Java Examples - Exception with overloaded Methods

Problem Description

How to handle the exception with overloaded methods ?

Solution

This example shows how to handle the exception with overloaded methods. You need to have a try catch block in each method or where the are used.

public class Main {
   double method(int i) throws Exception {
      return i/0;
   }
   boolean method(boolean b) {
      return !b;
   }
   static double method(int x, double y) throws Exception {
      return x + y ;
   }
   static double method(double x, double y) {
      return x + y - 3;
   }   
   public static void main(String[] args) {
      Main mn = new Main();
      try {
         System.out.println(method(10, 20.0));
         System.out.println(method(10.0, 20));
         System.out.println(method(10.0, 20.0));
         System.out.println(mn.method(10));
      } catch (Exception ex) {
         System.out.println("exception occoure: "+ ex);
      }
   }
}

Result

The above code sample will produce the following result.

30.0
27.0
27.0
exception occoure: java.lang.ArithmeticException: / by zero

The following is an another example to handle the exception with overloaded methods in Java

class NewClass1 { 
   void msg()throws Exception{System.out.println("this is parent");}
}
public class NewClass extends NewClass1 {
   NewClass() {
   }
   void msg()throws ArithmeticException{System.out.println("This is child");}
   public static void main(String args[]) {
      NewClass1 n = new NewClass();
      try {
         n.msg();
      } catch(Exception e){}
   }  
}

The above code sample will produce the following result.

This is child
