Hola mundo
En python:
print "Hello World!"
En java:
public class Hello { public static void main(String[] args) { System.out.println("Hello World!"); } }
Ejemplo de lectura con Scanner
import java.util.Scanner; public class TempConv { public static void main(String[] args) { Double fahr; Double cel; Scanner in; in = new Scanner(System.in); System.out.println("Enter the temperature in F: "); fahr = in.nextDouble(); cel = (fahr - 32) * 5.0/9.0; System.out.println("The temperature in C is: " + cel); System.exit(0); } }
Ejemplo con swing
import javax.swing.*; public class TempConvGUI { public static void main(String[] args) { String fahrString; Double fahr, cel; fahrString = JOptionPane.showInputDialog("Enter the temperature in F"); fahr = new Double(fahrString); cel = (fahr - 32) * 5.0/9.0; JOptionPane.showMessageDialog(null,"The temperature in C is, " + cel); } }
