difference between void and non void methods in java

1-void : does not return any value. 
2  The "void" return type means that
3  this method doesn't have a return type.
4	In an application, this approach
5    may be used to print runtime 
6    specific messages on the console. Exp: "setter" in encapsulation.
7	
8	-non-void: MUST return a Value.
9      (Data type needs to be same with return-type)
10	This means that you can use the 
11    returned value in your code for 
12      further processing. I guess good 
13      examples of such methods 
14      are "getter" in encapsulation.
