You could make the variables public fields:
public int width;
public int height;
DrawFrame() {
this.width = 400;
this.height = 400;
}
You could then access the variables like so:
DrawFrame frame = new DrawFrame();
int theWidth = frame.width;
int theHeight = frame.height;
A better solution, however, would be to make the variables private fields add two accessor methods to your class, keeping the data in the DrawFrame class encapsulated:
private int width;
private int height;
DrawFrame() {
this.width = 400;
this.height = 400;
}
public int getWidth() {
return this.width;
}
public int getHeight() {
return this.height;
}
Then you can get the width/height like so:
DrawFrame frame = new DrawFrame();
int theWidth = frame.getWidth();
int theHeight = frame.getHeight();
I strongly suggest you use the latter method.
