如何用 for 循环生成水平线和垂直线？

Question

所以这是我的 class。我正在尝试使用 print() 方法打印出数组上方的水平线和数组下方的另一条线。我还希望在我的数组中的每个数字之间有垂直线。好的，我修正了我的水平线。现在我不知道如何在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：

Original:
-----------
1|5|9|3|3
-----------
Sorted:
-----------
1|3|3|5|9
-----------
Frequencies:
There are 0, 0's 
There are 1, 1's 
There are 0, 2's 
There are 2, 3's 
There are 0, 4's 
There are 1, 5's 
There are 0, 6's 
There are 0, 7's 
There are 0, 8's 
There are 1, 9's

There are 1, 5's 
There are 0, 6's 
There are 3, 7's 
There are 1, 8's 
There are 0, 9's

我的输出应该是这样的：

There are 0, 0's

There are 0, 7's
There are 0, 8's
There are 1, 9's

Answer 1

如果您不想在每个破折号字符后创建一个新行，请将行 System.out.println(); 移到 for 循环之外。

Answer 2

将 println() 移出此循环：

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