Constructor help

i have create a constructor program and I ma having some trouble. im at step #2 on this project found at this webpage.
www.shsu.edu/~csc_tjm/cs146/Lab2.doc

if someone could help me figure out how to make the constructor for this program it would be greatly appreciated. Here is the code of the file that goes with the one I have to create



public class TelevisionDemo
{
public static void main(String[] args)
{
//create a Scanner object to read from the keyboard
Scanner keyboard = new Scanner (System.in);

//declare variables
int station; //the user's channel choice

//declare and instatiate a television object
Television bigScreen = new Television("Toshiba" , 55);
//turn the power on
bigScreen.power();
//display the state of the television
System.out.println("A " + bigScreen.getScreenSize() +
bigScreen.getManufacturer() +" has been turned on.");
//prompt the user for input and store into station

System.out.println("What channel do you want? ");
station = keyboard.nextInt();

//change the channel on the television
bigScreen.setChannel(station);
//display the current channel and volume of the television
System.out.println("Channel: " + bigScreen.getChannel() +
" Volume: " + bigScreen.getVolume());
System.out.println("Too loud!! I am lowering the volume.");
//decrease the volume of the television
bigScreen.decreaseVolume();
bigScreen.decreaseVolume();
bigScreen.decreaseVolume();
bigScreen.decreaseVolume();
bigScreen.decreaseVolume();
bigScreen.decreaseVolume();
//display the current channel and volume of the television
System.out.println("Channel: " + bigScreen.getChannel() +
" Volume: " + bigScreen.getVolume());
System.out.println(); //for a blank line


}
}

any help with this would be appreciated.
