Why its giving this msg " Exception in thread "main" java.lang.NoSuchMethodError: mai

// Java packages
import java.awt.Graphics; // import class Graphics
import javax.swing.JApplet; // import class JApplet

public class WelcomeApplet2 extends JApplet {

// draw text on applet’s background
public void paint( Graphics g )
{
// call superclass version of method paint
super.paint( g );

// draw two Strings at different locations
g.drawString( "Welcome to", 25, 25 );
g.drawString( "Java Programming!", 25, 40 );

} // end method paint

} // end class WelcomeApplet2





/* when i compfile javac WelcomeApplet2.java its fine it make the class file then run the class file

You're trying to run it like an application, which has to have a main() method. Applets you run with the applet runner or put them in a web page and run them in a browser.

Hi

I'm getting this error as well when I compile this program with when I try to run this program.

F:\jdk6\bin>javac Motocycle.java

F:\jdk6\bin>java Motocycle
Exception in thread "main" java.lang.NoSuchMethodError: main



class Motorcycle
{
String make;
String color;
boolean enginstate;


public static void main (String args[])
{
Motorcycle m = new Motorcycle();
m.make = "Yamaha RZ350";
m.color = "Yellow";
System.out.println("calling showAtts...");
m.showAtts();

System.out.println("--------");
System.out.println("Starting engine....");
m.startEngine();

System.out.println("--------");
System.out.println("Starting showAtts....");
m.showAtts();

System.out.println("--------");
System.out.println("Starting engine....");
m.startEngine();
}

void startEngine()
{
if (enginstate == true)
System.out.println("The engine is aready on.");
else
{
enginstate = true;
System.out.println("The engine is now on.");
}
}

void showAtts()
{
System.out.println("This motocycle is a " + color + " " + make);

if ( enginstate = true)
System.out.println("The engine is off ");
else
System.out.println("The engine is on " );
}



}

:SICK:

Saw it right after my submission:

F:\jdk6\bin>javac Motocycle.java

F:\jdk6\bin>java Motocycle
Exception in thread "main" java.lang.NoSuchMethodError: main


Forgot the r in Motocycle / F:\jdk6\bin>javac Motorcycle.java

F:\jdk6\bin>java Motorcycle

The program ran fine

Bye :)
