Creating class and Object

Here you can see how class and object are created.
class Emp  
{
    int empno;  //Instance variables
	String name;
	float sal;

	void input(int eno,String ename,float esal)   //Methods
	{
		empno=empno;
		name=ename;
		sal=esal;
	}
	void show()
	{
		System.out.println("Empno is"+empno);
		System.out.println("Name is "+name);
		System.out.println("Sal is "+sal);
	}
	public static void main(String args[])
	{
		Emp ram=new Emp();  //Creating a new object, a new operator is used to 
		allocate a memory for the object.
		//ram is an object of Class Emp.
		ram.input(1001,"Ram ", 9090.0f);
		ram.show();
		Emp shyam =new Emp();
		shyam.input(1002,"Shyam",8888.0f); 
		shyam.show();
	}
}
