Why "private CurrentWeather currentWeather;" and not "... currentWeather = new CurrentWeather();"?

I suppose this is just more of a general Java/Android question rather than specific to this lesson.

The keyword "private" lets the program know that only this class can use that variable.

private CurrentWeather currentWeather; is declaring the variable so it can be initialized later in the program this works well for if it needs to be created using input from the user.

CurrentWeather currentWeather = new CurrentWeather(); does both declaration and initialization all at once. This can save time but like i said the other way is sometimes better for giving the variable a value based on input.

Mostly this is just a style choice and not something you really need to worry about.

Goodluck! --Ricky
