What Can You Put In The Body Of A Method Java

Method Announcement Elements

Chemical element	Function
accessLevel	(Optional) Admission level for the method
static	(Optional) Declares a grade method
abstract	(Optional) Indicates that the method is not implemented
final	(Optional) Indicates that the method cannot be overridden
native	(Optional) Indicates that the method is implemented in another linguistic communication
synchronized	(Optional) The method requires a monitor to run
returnType methodName	The method'south return type and name
( paramList )	The list of arguments to the method
throws exceptions	(Optional) The exceptions thrown by the method

Although a method name can be any legal identifier, lawmaking conventions restrict method names. In general, method names should be verbs and should be in mixed case, with the first letter in lowercase and the commencement letter of the alphabet of each internal give-and-take in uppercase. Here are some examples:

toString compareTo isDefined setX getX          

A method proper name should non be the same equally the class proper noun, considering constructors are named for the class. The JavaBeans architecture naming conventions further describe how to name methods for setting and getting backdrop.

Note:  Y'all should refer to Sun Microsystems' code conventions for the Coffee programming language and the JavaBeans architecture naming conventions outlined in the JavaBeans specification .

Typically, a method has a unique proper name within its course. Withal, three situations might cause a method to accept the same name as other methods in the form or in a superclass: overriding methods, hiding methods, and name overloading.

A method with the aforementioned signature and render type as a method in a superclass overrides or hides the superclass method. The department Overriding and Hiding Methods describes what each means, shows you how to override and to hide methods, and discusses related bug.

The Coffee programming language supports name overloading for methods, which means that multiple methods in the same course tin share the same name if they accept different parameter lists. Suppose that you have a class that can draw various types of information (strings, integers, and then on) and that contains a method for cartoon each data type. In other languages, you lot take to recall of a new proper name for each method, for example, drawString, drawInteger, drawFloat, and and so on. In the Java programming language, you lot tin can use the same name for all the drawing methods simply pass a different blazon of argument to each method. Thus, the data drawing course might declare three methods named draw, each of which takes a different type of argument.

public grade DataArtist {     ...     public void describe(Cord s) {         ...     }     public void draw(int i) {         ...     }     public void draw(float f) {         ...     } }          

Overloaded methods are differentiated past the number and the type of the arguments passed into the method. In the code sample, draw(String due south) and draw(int i) are distinct and unique methods because they require different statement types. Y'all cannot declare more than one method with the same proper name and the same number and type of arguments, considering the compiler cannot tell them autonomously. The compiler does not consider return type when differentiating methods, and so yous cannot declare two methods with the same signature fifty-fifty if they accept a different return type.
