Thread: generics with underclass

hallo everyone,

i am learning java, i am trying to learn now the Generics. i have written this program and i dont know why i keep getting error "Command execution failed.".

public class Mavenproject2 {

public static void Main(String[] args){
underclass <Double> taha = new underclass <>(4.0, 5.0);

taha.display();

}
}

public class underclass <T> extends Superclass{

T breite;
T hoehe;

public underclass(T breite, T hoehe){
super(4);
this.breite=breite;
this.hoehe=hoehe;
}

public void display(){
System.out.println("breite = " + this.breite + "hoehe" + this.hoehe + "ecken" + super.getEcken());
}

}
public abstract class Superclass {
Integer Ecken;

public Superclass(Integer Ecken){
this.Ecken=Ecken;
}
public Integer getEcken(){
return Ecken;
}

The problem is with your Main function. You should have:

public static void main(String[] args)

not

public static void Main(String[] args)
