nullpointerexception当从矩形数组中检索矩形

所以我有一个类处理按钮，我有一个包含2个独立矩形形状的矩形数组。现在，当我做一个变量，检索数组中的第0个索引时，它会给我一个nullpointerexception我一直在挠我的头，我已经清楚地声明并初始化数组，并使其包含2个矩形的适当大小，已将这些分配给索引。我必须错过一些我似乎无法想象的小事。nullpointerexception当从矩形数组中检索矩形

下面我已经把相关的代码如下：

public class MenuButton { 

private int height; 
private int width; 
private float positionX; 
private float positionY; 

//private ArrayList<Rectangle> rects; 
private Rectangle rects[]; 

private Rectangle play; 
private Rectangle touchToPlay; 

private boolean isTouched; 

public MenuButton(int height, int width, float positionX, float positionY){ 

    this.height = height; 
    this.width = width; 
    this.positionX = positionX; 
    this.positionY = positionY; 

    isTouched = false; 
    Rectangle rects[] = new Rectangle[2]; 
    play = new Rectangle(positionX, positionY, width, height); 
    touchToPlay = new Rectangle(positionX, positionY, width, height); 


    //can clean this up by introducing initButtons() to assign buttons to 
    //indexes of the array 
    rects[0] = play; 
    rects[1] = touchToPlay; 

} 


public boolean isClicked(int index,float screenX, float screenY){ 

    //ERROR IS BELOW THIS LINE 
    Rectangle rect = rects[0]; 

    return rect.contains(screenX, screenY); 
}
