MENDAPATKAN

INPUT DARI
KEYBOARD

Tujuan




Membuat program kita lebih
interaktif dengan menggunakan
input dari keyboard
Menggunakan kelas BufferedReader
dan melalui GUI (Graphical User
Interface) dengan menggunakan
kelas JOptionPane.

Menggunakan BufferedReader


Tambahkan di bagian paling atas code
anda:
import java.io.BufferedReader; import
java.io.InputStreamReader; import
java.io.IOException;



Tambahkan dibawah viod main :
BufferedReader dataIn = new
BufferedReader(new
InputStreamReader( System.in) );

Contoh
package inputkey;
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.io.IOException;
public class Main{
public static void main( String[] args ){

BufferedReader dataIn = new BufferedReader(new
InputStreamReader( System.in) );
String name = "";
System.out.print("Please Enter Your Name:");
try
{ name = dataIn.readLine();}
catch( IOException e ){ System.out.println( " Error
");}
System.out.println("Hello " + name + " ! ");
}}

package inputkey;
import java.io.*;
public class Main
{
public static void main( String[] args )
{
BufferedReader dataIn = new BufferedReader(new
InputStreamReader( System.in) );
String name = "";

System.out.print("Please Enter Your Name:");
try
{
name = dataIn.readLine();
}
catch( IOException e )
{
System.out.println( " Error ");
}
System.out.println("Hello " + name + " ! ");
}
}

Menggunakan Scanner


Tambahkan di bagian paling atas
code anda:

import java.util.*;



Tambahkan dibawah viod main :

Scanner baca = new
Scanner(System.in);

package satu;
import java.util.*;
public class Main
{
public static void main(String[] args)
{
Scanner baca = new Scanner(System.in);
int nilai;
System.out.print(“Input Anda = ");
nilai = baca.nextInt();
System.out.println("Nilai Anda = " +nilai);
}
}

Menggunakan JOptionPane




Tambahkan di bagian paling atas code
anda:
import javax.swing.JOptionPane;
Tambahkan dibawah viod main :
name = JOptionPane.showInputDialog("Please
enter your name");
String msg = "Hello " + name + "!";
JOptionPane.showMessageDialog(null, msg);

package jopt;
import javax.swing.JOptionPane;
public class Main {
public static void main(String[] args)
{

String name = "";
name = JOptionPane.showInputDialog("Please
enter your name");
String msg = "Hello " + name + "!";
JOptionPane.showMessageDialog(null, msg);
}
}
