一问题：

二具体代码：

import java.util.Random;
import java.util.Scanner;

public class first {
    public static void main(String[] args) {

        int []usersnumbers=usernumslect();
        System.out.println("用户");
        for (int i = 0; i < 7; i++) {

        }
        System.out.println();
        judge(usersnumbers,lucknumber);
    }

    private static void judge(int[] usersnumbers, int[] lucknumber) {

            if(num1==6) System.out.println("恭喜您中将1万元");
            else System.out.println("遗憾，未中奖");
        }else{
            switch (num1){
                case 0:
                case 1:

                case 5: System.out.println("恭喜您，中将1000元");break;
                case 6: System.out.println("恭喜您，中将1万元");break;
            }
        }

    }

    private static int[] creatluvknumber() {
        Random sb=new Random();
        int[]nums=new int[7];
        int t;
        for (int i = 0; i < nums.length; i++) {
            nums[i]=-1;
        }
        out:
        for (int i = 0; i < nums.length-1; i++) {
            t= sb.nextInt(33)+1;
            for (int j = 0; j < nums.length-1; j++) {
                if(nums[j]==t){
                    i--;continue out;
                }
            }
            nums[i]=t;
        }
        nums[nums.length-1]=sb.nextInt(16)+1;
        return nums;
    }

    private static int[] usernumslect() {
        Scanner sc=new Scanner(System.in);
        int t;
        int[]nums=new int[7];
        for (int i = 0; i < nums.length; i++) {
            nums[i]=-1;
        }
        for (int i = 0; i < nums.length-1; i++) {
            System.out.println("请用户决定投注第"+(i+1)+"号号码(1~33)");
            t= sc.nextInt();
            for (int j = 0; j < nums.length-1; j++) {
                if(nums[j]==t){
                    System.out.println("投注重复号码，请重新输入~");
                    i--;break;
                }
                if(t<1||t>33){
                    System.out.println("投注超出范围，请重新输入~");
                    i--;break;
                }
            }
            nums[i]=t;
        }

        while (true) {
            System.out.println("请决定蓝色球号码");
            t= sc.nextInt();
            if(t<1||t>16){
                System.out.println("投注超出范围，请重新输入~");
            }else {
                nums[6]=t;break;
            }
        }
        return nums;
    }

}

三运行结果：
