Boilerplate

// Abstract class
abstract class Sunstar {
	private int a;
	public Sunstar(int a){
		this.a = a;
	}
    abstract void printInfo();
}
 
// Abstraction performed using extends
class Employee extends Sunstar {
    void printInfo()
    {
        String name = "avinash";
        int age = 21;
        float salary = 222.2F;
 
        System.out.println(name);
        System.out.println(age);
        System.out.println(salary);
    }
}
