没有合适的构造函数发现异常（int）

Question

我不知道我的代码在哪里投掷它的流。它有我不知道他们如何工作的各种错误。通过类异常的控制流不支持super（int）的超级参数，就像super（string）类型一样。我大多是Java新手，这是一个基于用户的异常处理程序。

import java.util.*; 
class invalidbal extends Exception{ 
    invalidbal (int balance, int transaction){ 
    super(balance); 
    super(transaction); 
} 
class TestCustomException1{ 

static void validate(int balance, int transaction)throws invalidbal{ 
     if(balance - transaction < 0) 
      throw new InvalidAgeException("You are not eligible to Transact"); 
     else 
      System.out.println("Post transaction your current balance is" + (balance - transaction)); 
} 

public static void main(String args[]){ 
Scanner s = new Scanner(System.in); 
     System.out.println("Welcome to transaction checker"); 
    System.out.println("Please enter the balance:"); 
    a = s.nextInt(); 
    System.out.println("Please enter the transaction:"); 
    b = s.nextInt(); 
     try{ 
      validate(a,b); 
     }catch(Exception m){System.out.println("Exception occured: "+m);} 

    System.out.println("Thank you for checking!"); 
     } 
    } 
} 

输出如下。

进入每在Java文档here没有用于Exception类没有构造函数输入作为int代码hereAs，所以你得到这些错误：从invalidbal()构造

删除follwoing行代码

super(balance); 
super(transaction);
