Java - Converting a string into a rectangle

Question

I am reading a string from a file and I am getting a string variable from it. I would like to convert it into a rectangle variable. I am using the scanner class to read from the file. Here is my code.

    r = new Rectangle[ed];
        for(int i = 0;i < ed; i++){
            String rs = roomInfo.nextLine();
            r[i] = new Rectangle(rs);
    }

In my code I am reading from the file into a string and then you can see how I tried to convert it to a rectangle.

Answer 1

You should in some way parse the String into numbers, then you can create Rectangle objects from it.

Say, your string looks like this:

"0, 0, 20, 20"

That's

"<x>, <y>, <width>, <hight>"

Then here's what you have to do:

String[] split = str.split("[,]");
Rectangle rect = new Rectangle(split[0], split[1], split[2], split[3]);

Other string formats require other techniques.
