数组输出有问题，但是找不到问题在哪，希望能看一看，就是合并两个数组

你输出的都是数组的地址啊，仔细检查检查

import java.util.*;

public class A {
    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        System.out.print("Enter list1 size and contents:");
        int n = in.nextInt(); 
        int []List1 = new int[n];
        for(int i=0;i<List1.length;i++) {
            List1[i] = in.nextInt();
        }
        
        System.out.print("Enter list2 size and contents:");
         int m = in.nextInt();
         int []List2 = new int[m];
        for(int i=0;i<List2.length;i++) {
            List2[i] = in.nextInt();
        }
        
        System.out.print("List1 is ");
        for(int i=0;i<n;i++) {
            System.out.println(List1[i]+" ");
        }
        System.out.print("List2 is ");
        for(int p: List2) {
            System.out.println(p +" ");
        }
        
        int []List3 = new int[n+m];
        System.arraycopy(List1,0,List3,0,List1.length);
        System.arraycopy(List2, 0, List3, List1.length, List2.length);
        java.util.Arrays.sort(List3);
        
        
        System.out.print("The merged list is ");
        for(int p: List3) {
            System.out.print(p + " ");
        }
    }
