Passing Command Line Argument in Eclipse

---

Passing command line arguments in Eclipse is very easy.We will see step by step procedure to pass command line arguments to a java program using eclipse.

package com.techy.rajeev;

class BadFoodException extends Exception {

}
class Myexception{
    public static void checkfood(String food)throws BadFoodException{
        if(food.equals("Veg")){
            System.out.println("Good food :)");
        }else{
            throw new BadFoodException();
        }
    }
    public static void main(String args[]){
        for(String s: args){
            try {
                checkfood(s);
            } catch (BadFoodException e) {
                e.printStackTrace();
            }
        }
        System.out.println("survived");
    }
}

This is the java program for which we want to pass command line arguments.

Write this program in eclipse IDE and save it.

A drop down menu will appear.Now click on Run Configurations.
