Rectangle Intersection

[Gwindow]

I am trying to make the program output that the Rectangles intersect. This is my code, when I run it, I get a list of exceptions. Can someone help me out?

public Rectangle playerRec(){ ///playerRec() makes new rect
Rectangle playerRec=new Rectangle(playerX,playerY,playerW,playerH); //x,y,w,h
System.out.println("Player "+playerRec.getBounds());
return null;
}
public Rectangle enemyRec(){ ///enemyRec() makes new rect
Rectangle enemyRec=new Rectangle(enemyX, enemyY, enemyW, enemyH); //x,y,w,h
System.out.println("Enemy "+enemyRec.getBounds());
return null;
}

public void collision() {
enemyRec();
playerRec();
if(playerRec().intersects(enemyRec())) {
System.out.println("INTERSECTS");
}
}

These will tell what the trouble is. If you post them we might be able to help.
