try catch!?

[Joe2003]

Hey

I have a load of check functions, TONS of them. Anyway each one returns a boolean value, all need to return true. Is there a way of implementing some form of try catch that will "catch" an error of false being returned? I dont want to have to include loads of ifs, is there a way round this, ie generating my own exception, which is "returned = false"? Thanks

Code:

try
{
          checkName();
          checkAge();
          checkFace();
          checkFoot();
          checkGas();
          checkMate();
}
catch()
{
          System.out.println("A false was returned");
}

Why not have the check functions return void and then throw an exception if a validation failure occurs, the function could wrap up the details inside the exception

To add to jelly's reply, here's an example:

Code:

import java.util.*;
public class Main{
	public static void main(String[] arg){
		int number = 10;
		try{
			number = addInteger(number, -5);
			System.out.println("number = " + number);
		} catch (Exception e) {
			System.out.println("Error: " + e.getMessage());
		}
		pause();
	}
	public static int addInteger(int number, int positiveNumber) throws Exception {
		if (positiveNumber < 0){
			// Oops!
			throw new Exception("positiveNumber cannot be negative");
		} else {
			return number + positiveNumber;
		}
	}
	protected static void pause(){
		Scanner scanner = new Scanner(System.in);
		scanner.nextLine();
	}
}

will output

Code:

Error: positiveNumber cannot be negative

Hope that helped you.
