I presume that's where 'static' comes from - it doesn't reset the value (as opposed to a const where the value cannot change) | In Head First Java, there is a nice explanation of static. Static means stable not changing thats obvious from meaning and its quite obvious that it does not change.

I presume that's where 'static' comes from - it doesn't reset the value (as opposed to a const where the value cannot change) | I suppose the best way to think of it is that "static" means unchanging, and it is the *location* of the variable that is unchanging when when you switch between the different instances of a class. The main thing is to eradicate any thought from your mind that the *value* of a static variable is unchanging: it may even... |
