合并两个有序数组，并进行排序和去重（Java实现）

import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;
import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        String  s1 = sc.nextLine();
        String  s2 = sc.nextLine();
        String[] arrs1 = s1.split(" ");
        String[] arrs2 = s2.split(" ");
        int[] arr1 = new int[arrs1.length];
        int[] arr2 = new int[arrs2.length];
        for (int i = 0; i < arrs1.length; i++) {
            arr1[i] = Integer.valueOf(arrs1[i]);
        }
        for (int i = 0; i < arrs2.length; i++) {
            arr2[i] = Integer.valueOf(arrs2[i]);
        }

        test(arr1,arr2);
    }

    public static void test(int[] arr1, int[] arr2 ){
        int n = arr1.length+arr2.length;
        int[] arr = new int[n];
        for (int i = 0; i < n; i++) {
            if (i < arr1.length) {
                arr[i] = arr1[i];
            }
            else {
                arr[i] = arr2[i-arr1.length];
            }
        }
        Arrays.sort(arr);

        List<Integer> list = new ArrayList<>();
        for (int i = 0; i < n; i++) {
            if (!list.contains(arr[i])) {
                list.add(arr[i]);
                System.out.print(arr[i]+ " ");
            }
        }
    }
}

输入：

1 2 3 4 5
2 4 6

输出：

1 2 3 4 5 6
