Question

我是Java的新手，在打印两个独立的阵列时遇到问题。我定义了一个长度为3的int数组和一个长度相同的第二个数组，它由第一个数组除以数字19的余数填充。第一个数组存储随机生成的值。这是我的代码：

import java.util.Random;

public class Hashing {

    public static void main(String[] args) {
        int[] array = new int[3];

        Random generator = new Random();
        for (int i = 0; i < array.length; i++) {
            array[i] = generator.nextInt(80);

            int[] newarray = new int[3];

            for (int j = 0; j < newarray.length; j++) {
                newarray[j] = array[i] % 19;

                System.out.println("array= " + array[i]);

                System.out.println("residuals=" + array[j]);
                System.out.println("\n");

            }

        }
    }
}

此代码有问题。我想要的是这个;

array[0]
array[1]
array[2]

然后

residuals[0]
residuals[1]
residuals[2]

但结果如下：

array[0]
residuals[0]
array[1]
residuals[1]
array[2]
residuals[2]

我该怎么纠正这个？我尝试通过进行以下修改来纠正打印

   import java.util.Random;

    public class Hashing {

        public static void main(String[] args) {
            int[] array = new int[2];
            Random generator = new Random();
            for (int i = 0; i < array.length; i++) {
                array[i] = generator.nextInt(80);

                    System.out.println("array= " + array[i]);
                    System.out.println("\n");

                }

                int[] newarray = new int[2];enter code here

                for (int j = 0; j < newarray.length; j++) {


               newarray[j] = array[i] % 19;

                    System.out.println("residuals=" + array[j]);
                    System.out.println("\n");

            }
        }
    }

但这次我在这部分中遇到错误：

newarray[j] = array[i] % 19;

它说它无法解析为变量。然而，它已经在上面的循环中定义:(有人可以帮我一把吗？谢谢

Answer 1

打印一个数组，然后打印另一个

for (int j = 0; j < newarray.length; j++) {
    newarray[j] = array[i] % 19;
    System.out.println("array= " + array[i]);
    System.out.println("\n");
}

for (int j = 0; j < newarray.length; j++) {
    System.out.println("residuals=" + array[j]);
    System.out.println("\n");
}

Answer 2

import java.util.Random;

public class Hashing {

    public static void main(String[] args) {
        int[] array = new int[3];
        Random generator = new Random();
        for (int i = 0; i < array.length; i++) {
            array[i] = generator.nextInt(80);

                System.out.println("array= " + array[i]);

       }
            System.out.print("\n");
            int[] newarray = new int[3];

            for (int j = 0; j < newarray.length; j++) {


           newarray[j] = array[j] % 19;

           System.out.println("residuals=" + newarray[j]);

        }
    }
}

Answer 3

请尝试以下代码：

import java.util.Random;

public class Hashing {

    public static void main(String[] args) {
        int[] array = new int[3];

        Random generator = new Random();

        for (int i = 0; i < array.length; i++) {
            array[i] = generator.nextInt(80);

            int[] newarray = new int[3];

            newarray[i] = array[i] % 19;
            for (int j = 0; j < newarray.length; j++) {
                System.out.println("array= " + array[i]);
            }
            System.out.println("");

            for (int j = 0; j < newarray.length; j++) {
                System.out.println("residuals=" + array[j]);

            }
            System.out.println("");

        }
    }
}

我希望这就是你要找的东西。
