Code Convention issue

[Raghda Ismail]

Hi every body,

I was reading code conventions from java.sun and i read these two lines and i really cannot understand them

Numerical constants (literals) should not be coded directly, except for -1, 0, and 1, which can
appear in a for loop as counter values.

i need to follow java standards in my current application and its important to me to understand it.

any help is appreciated.

Thanks in advance

Declare them as a constant and use.
example:-
public static final int LEVEL_ERROR = 3;
Create constant class and define required constants in it.
General: Constant Classes
