forループを使って水平線と垂直線を作成する方法は？

Question

これは私のクラスです。私はprint（）メソッドを取得して、配列の上に水平線を、配列の下に別の線を印刷しようとしています。私はまた、配列内の各数値の間に垂直線を持っていたい。さて、私は水平線を固定しました。今では、配列の始めと終わりに縦線をどのように置くのかが分かりません。

public class Array{ 

private int[] array; 

public Array(int numElements) 
{ 
    array = new int[numElements]; 
} 

public void fill() 
{ 
    for (int i = 0; i < array.length; i++) 
    { 
     array[i] = (int) (10*Math.random()); 
    } 
} 

public void print() 
{ 
    for(int x = 0; x < 2*array.length; x++) 
    { 
     System.out.print("-"); 
    } 
    System.out.println(); 

    for(int i = 0; i < array.length; i++) 
    { 
     System.out.print(array[i]); 
     if(i == array.length - 1) 
     { 
      System.out.println(); 
     } 
     else 
     { 
      System.out.print("|"); 
     } 
    } 

    for(int n = 0; n < 2*array.length; n++) 
    { 
     System.out.print("-"); 

    } 
    System.out.println(); 
} 

public void sort() 
{ 
    int n = array.length; 
    boolean swapped; 

    do 
    { 
     swapped = false; 

     for(int i = 1; i < n; i++) 
     { 
      if(array[i-1] > array[i]) 
      { 
       int tmp = array[i]; 
       array[i] = array[i-1]; 
       array[i-1] = tmp; 
       swapped = true; 
      } 
     } 
    } while(swapped); 
} 

public void printFrequency() 
{ 
    int[] countArray = new int[10]; 
    for(int x : array) 
    { 
     countArray[x]++; 
    } 
    for(int i = 0; i < 10; i++) 
    { 
     System.out.println("There are " + countArray[i] + ", " + i + "'s "); 
    } 
} 
}

Answer 1

は、あなたのforループのラインSystem.out.println();外を移動します各ダッシュ文字の後に新しい行。

Answer 2

は、このループの外にprintln()を取る：

for(int n = 0; n < array.length; n++) 
{ 
    System.out.print("-"); 
    System.out.println(); 
}
