条水平线上。我的程序以垂直线显示输出。这是我的代码：

package demo;

public class PatternDemo {

  public static void main( String[] args ) throws InterruptedException {

    int n = 5;

    for ( int i = 0; i < n; i++ ) {

      for ( int j = 0; j < n; j++ ) {

        if ( i == 0 || j == 0 || i == n / 2 || (i <= n / 2 && j == n - 1)

            || i == n - 2 && j == n - 3 || i == n - 1 && j == n - 1 ) {

          System.out.print( "* " );

        } else {

          System.out.print( "  " );

        }

      }

      System.out.println( );

    }

    for ( int i = 0; i < n; i++ ) {

      for ( int j = 0; j < n; j++ ) {

        if ( i == 0 || j == 0 || j == n - 1 || i == n / 2 ) {

          System.out.print( "* " );

        } else {

          System.out.print( "  " );

        }

      }

      System.out.println( );

    }

  }

}

System.out.println() 将移动到下一行，移动后不能回到上一行。您必须更改整个逻辑才能获得所需的模式&nbsp; &nbsp; int n= 5;&nbsp; &nbsp; for ( int i = 0; i <n; i++) {&nbsp; &nbsp; &nbsp; &nbsp; for ( int j = 0; j <n; j++) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; if(i==0||j==0||i==n/2||(i<=n/2&&j==n-1)||i==n-2&&j==n-3||i==n-1&&j==n-1) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; System.out.print("* ");&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; } else {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; System.out.print("&nbsp; ");&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; &nbsp; &nbsp; for (int j = 0; j < n; j++) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; if(i==0||j==0||j==n-1||i==n/2){&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; System.out.print("* ");&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }else {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; System.out.print("&nbsp; ");&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; &nbsp; &nbsp; System.out.println();&nbsp; &nbsp; }输出：* * * * * * * * * *&nbsp;*&nbsp; &nbsp; &nbsp; &nbsp;* *&nbsp; &nbsp; &nbsp; &nbsp;*&nbsp;* * * * * * * * * *&nbsp;*&nbsp; &nbsp;*&nbsp; &nbsp; &nbsp;*&nbsp; &nbsp; &nbsp; &nbsp;*&nbsp;*&nbsp; &nbsp; &nbsp; &nbsp;* *&nbsp; &nbsp; &nbsp; &nbsp;*&nbsp;

System.out.print()将输出立即一个接一个地放置，它们之间没有换行符。这就是为什么某些部分出现在同一行中的原因。如果您希望它垂直打印，请使用System.out.println()，这将使下一行打印到下一行。
