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

Task: Write codes to achieve the following outcome.

Hint: Use a variable full_name to combine the first name and family name.
