Instance Variables in Java
Instance variables in Java are fields declared within a class but outside any method. They are used to store unique data for each instance of the class1234. Unlike class variables (static variables), which are shared among all instances, instance variables have distinct values specific to each individual object. Here’s an example of instance variables in a class:
Instance variables
public class Car {
private String brand; // Instance variable
private String color; // Instance variable
}
In this example, brand and color are instance variables.
Instance Methods in Java
Instance methods in Java are methods that require an object of its class to be created before it can be called. They define the behavior of an instance and can access and manipulate the instance’s variables. Instance methods can be invoked on specific instances to perform operations related to that instance. Here’s an example of an instance method:
Instance methods
public class Car {
private String brand; // Instance variable
private String color; // Instance variable
public void startEngine() { // Instance method
// ...
}
}
In this example, startEngine is an instance method.
