Here is the format of the method header we use in this class for the three kinds of methods in Java, giving information about calls on each kind of method, with a few notes below: Is a statement. Is an expression, which yields a value. Appears in a new-expression or as the first statement of a constructor.

To call a method in Java, write the method's name followed by two parentheses () and a semicolon; In the following example, myMethod() is used to print a text (the action), when it is called:

You can write a method header with just a few simple steps. Choose public or private; Choose what the method returns: void (nothing), int**,** double**,** boolean**,** String, or the name of a class; Choose the name of the method; Choose what parameters to pass into the method; That's it! You're ready to start writing your own method headers! 👏

Methods are essential building blocks in Java, used to define the behaviors of objects. Understanding the method header and method signature helps in writing clear and effective code. Accessors (getters) and Mutators (setters) are methods that …

For example, you could write void foo(Collection<String> strs) { String bar = ""; } (which compiles), but you could also write <String> void foo(Collection<String> strs) { String bar = ""; } which does not, since String is a type variable, not java.util.String.
