如果语句内的try catch语句没有检测到try/catch部分

Question

所以我有一个类的任务，我完全卡住了。我整个学期都在这里潜伏，并且找到了我需要的东西，但是这次我迷路了。我需要帮助一个循环内的try catch语句。该任务要求我们让人们输入他们的姓名，并选择一个时间表1,2,3,4,5,6，如果超出该范围或时间已被占用，则有例外。继承人到目前为止我所拥有的。当运行时，它会让我把第一个名字放入并且一次，但是给第40行，这是"if(timeSlot[i] <1 || >6){ "行的错误。

任何帮助，将不胜感激，谢谢

import java.util.Scanner; 

public class Scheduler { 

Scanner input = new Scanner(System.in); 

public static void main(String[] args) throws TimeInUseException, 
     InvalidTimeException { 
    // TODO Auto-generated method stub 
    Scanner input = new Scanner(System.in); 
    String name[] = new String[6]; 
    int timeSlot[] = new int[6]; 

    //as long as there is less than 6 it will keep running 
    int d = 0; 
    while (d < 6) { 

     //try block to see if the time slot has been taken 
     try { 
      for (int i = 0; i < name.length; i++) { 

       //ask for the name 
       System.out.println("Please type your name: "); 
       name[i] = input.nextLine(); 

       //ask for the time 
       System.out.println("Please select a time: 1, 2, " 
         + "3, 4, 5, 6"); 
       timeSlot[i] = input.nextInt(); 

          // if the time is less than 1 or greater than 6 
       // it will throw an invalid time exception 
       if (timeSlot[i] < 1 || timeSlot[i] > 6) { 
        throw (new InvalidTimeException()); 
       } 

          // if the time slot is not equal to null(not empty) 
       // it will throw a time in use exception 
       if (timeSlot[i] != null) { 
        throw (new TimeInUseException()); 
       } 

      } 
     } // catch for invalid time 
     catch (InvalidTimeException ite) { 
      ite.getMessage(); 
     } //catch for time in use 
     catch (TimeInUseException tiue) { 
      tiue.getMessage(); 
     } 
     d++; 

    } 
    for (int i = 0; i < 6; i++) { 
     System.out.println(name[i] + " has an appointment at: " 
       + timeSlot[i]); 

    } 

} 
} 

例外每个请求

public class InvalidTimeException extends Exception{ 

//sets the String to say time is in use 
public InvalidTimeException(String message) { 
    super(message); 
    message = "That time is invalid, please enter either 1, 2, 3, 4, 5, or 6"; 

    } 

InvalidTimeException() { 
    throw new UnsupportedOperationException("That time is invalid, please enter either 1, 2, 3, 4, 5, or 6"); //To change body of generated methods, choose Tools | Templates. 
} 


} 

，第二个

public class TimeInUseException extends Exception { 

//sets the String to say time is in use 
    public TimeInUseException(String message) { 
     super(message); 
    // message = "That time is already in use, please select another"; 
    } 


TimeInUseException() { 
    throw new UnsupportedOperationException("That time is already in use, " 
      + "please select another"); 
} 


} 

Answer 1

更改您的语句来if(timeSlot[i] < 1 || timeSlot[i] > 6)。

Answer 2

您的catch块位于错误的位置。他们应该立即后你的尝试块而不是里面。我并不完全明白你在循环中对你的想要做什么，因此可能还有其他一些问题，但这应该是一个开始。

Answer 3

你在第40行得到的是一个合成错误。您必须在逻辑OR语句中明确指定要输入的条件 - Java编译器在这里不会猜测您想要检查timeSlot数组中的值是否大于6.您拥有什么要做的是类型：

if(timeSlot[i] < 1 || timeSlot[i] > 6){ 
    throw new InvalidTimeException(); 
}   

除此之外，你的catch块超出范围，不能在for循环。
