How To Use Command Line Arguments in Eclipse ?
Labels:
Java
A Java application allows users to enter command line arguments at runtime, and also users can enter N number of arguments using command line.
Here in this post we have created a simple Arithmetic Application to add 2 numbers that get passed as Command Line Arguments.
1. Create a Java Application AdditionJar.
2. Create a class named Addition inside com.arithmetic package.
3. Get the two command line arguments and convert it into Integer like below.
4. Go to project properties –> Run/Debug Settings –> Click Addition –> Edit
5. Once done with click of edit button , goto arguments –> Enter the first and second argument with a space.
6. Output window displays the addition of two command line arguments.

package com.arithmetic;
public class Addition {
/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
int number1=Integer.parseInt(args[0]);
int number2=Integer.parseInt(args[1]);
System.out.println("Addition of given two numbers:"+(number1+number2));
}
}
