如何反向打印数组？ [英] How can I print an array in reverse?

问题描述

这是我的数组代码，我需要反向打印。

  public class Array1D {
 public static void main（String [] args）{
 int [] array = new int [3]; 
 array [0] = 1; 
 array [1] = 2; 
 array [2] = 5; （int i = 0; i  System.out.print（array [+ i +] =）; 
 System.out.println（array [i] +）; 
} 
 System.out.println（matrix中的最后一个元素=+ array [array.length  -  1]）; //找到数组中的最后一个元素
 System.out.println（）; 
} 
} 
  

解决方案

反转您的for循环的方向。现在它是从0到长度，从长度到零计数$（$ i pre pre pre pre $ length-1; i> = 0; i--）

This is my array code and I need to print it in reverse.

public class Array1D {
    public static void main(String[] args) {
        int[] array = new int[3];
        array[0] = 1;
        array[1] = 2;
        array[2] = 5;
        for (int i = 0; i < array.length; i++) { //loop
            System.out.print("array["+i+"]=");
            System.out.println(array[i] + "   ");
        }
        System.out.println("the last element in the matrix = " + array[array.length - 1]); // finding the last element in the array
        System.out.println("   ");
    }
}

解决方案

Just reverse the direction of your for loop. Right now it is counting from 0 to the length, have it count from the length to zero

for (int i = array.length-1; i >= 0; i--)
