Exercise 0        Name __________________        Score __/8

Use BlueJ and the editor to find out the answers:

1. What is the name of the Triangle class?
   
   Triangle
    
2. Give the Java code to create two Triangle objects named t1 and t2.
   
   Triangle t1 = new Triangle();
   Triangle t2 = new Triangle();
   
    
3. How many fields are there in a Triangle object?
   
   6
    
4. What is the default color of a Triangle?
   
   "green"
    
5. How many methods are there in a Triangle object?
   
   12
    
6. Give the one line of Java code to:
   1. use the erase method on t1 Triangle object.
      
      t1.erase();
      
      is the obvious answer but... because erase() is private:
      
          private void erase()
      
      cannot use outside the Triangle class definition nor does erase() appear on the list of Triangle methods in BlueJ.
       
   2. move t2 Triangle object vertically a distance of 20.
      
      t2.moveVertical(20);
       
   3. change the color of t2 Triangle object.
      
      t2.changeColor("red");
