In the example described here we will explains you how to print the message on console, program also teaches you how to write a method for calculating the sum of the two numbers.

The video tutorial of this example explains you all the steps necessary to make the project and run the example. In a nutshell the steps to create project with Eclipse are:

The Eclipse IDE will create a project for you. You can see the complete detail in the video of this tutorial.

Step 3: Add the following source code into the file (FirstExample.java):

package com.devmanuals;

public class FirstExample {

	public static void main(String[] args) {

		int s = sum(2,8);
		
		System.out.println("Calculated is Sum:" +s);

	}
	
	public static void sayHello(){
		
		System.out.println("Hi, welcome to Java Programming...");
	}
	
	/*
	public static void sum(int i, int j){
		int k = i+j;
		System.out.println("Sum:" +k);
	}*/
	
	public static int sum(int i, int j){
		int k = i+j;
		return k;
	}	

}

Here is the screen shot from the Eclipse project:

Step 4: Run the example code

Now right click on the source code window and then select "Run as Java application" to
