Question

以下是我的java编程类中的一个作业。我已经编写了所有代码，但我无法想象如何使输出显示我需要它显示的内容。

对于我的任务，我必须编写一个带有一维数组的程序，该数组包含1到100之间的10个整数，并使用冒泡排序对数组进行排序。

输出需要的示例如下：

未分类列表为：54,27,13,97,5,63,78,34,47，和81
排序列表为：5,13,27,34,47,54,63,78,81，和97

我的输出显示：
未排序的列表是：54,27,13,97,5,63,78,34,47,81，
排序列表为：5,13,27,34,47,54,63,78,81,97，

我无法弄清楚如何将"and"写入输出。

public class Chpt7_Project {
/** The method for sorting the numbers */
public static void bubbleSort(int[] numbers) 
  {
    int temp;

      for (int i = numbers.length - 1; i > 0; i--) 
      {
         for (int j = 0; j < i; j++) 
         {
           if (numbers[j] > numbers[j + 1]) 
           {
           temp = numbers[j]; // swap number[i] with number[j]
           numbers[j] = numbers[j + 1];
           numbers[j + 1] = temp;
           }
         }
      }
   }
public static void main(String[] args) { // Test Method

    System.out.print("The unsorted list is: ");
    // Generate 10 random numbers between 1 and 100
    int[] numbers = new int[10]; 

    for (int i=0;i<numbers.length;i++) {
        numbers[i] = (int) (Math.random() * 100); 
        System.out.print(numbers[i] + ", ");
    }
    System.out.println();

    bubbleSort (numbers); // numbers are sorted from smallest to largest
    System.out.print("The sorted list is: ");
    for (int i=0;i<numbers.length;i++) {
        System.out.print(numbers[i] + ", ");
    }
}


}

Answer 1

更改此循环

for (int i=0;i<numbers.length;i++) {
    System.out.print(numbers[i] + ", ");
}

到

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

Answer 2

输出：

The unsorted list is: 67, 86, 78, 80, 56, 45, 24, 2, 67, and 98

The sorted list is: 2, 24, 45, 56, 67, 67, 78, 80, 86, and 98

修改后的代码（@abhinav提到的集成内容）：

public class Chpt7_Project {
/** The method for sorting the numbers */
    public static void bubbleSort(int[] numbers) {
        int temp;
        for (int i = numbers.length - 1; i > 0; i--) {
            for (int j = 0; j < i; j++) {
                if (numbers[j] > numbers[j + 1]) {
                   temp = numbers[j]; // swap number[i] with number[j]
                   numbers[j] = numbers[j + 1];
                   numbers[j + 1] = temp;
               }
             }
          }
       }

    public static void main(String[] args) { // Test Method

        System.out.print("The unsorted list is: ");
        // Generate 10 random numbers between 1 and 100
        int[] numbers = new int[10]; 
        for (int i=0;i<numbers.length;i++) {
            numbers[i] = (int) (Math.random() * 100);
            if(i== numbers.length-1) {
                System.out.println("and "+numbers[i]);
            } else {
                System.out.print(numbers[i] + ", ");
            }
        }
        System.out.println();
        bubbleSort (numbers); // numbers are sorted from smallest to largest
        System.out.print("The sorted list is: ");
        for (int i=0;i<numbers.length;i++) {
            if(i== numbers.length-1) {
                System.out.println("and "+numbers[i]);
            } else {
                System.out.print(numbers[i] + ", ");
            }
        }
    }
}

在最后一个元素之前用“和”打印int数组
