NETBEANS Java Basics 106 – Getting Inputs

PREREQUISITE

Download NetBeans from https://netbeans.org/downloads/ 

STEPS

1) Open the Startup Project.

Refer previous tutorial, http://javadevsteps.blogspot.com/2014/08/netbeans-java-basics-101-getting-started.html .

package firstproject; public class FirstProject {     public static void main(String[] args) {         // TODO code application logic here     }   }

2) EDIT THE CODES.

2-1) Add:

a) A Scanner library import declaration statement (in the import declaration section).

package firstproject; import java.util.Scanner; public class FirstProject {     public static void main(String[] args) {         // TODO code application logic here     }   }

b) A Scanner object declaration statement (in the main method)

package firstproject; import java.util.Scanner; public class FirstProject {     public static void main(String[] args) {                 Scanner user_input = new Scanner( System.in );     }   }

c) A String variable declaration statement (in the main method)

package firstproject; import java.util.Scanner; public class FirstProject {     public static void main(String[] args) {                 Scanner user_input = new Scanner( System.in );                 String first_name;     }   }

d) An input request output statement (in the main method)

package firstproject; import java.util.Scanner; public class FirstProject {     public static void main(String[] args) {                 Scanner user_input = new Scanner( System.in );                 String first_name;                 System.out.print("Enter your first name: ");     }   }

e) A String input statement (in the main method)

package firstproject; import java.util.Scanner; public class FirstProject {     public static void main(String[] args) {                 Scanner user_input = new Scanner( System.in );                 String first_name;                 System.out.print("Enter your first name: ");                 first_name = user_input.next( );     }   }

f) A String output statement (in the main method)

package firstproject; import java.util.Scanner; public class FirstProject {     public static void main(String[] args) {                 Scanner user_input = new Scanner( System.in );                 String first_name;                 System.out.print("Enter your first name: ");                 first_name = user_input.next( );                 System.out.println("You are " + first_name);     }   }

2-2) Run.

3) FURTHER EDITS
