JAVA——数组反转

一、需求
首先创建一个长度是5的数组,并填充随机数。
二、实现代码

package demo;

public class TTT {
     
    public static void main(String[] args) {
     
        int[] a = new int[5];
        System.out.println("数组的随机数为：");
        for (int i = 0; i < 5; i++) {
     
            a[i] = (int) (Math.random() * 100);
            System.out.print(a[i]+" ");
        }
        
        for (int i = 0; i < a.length /2; i++) {
     
            int temp = a[i];
            a[i] = a[a.length - i - 1];
            a[a.length - i - 1] = temp;
        }
        System.out.println();
        System.out.println("-----Reversed Array------");
        for (int c: a ) {
     
            System.out.print(c+" ");
        
        }
    }
}
