生成一个随机数据

import java.util.Random;
public class  RandomNumber{    
    public static void main (String args[]) {       
        Random rnd = new Random();               
        
        int intnums[] = new int[25];           
        for (int i=1; i<25; i++) {       
             intnums[i] = rnd.nextInt(25);      
                    }            
        for (int i=0; i<25; i++) {      
                  System.out.print(intnums[i] + " ");                   
                  if (i % 5 == 4)                      
            System.out.println();           
                  }    
        }
    }
