I have a question about this...
I'm learning Java by myself using a book by Deitel and Deitel.
I was doing this one:
//programa de suma
import java.awt.*; //importar paquete java.awt
import java.applet.Applet;
public class Addition extends java.applet.Applet {
Label prompt; //solicta entrada al usuario
TextField input; //introducir valores
int number; //almacenar valor introducido
int sum; //almacenar suma de enteros
//preparar componentes de interfaz grafica de usuario e incializar variables
/** Initialization method that will be called after the applet is loaded
* into the browser.
*/
public void init() {
prompt = new Label( "Teclee un numero y presionae Intro: ");
input = new TextField(10);
add(prompt); //poner prompt (solicitud) en la applet
add(input); //poner input(entrada) en la applet
sum=0; //hacer suma igual a cero
// TODO start asynchronous download of heavy resources
}
//procesar la accion del usuario en el campo de texto de entrada public boolean action(Event e,Object o)
public boolean action( Event e, Object o)
{
Integer.parseInt( o.toString() ); //obtener numero
input.setText( "" ); //despejar campo de entrada de datos
sum= sum + number; //suma numero a suma
showStatus( Integer.toString(sum)); //mostrar resultado
return true; //indica que la accion del usuario se proceso
}
// TODO overwrite start(), stop() and destroy() methods
}

Well, when i tried to compile i got this error:
init:
deps-jar:
Compiling 1 source file to C:\Documents and Settings\alhela\Welcome\build\classes
Note: C:\Documents and Settings\alhela\Welcome\src\Addition.java uses or overrides a deprecated API.
Note: Recompile with -Xlint:deprecation for details.
compile:
run:
BUILD SUCCESSFUL (total time: 4 seconds)
-
I already searched the forum and found something similar, but it didin't help very much.
What should i do? and How?
What is "-Xlint"?
