これが私のクラスです。print() メソッドを取得して、配列の上に水平線を印刷し、配列の下に別の線を印刷しようとしています。また、配列内の各数値の間に垂直線を入れたいと思っています。さて、水平線を修正しました。今、配列の最初と最後に垂直線を配置する方法がわかりません。

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 ");
    }
}
}

System.out.println();各ダッシュ文字の後に新しい行を作成したくない場合は、行を for ループの外に移動します。

println()このループから抜け出します:

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