What is an accessor?
An accessor is a method in a Java Bean that is used to access the private variables of the class. Usually instance variables in a bean are declared as private and they can be accessed only via these accessor methods. Ex: public class Employee { private String name = ""; private int age = 0; public String getName(){ return this.name; } public void setName(String nm){ this.name = nm; } public int getAge(){ return this.age; } public void setAge(int ag){ this.age = ag; } } In the above example name and age are instance variables and the methods beginning with get and set are the accessor methods.
What is class variable?
Class Variables or Instances variables are variables that are declared inside a class and are available for the whole class. They are available for all instances of that class and are not specific to any method. Ex: public class Test { private String name = "Rocky"; } Here name is a class variable.
Why is Javascript referred to as a loosely typed language?
This is because, unlike Java, all variables are declared without a type.var a = 7; // Integervar b = "A string"; // String variableYou might notice a difference between this and Java. Java goes like this:int a = 7; // IntegerString b = "A string"; // StringIf you want more information, try the related link below.
What are the variables in vb?
The variables is visual basic are the items being declared in order to use within the program, for example if you were writing a program for the SUVAT equations the variables would be difined as follows... Dim is as integer Dim iu as integer Dim iV as integer e.c.t Think of the Dim to mean declare and the "as integer" is the data type. If it was a text value (string) for example a name it would be declared as follows: Dim sname as string where sname is the variable. For an array of values you would do the same but as follows: dim sname(100) as string this would create a space so to speak for 101 (0-100) names which would be inputted as so: sname(0) = Dan sname(1) = Sarah e.c.t hope that helps without being to complicated

The variable will be declared and initialized within the method and the variable will be destroyed when the method has completed.Instance variables . Instance variables are variables within a class but outside any method. These variables are instantiated when the class is loaded. Instance variables can be accessed from inside any method, constructor or blocks of that particular class.Class variables . Class variables are variables declared with in a class, outside any method, with the static keyword.A class can have any number of methods to access the value of various kind of methods. In the above example, barking(), hungry() and sleeping() are variables.
