For a boolean field, what is the naming convention for its getter/setter?

Suppose you have

boolean active;

Accessors method would be

public boolean isActive(){return this.active;}

public void setActive(boolean active){this.active = active;}

  1. is prefix should be used for boolean variables and methods.

    isSet, isVisible, isFinished, isFound, isOpen

This is the naming convention for boolean methods and variables used by Sun for the Java core packages. Using the is prefix solves a common problem of choosing bad boolean names like status or flag. isStatus or isFlag simply doesn't fit, and the programmer is forced to chose more meaningful names.

Setter methods for boolean variables must have set prefix as in:

void setFound(boolean isFound);

There are a few alternatives to the is prefix that fits better in some situations. These are has, can and should prefixes:

boolean hasLicense(); 
boolean canEvaluate(); 
boolean shouldAbort = false;
