This week's book giveaway is in the Mac OS forum. We're giving away four copies of a choice of "Take Control of Upgrading to Yosemite" or "Take Control of Automating Your Mac" and have Joe Kissell on-line! See this thread for details.
Java follows the declaration before read rule. In the first case, you are trying to assing a value to a variable. In this case, the variable is to the left side of = whereas in the second case you are trying to read the variable before declaration ie., variable on the right hand side of =. This is not acceptable in java.
