Triangle Class<\/strong><\/h3>\nIn this tutorial, We will use BlueJ Editor to code the Triangle class. The Main class is the driver. It instantiates the Triangle class. The Triangle class determines the triangle type and prints the result on the console.<\/p>\n

Main Class<\/h3>\n
This is driver class with the main method.<\/p>\n
public class Main {\r\n\r\npublic static void main(String[] args) {\r\n Triangle triangle = new Triangle(6, 8, 8);\r\n System.out.println(\"Given Triangle type:\"+ triangle.findTriangleType());\r\n }\r\n\r\n}<\/pre>\n <\/p>\n
Compile and run the program. Using BlueJ IDE, you can even inspect the object and execute the methods on the objects interactively.<\/p>\n
Inspecting the Triangle class\/object.<\/h3>\n
Once you have written the class, you can choose Inspect menu option to inspect the class. Right click on the Triangle class >> Inspect option.<\/p>\n
