Question

I was doing some swing java and ran into this (im still new to programming).

int maxXvalue = getSize().width;

basically is this a variable defined within a method called getSize() ?

I know for class variables its: className.variableName

I know for objects variables its: object.variableName

so for methods is it?: method().variableName

also in java how do i access inner class variables?
For example, a class named “Class” containing a subclass called “InnerClass”:

would it be: Class.InnerClass.variable

or would it be just be: InnerClass.variable
without the container class referenced

Thanks for clearing up the confusion and misconceptions

Answer 1

getSize() is just returning an instance of a Dimension Object

width is just a field within that object.
