java - 在某些输入后停止用户输入？

Question

我正在解决一个非常简单的Java问题，我需要在输入某个用户值后停止接收数据。输入值后，用户仍然可以输入数据，但输入值后，输出不应包含该值或该值后面的任何数据。另外，我试图将负数条目排除在计数之外，但无济于事。这是我的代码。任何帮助，将不胜感激!谢谢!

import java.util.Scanner;

public class Sample
{
    public static void main (String[] args) 
    {
        System.out.println("Please input any number, up to 10 entries. "
                + "Enter -1 to exit: ");
        Scanner read = new Scanner(System.in);
        int[] input_array = new int[10];
        int numOfEntries = 0;
        for(int i = 0; i < input_array.length; i++)
        {
            input_array[i] = read.nextInt();
            numOfEntries++;
            //only positive numbers
            if(input_array[i] >= 100 || input_array[i] < 0)
            { 
                if(input_array[i] == 77) //certain value
                { 
                    //entries before 77 is entered become the new array
                    numOfEntries = i;
                    int[] new_array = new int[numOfEntries];
                    for (int j = 0; j < numOfEntries; j++)
                    {
                        new_array[j] = input_array[i];
                    }
                    System.out.print(new_array[numOfEntries] + " ");
                }               
                if(input_array[i] == -1) //exit loop
                {
                    break;
                }
                System.out.println("Please enter a positive 
                number that is less than 100.");
            }
        }   

        //final result
        System.out.println("Your entries are: ");
        for (int i = 0; i < numOfEntries; i++)
        {
            System.out.print(input_array[i] + " ");
        }

您应该像这样检查以确保一切都正确地通过条件

//all this goes inside the for loop
    String input = read.nextInt();
    if (input == -1)
        break;
    if (input > 0)//is it negative? 
    {
        if (input < 100)//is it greater than 100?
        {
           if (input == 77)//is it 77?
           {
               //your code
           } 
           else//this will run when all conditions are passed
             input_array[i] = input; 
        }
    }
