在一行上打印隨機數組：Java

Question

正在構建一個可以在數組內部生成隨機整數值的數組。 它打印隨機數，但是像這樣打印它[10] [2] [5] [7] [6] [2] [4] [7] [2] [10] [0] --->（down側面）-------->，並希望它像這樣[10,7,5,9,4,3,4,7,2,3]（一行）打印。

   public class ArrayLab
{
    //array instance variable
    private int[] array1 = new int[10];

    //array constructor
    public ArrayLab(int integer)
    {
        //class parameter = 10
        int[] array1 = new int[]{integer};

    }

    public void initialize()
    {
         //allow randomization of numbers inside the array field.

        System.out.println(Arrays.toString(array1)); 
        //prints [0,0,0,0,0,0,0,0,0,0] which is ok

        System.out.println();
        for (int iteration = 0; iteration < array1.length; iteration ++)
        {
            Random number = new Random(); 
            number.nextInt(10);
            int n = number.nextInt(11);
            int[] array1 = new int[]{n};

            System.out.println(Arrays.toString(array1));
           //prints down the side. Want on one line?
        }

    }
}

Answer 1

只是改變

System.out.println(Arrays.toString(array1)); 
//new output
System.out.print(Arrays.toString(array1));

完成此操作的另一種方法是使用for循環以類似的方式遍歷數組

for( int i = 0; i < array1.length; i++ ){
    System.out.print(array1[i]+" ");
}

對於隨機數

Random ran = new Random();
for( int i = 0; i < array1.length; i++ ){
    int number = ran.nextInt((max - min) + 1) + min;
    //insert the maximum and min values for your generator
    array1[i] = number;
