Instance vs. Class Variables

Constants Revisited:

class ConstantExample {

final int iMAXSIZE = 10;

} // of ConstantExample

class ConstantExample {

static final int iMAXSIZE = 10;

} // of ConstantExample

Declares a different-but-identical constantfor each instance of the class.

Wasteful with zero benefit.

Declares a single constant for use by all instances of the class.
