Array as a parameter:

package com.wys.java;

import java.security.PublicKey;

//数组作为函数参数
public class functionDemo {
    public static void main(String[] args) {
        int[] arr0 = {1,2,3,4,5};
        printArray(arr0);
    }

    public static void printArray(int[] arr1){
        for(int i=0; i<arr1.length; i++){
            System.out.print(arr1[i]+" ");
        }
        System.out.println();
    }
}

result:

 

 

 

Array as a return value:

Package com.wys.java; 

// array as the function return value 
public  class returnDemo {
     public  static  void main (String [] args) {
         int [] = {1,2,3,4,5 arr0 }; 

        the System.out. the println ( "source array:" ); 
        printArray (arr0);    // prints the original array 

        int [] = arrReverse reverseArray (arr0);   // get an array of oppositely oriented 

        System.out.println ( "Invert the array:" ); 
        printArray (arrReverse);      // Print results array 
    } 

    // get new array is sorted to the reverse of the array of 
    public  static  int[] ReverseArray ( int [] arr1Temp) {
         int [] = resultArray new new  int [arr1Temp.length];    // Create the result array as a return value 
        for ( int I = 0; I <resultArray.length; I ++ ) { 
            resultArray [I ] arr1Temp.length = arr1Temp-l- [ I]; 
        } 
        return resultArray; 
    } 

    // print element array 
    public  static  void printArray ( int [] arrTemp) {
         for ( int element: arrTemp) { 
            of System.out.print (element + "" ); 
        }
        System.out.println();
    }
}

result:
