Methods and Attributes

METHODS.- The method has a pair of keys , among which is the code that will be executed

when the function call .

ATTRIBUTES.- Determine a storage structure for each class object

EJERCICIO.-

public class person { private String name; public void setearName (String value) { name=value; } public void getName() { System.out.println(name); } }

Instance Variables, Class Variables and Local variables

Local variables.- those are that can be used anywhere in the program.

Class Variables.- is typical of the class that contains.

Instance Variables.- are used to define the attributes of an object.

public class student { private String name; private String surnameFather; private String surnameMother; private int age; public String specialty; int totaltelephone=0; String [] numbertelephono; public int averagePrevious; public int course; public void setData1 (String espec,int proant,int course) { this.course=course; if(curso>=4) { specialty =spec; averagePrevious =aver; } else{ averagePrevious =aver; } } public void setdataFamily(String name,String surnameFather,String surnameMother,int age) { this.name=name; this.surnamFather=surnameFather; this.surnameMother=surnameMother; this.age=age; } public void setTelephone(String Number) { totaltelephone++; numberTelephone=new String[numberTelephone]; numberTelephone [numberTelephone -1]=Number; }

public void Data() { System.out.println(course); System.out.println(averagePrevious); System.out.println(specialty); System.out.println(name); System.out.println(surnameFather); System.out.println(surnameMother); System.out.println(age); } }
