A variable can be made constant only with the help of a final keyword. If you want to make it to be accessible from other classes then you need static.

1.constant values can be declared  by using the   final keyword.
2.final  variables should be intialized.
3.final variable cannot be reintialized  once intialized the value.
4.final reference variables cannot refer to a different object  once the object 
    hasbeen assigned to the final variable.
5.final reference variables must be initialized before the constructor completes.

Final values must be initialized ..

This is partly true.. You can have blank final variables. which may not be initailized during declaration . They have to be initialized once and only once in constructor.

For declaring constant in Java,  Java gives us 3 suggestion.

1. Declare constant variable as a final.
2. Also constant variable declare as a final.
3. All the letter of constant variable is capital.

For example Maths. PI is a final static constant.It is a built in constant reside in java.lang package.
These 3 are only suggestion not a rule, it means Java not fores to you for applying.
