Using int and String

Now you have a rough idea about the Data Types. So now it's time for a simple calculation.

We know numeric values can be used in 'int' data type ant texts in 'String'.
Okay let's go...

1. Open Eclipse
2. File >  New > Java Project 
3. Type a project name
4. Right click 'src'
5. New > Class
6. Give it a name

Now it's for the coding

   public class main {

   public static void main(String []args){

int total;

int x = 20 ;

int y = 10 ;

total = x+y ;

System.out.println(total);

       }

 }

Let's Print a name

  

public class main {

public static void main(String []args){

String fname = "David" ;

String sname = "Miller";

String fullname = fname + sname ;

System.out.println(fullname);

}

}
