You have disabled cookies and are browsing in private mode. Every time you call the myMethod method, the code executes from the top with no memory about what it did on previous executions unless, of course, you changed some fields of the MyClass object.
Apologies for the late reply, I've been in work. The new operator instantiates a class by allocating memory for a new object and returning a reference to that memory. In this case, multirelease.

Each constructor lets you provide initial values for the rectangle's origin, width, and height, using both primitive and reference types.
Similar complaints have been levied against dynamically-typed languages for years. Based on its names, once seems to write, the other one seems to read. This makes pauses for garbage collection far less stressful on application performance. Coming back to your original question, yes, this instantiates a new object each time the method is called. If you don't understand what I mean just ask.
