所以这是我的课。我试图让 print() 方法在我的数组上方打印出一条水平线，在我的数组下方打印出另一条线。我还想在我的数组中的每个数字之间有垂直线。好的，我修复了我的水平线。现在我只是迷失了如何在我的数组的开头和结尾放置垂直线。

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 ");
    }
}
}

这是我的输出：

1|5|9|3|3

1|3|3|5|9

There are 0, 0's

There are 1, 5's 
There are 0, 6's 
There are 3, 7's

System.out.println();如果您不想在每个破折号字符后创建新行，请将行移到 for 循环之外。

摆脱println()这个循环：

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