java - 多行打印数组

Question

我正在参加编程类(class)，但事情并不适合我。我有一项作业要求:

Write a program to assign the integer values 1 through 25 to a 25 element integer array. Then, print the array as five separate lines each containing five elements separated by commas. The last element on each line should be followed by a newline instead of a comma. The output of your program should appear exactly as follows:

1,2,3,4,5

6,7,8,9,10

11,12,13,14,15

16,17,18,19,20

21,22,23,24,25

Hints:

• One way to determine every 5th element is to use the modules operator (%). If you divide the subscript by 5 and the remainder is 0, it is the 5th number.
• You can use System.out.print() to print a value without a newline following it. This will allow you to print multiple things on the same line.

我有一些代码，但我不知道从这里去哪里:

public class Program4

{

     public static int[] array;

     public static void main(String[] args);

     {

          int[] numbers = new int [25]

          for(int i=0; i<25; i++)

                array[i] = i + 1;}

     public static void printArray()

     {

          for(int i=1; i<=25; i++);

          {

               System.out.print(array[i - 1]);

               if (i % 5 == 0)

                    System.out.printIn();

           }

     }

我只是对编程有一个心理障碍 - 谁能帮我指出一些有用的例子？

试试这个，

import java.util.*;
import java.lang.*;
import java.io.*;

/* Name of the class has to be "Main" only if the class is public. */
class Ideone
{
     public static int[] array;

     public static void main(String[] args)
     {
        array = new int[25];
        for(int i=0; i<25; i++)
           array[i] = i + 1;   
        printArray();
     }

     public static void printArray()

     {
        int i;
        for(i=1; i<=25; i++){
            if (i % 5 != 0)
                System.out.print(array[i-1]+",");
            else
                System.out.println(array[i-1]);
       }
     }
}
