oops practice program:

Expected Understanding: Access Modifiers, Single Inheritance, getter methods, Constructor Overloading
1) Create a Class named “Trainer”.
– Have default instance variables String dept, institute
– Have private instance variable int salary
– Assign 10000 as value for salary.
– Create getter method for salary.
– Assign values – “Java”, “Payilagam” to them
– Have instance method training() with void as return data type
– Add a print statement inside training() method
– Have instance named as ‘trainerKumar’ and pass “CSE”, “payilagam” as arguments to it.
– Handle above line with matching Constructor.

public class Trainer 
{
	String dept,institute;
	private int salary=1000;

	public Trainer()
	{
		System.out.println("hi");
	}

	public int get_salary()
	{
		return salary;
	}
	public Trainer(String dept,String institute)
	{
		this.dept=dept;
		this.institute=institute;
		System.out.println("dept" + this.dept + "institute" + this.institute);
	}
	public void training(String dept,String institue)
	{
		this.dept=dept;
		this.institute=institue;
		System.out.println("dept" + this.dept + "institue" + this.institute);
	}

2) Create a sub class “SQLTrainer” under “Trainer”.
– Have main method in it.
– Create instance ram for this class
– Handle with proper super class constructor
– Access parent class instance variables
– Call parent class instance method training()
– Access salary using getter method in parent class

public class SQLTrainer extends Trainer
{
	public SQLTrainer()
	{
		super();
	
	}
	public static void main(String[] args) 
	{
		SQLTrainer ram = new SQLTrainer();
		ram.training("java","payilagam");
		System.out.println(ram.get_salary());
		
	}

}
