Compare whether the two arrays are the same

demand ：

If the types of two arrays , Element number , The order and content of elements are the same, so we think this is the case 2 An array is as like as two peas. .
Please use the method to complete ： Can determine whether any two integer arrays are the same , And back to true perhaps false.

analysis

1、 Define methods , receive 2 An integer array ,—> Whether parameters are required 、 return type ？
2、 Complete the logic of judgment inside the method , And return Boolean results .

Code

package com.xxf.create;

public class MethodDemo6 {
    
    public static void main(String[] args) {
    
        // demand ： Compare the contents of any two integer arrays , Just go back to true, Otherwise return to false
        int[] arr1 = {
    11, 22, 33, 44};
        int[] arr2 = {
    11, 22, 33, 44};
        System.out.println(compare(arr1, arr2));
    }

    //1、 Define a method , Parameters , Receive two shaping data , return type ： Boolean type 
    public static boolean compare(int[] arr1, int[] arr2) {
    
        //2、 Determine whether the contents of the two arrays are consistent 
        if (arr1.length == arr2.length) {
    
            for (int i = 0; i < arr1.length; i++) {
    
                if (arr1[i] != arr2[i]) {
    
                    return false;
                }
            }
            return true;
        } else {
    
            return false;
        }

    }
