nullpointerexception當從矩形數組中檢索矩形

所以我有一個類處理按鈕，我有一個包含2個獨立矩形形狀的矩形數組。現在，當我做一個變量，檢索數組中的第0個索引時，它會給我一個nullpointerexception我一直在撓我的頭，我已經清楚地聲明並初始化數組，並使其包含2個矩形的適當大小，已將這些分配給索引。我必須錯過一些我似乎無法想象的小事。nullpointerexception當從矩形數組中檢索矩形

下面我已經把相關的代碼如下：

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); 
}
