Use globally defined constants

You can use globally defined constants by defining them inside a class and referencing themwithout instantiation.

public class CONSTANT { public static final integer SUCCESS = 1; public static final integer FAILURE = -1; public static final integer NOTFOUND = 0; }

Since the members of the class are defined as "static", there is no need to instantiate the class. To use a constant, simply use CONSTANT.[constant name]

if (myMethod()==CONSTANT.SUCCESS) {
...;
}
else {
...;
}
