我有一个问题，如何删除重复值的数组，有人能帮我吗？我有这个代码只是为了合并2个数组和显示结果，但我不知道如何删除重复的输入(对不起，我刚开始学java。）

public static void main(String... args) {
    int[] x = new int[3];
    int[] y = new int[3];
    int[] xy = new int[6];/***new array to hold the integers of arrays x and y****/
    int temp, c = 0;
    Scanner myInput = new Scanner(System.in);
    /***input of array x at the same time storing the integers to array xy***/
    System.out.println("enter 3 integers for array x:");
    for (int a = 0; a < 3; a++) {
        x[a] = myInput.nextInt();
        xy[c] = x[a];
        c++;
    }
    /***input of array y at the same time storing the integers to array xy***/
    System.out.println("enter 3 integers for array y:");
    for (int b = 0; b < 3; b++) {
        y[b] = myInput.nextInt();
        xy[c] = y[b];
        c++;
    }
    /*sorting...*/
    for (int i = 0; i < 6; i++) {
        for (int j = 0; j < 5 - i; j++) {
            if (xy[j] > xy[j + 1]) {
                temp = xy[j];
                xy[j] = xy[j + 1];
                xy[j + 1] = temp;
            }
        }
    }
    /*printing of array xy sorted*/
    for (int w = 0; w < 6; w++)
        System.out.print(xy[w] + "   ");
}
