In this blog, we will discuss on instance variable. Variable has many types like final, static, const and instance. This all are declare in class body. So we can say properties of class.
Here we will see how to access instance variable from main class.
Let’s see example on instance variable.
class B // Class
int x,y; // instance variable [ class variable ]
public static void main(String args)
Scanner in1 = new Scanner(System.in);
B obj = new B(); // Create obj as object
System.out.print(“Enter X : ”);
obj.x = in1.nextInt(); // instance variables have to access from object
System.out.print(“Enter Y : ”);
obj.y = in1.nextInt();
if(obj.x > obj.y)
System.out.println(“X is Max”);
System.out.println(“Y is Max”);
Enter X: 56
Enter Y: 67
Y is Max
In this example, we can see instance variables x and y can access from main class using of class object.
Simple Class Examples
|1||Declare one array in Class and create ascending order of that array in main class|
|2||Declare 6 subject variable in Subject class and find total and percentage in main class|
|3||Create Employee class with EmpNo, Name , address , BasicSal , SaleAmount and netsalary instance variable. Display all data in main class. Netsalary = [BasicSal + SaleAmount*15%]|
