Pa- rameters are values that the program passes after the method name inside a pair of paren- theses (lines 10, 14, 18, and 22). Since parameters must be declared, parameter passing also always follows the scheme data type identi\ufb01er, as in a declaration. In line 10 you can see that the class Person takes the parameter address. Then the program overwrites the internal value of the attribute of the same name with this.salutation = salu- tation.<\/p>\n

Because setter methods return none values, such methods are marked in Java with the keyword void. The keyword expresses that the return value is empty. In this way, setter methods are easily distinguished from getter methods, which must de\ufb01ne the data type of the return value at this point. They are equally easy to distinguish from constructors, which must not de\ufb01ne anything at this point.<\/p>\n

12.7.2 Usage Listing 12.16 shows the use of setter methods using the example of the program SetterDe- mo. The program creates a new person object named lukas using the default constructor. In lines 9 through 11, the program calls the setter methods of the person class to pass the object the desired values for the lukas object.<\/p>\n

Listing 12.16: The setter methods of the class \u00bbPerson\u00ab \/\/Examples\/Methods package programmingcourse; public class SetterDemo { public static void main(String[] arguments) { Person lukas = new Person(); 12 Methods lukas.setSalutation(Salutation.STUDENT); lukas.setFirstName(“Lukas”); lukas.setLastName(“Wittek”); lukas.setUniversity(“University of Mainz”); System.out.println(“Hi, I am ” + lukas.getFirstName() + “.”); System.out.print(“I am ” + lukas.getSalutation()); System.out.println(” at the \\n” + lukas.getUniversity() + “.”); } } Figure 12.18 shows what the program outputs.<\/p>\n

Hi, I am Lukas. I am student at the University of Mainz. Figure 12.18: Program output of the person object \u00bblukas\u00ab with its setter methods. 12.8 Summary In Java, there are several types of methods: constructors create objects, getter and setter methods query and modify values. Operations are structured like functions of a classi- cal programming language.<\/p>\n

With these methods one starts for example programs, accom- plishes computations or makes database inquiries. As with variables, Java distinguishes between instance and class methods. Instance meth- ods require an object to be executed. Getter and setter methods are examples of instance methods. In contrast, no object is necessary to execute class methods. They are introduced by the keyword static. The best-known static method is main(…), which is used to start a program. 12.9 Literature Java methods { \u0003\u0003\u0087\u0003Constructor } Java provides you with four types of methods: With the help of constructors you create objects.<\/p>\n

Getter and setter methods are used to query and modify attributes. Operations are used, for example, to perform calculations. Figure 12.19: Professor Roth summarizes the characteristics of Java methods.<\/p>\n
