Problem with the Drawstring method

#
I wrote the following code:
public void drawVitals(){
drawString(health, 1, 1); 
}
But when i run it, it gives the following error: Cannot find symbol - method drawString(int, int, int) Are there any imports i need? Is there a special Greenfoot only method i can use to do this? Thanks!

You drawString is a method of GreenfootImage! This will work: getImage().drawString(...);

Did that, got a new error: 
drawString(java.lang.String, int, int) in greenfoot.GreenFootImage cannot be applied to (int, int, int)
I think i know the problem, health is an int, not a string :O How do i transfer an int to a string? Nevermind figured it out

Well, thats very easy, just write getImage(""+health, ...); The ""+int transfers it into a String

health_string = Integer.toString(health); //make an integer copy of health
getImage().clear(); //erase current image
getImage().drawString(health_string, 0, 1); //update image
