在方法内部修改数组参数

import java.util.Arrays;


public class Main {//来 自 n o w j a   v  a . c o m - 时  代  Java

  public static void main(String[] args) {

    int[] origNum = {1, 2, 3};

    System.out.println("Before method call:" + Arrays.toString(origNum));

    

    // Pass the array to the method

    tryArrayChange(origNum);

    

    System.out.println("After method call:" + Arrays.toString(origNum));

  }

  /** from 
  时代Java公众号 - nowjava.com**/

  public static void tryArrayChange(int[] num) {

    System.out.println("Inside method-1:" + Arrays.toString(num));


    // Create and store a new int array in num
