Query on what I did wrong

[Muppetlol]

// This is for Circle.Java

package Circle;
public class Circle {
private double radius;
public Circle() 
{
radius = 2.0;
}
public double getRadius()
{
return radius;
}
public double getArea() 
{
return radius*radius*Math.PI;
}
public void printMe() 
{
System.out.println("ID is 2015");
}
}

//This is for Cylinder.Java

package Circle;
public class Cylinder extends Circle {
    private double height;
public Cylinder() 
{
super();
height = 2.5;
}
public double getHeight() 
{
return height;
}
public double getVolume() 
{
return height*getArea();
}
@Override
public void printMe() 
{
System.out.println("Color is blue");
}
void print()
{
.printMe();
.printMe();
}
public static void main(String[] args){
Cylinder cy1 = new Cylinder();
System.out.println("Radius is " + cy1.getRadius()+" Height is " + cy1.getHeight()+ " Base area is " + cy1.getArea()+ " Volume is " + cy1.getVolume());
cy1.print();
}
    
}

My

package Circle;

is being underlined in both file.

In my Cylinder.java , I do not understand the part where it says

void print()
{
.printMe(); //I am suppose to type something in front but i don't know what I'm suppose to
.printMe(); //I am suppose to type something in front but i don't know what I'm suppose to
}

Help would be appreciated, did I miss out something in some part of my code>

this is not a java forum. what makes you think you can post java code here and get help with it?

Use the super keyword to access a method/field of a class' superclass. I don't remember much about packages but your folder structure should resemble the package structure (so your stuff should be in some folder named Circle...I think).

I guess users not posting compiler errors doesn't really vary with language.

Smells like homework. Anyways as 4 days has passed now, here are some hints/tips:
1) You are using identifier "Circle" as both class name & package name
2) Try "this" & "super" before "." and try to figure out what the program is doing when each keyword is used
3) Indent your code
