static vs final variables java code example

Example 1: private static final java

private final static -> create this variable only once.
private final -> create this variable for every object. 
  First one saves memory, go for it.

Example 2: final vs static keyword in java

The two really aren't similar. 
"STATIC" fields are fields that do not 
belong to any particular instance of a class.
and there is only one copy of the variable in memory
shared by all instances of the class.
On the other hand
"FINAL" The final keyword just means the value
can't be changed. Without final, any object can 
change the value of the variable
