Class Instance initialization fails

[JOHNINALBANY]

The following statements trigger an error (Exception in thread "main" java.lang.NullPointerException) in the below class. Why?

Rect[0]=new Rectangle2D.Double(50,50,70,70);
Rect[1]=new Rectangle2D.Double(80,80,100,100);

Due to the above error I am forced to create the instances like this (see below code):

Rectangle2D[] Rect1 = {new Rectangle2D.Double(50,50,70,70),new Rectangle2D.Double(80,80,100,100)};

In the event of having many rectangles the above statement would be long and difficult to read. Is there a fix for this? I would like to initialize every single Rectangle like this Rect[i]= new Rectangle2D.Double(6,7,10,10);



Thanks

class Frame extends JFrame {

Rectangle2D[] Rect;


Frame(){

//The following statements trigger an error:
//Error: Exception in thread "main" java.lang.NullPointerException
Rect[0]=new Rectangle2D.Double(50,50,70,70);
Rect[1]=new Rectangle2D.Double(80,80,100,100);

// The following statement works
//In the event of having many rectangles this would be difficult to read
Rectangle2D[] Rect1 = {new Rectangle2D.Double(50,50,70,70),new Rectangle2D.Double(80,80,100,100)};

setTitle("Test");
setSize(300,300);
add(new DrawFigures(Rect));
}

}

This just declares the array:

MyType[] myArray;

You need to initialize it as well:

MyType[] myArray = new MyType[25];  // if we want an array of 25 MyType objects

Sorry for the delay. Thanks for your valuable help.

Not a Java 2D problem. Moving to New to Java.
