Accessor Methods
Learn what an accessor method is and how to write one in Java.
What is an accessor method?
An accessor method allows other objects to obtain the value of instance variables or static
variables. It is a non-void method. A non-void method returns a single value. Its header includes the return type in place of the keyword void
. For example:
- A
boolean
method should return a variable of theboolean
type. - An
int
method should return a variable of theint
type. - A
float
method should return a variable of thefloat
type.
In non-void methods, a return expression’s compatibility with the return type is evaluated, and a copy of that value is returned. This is referred to as return by value.
