题目，上图！！

上代码

import java.util.Scanner;
public class homework01 {
    public static void main(String[] args) {
        Scanner input = new Scanner(System.in);
        System.out.print("Enter the number of values: ");
        int num = input.nextInt();
        int[] values = new int[num];
        System.out.print("Enter the values: ");
        for (int i = 0; i < num; i++)
            values[i] = input.nextInt();
        if(isConsecutiveFour(values))
            System.out.println("True");
        else
            System.out.println("Flase");
        input.close();
    }
    public static boolean isConsecutiveFour(int[] values){
        for (int i = 0; i < values.length - 4; i++){
            boolean flag = true;
            for(int j = 1; j < 4; j++)
                if(values[i+j] != values[i]) {
                    flag = false;
                    break;
                }
            if(flag)
                return true;
        }
        return false;
    }
}
