I am trying to declare an Array of Rectangles in java but I can't figure out how. Here is my code:
private Rectangle rectArray[] = new Rectangle[9];
rectArray[0] = new Rectangle(0,0,0,0);
I tried commenting out the second line and it works fine, but when I leave the second line in, it has the error:
Syntax error on token ";" expected {
It's not declaring the Array that's the problem; initializing it is the problem. How can I fix this error?
private Rectangle rectArray[] = new Rectangle[9];
rectArray[0] = new Rectangle(0,0,0,0);
You have to initialize within constructor (generally constructor (or even initilisation block) than method for init).
In your case, you mixed field (as suggested by your private keyword) with computation, leading to the compilation error you got.
You may want to do:
MyClass {
private Rectangle rectArray[] = new Rectangle[9];
MyClass() {
rectArray[0] = new Rectangle(0,0,0,0);
}
}
private is used for annotating an object's field, not a local variable. You cannot write some "process" directly on the class. You have to wrap it in a constructor, initialisation block or method. Indeed, this line: rectArray[0] = new Rectangle(0,0,0,0); is what I called a "process", since you use data (the array) your initialized. All the init process concerning a field should be inlined, that is not your case.
Rectangle[] var = instead of Rectangle var[]. It makes it clear that it's an array of Rectangle objects.
{ }characters, but it's probably not what you want to do.
