ystem.out.println(floozy); // Problem 1: 97.4

System.out.println(xray[2]); //Problem 3: 100
System.out.println(s); //Problem 4: Hello
This is because out of all of the variables that the myMethod gives a value to, the only variable that is being saved back to the global variable in the main method is a[2]. The other variables are being saved as instance variables and not being returned. Therefore, when the println statements are called they target the local variables in the main method.

A warm site is a type of facility an organization uses to recover its technology infrastructure when its primary data center goes down.
Warm sites might have backups on hand, but they may not be complete this means that a warm site is configured with power, phone, network etc. may have servers and other resources. But a warm site is not ready for immediate switch over because it still needs to be installed and configured.
Therefore, a warm site is A SEPARATE FACILITY WITH COMPUTER EQUIPMENT THAT REQUIRES INSTALLATION AND CONFIGURATION.
