Java program

The following is the data type class Triangle that is defined to hold the information of a triangle and some actions access those information. However, the class Triangle is not complete yet.

public class Triangle {

//A. ........
priviate double base; private double height;

//B. no-argument constructor

//C. parameter constructor

//D.method calculate area of triangle

//E. method toString to create the string output of a triangle }

In a word document, provide the answers of the following questions:

1.What is the name to call lines listed in a. Select good answers:

2.Provide the code of no-argument constructor, parameter constructor

3.Provide the code of mutator methods and accessor methods of variables, base and heigh

4.Provide the code to calculate and return the area of a triangle

Provide the code to create the output of a triangle as below if its base = 6.5 and height = 5.25

TRIANGLE Base = 6.5 Height = 5.25 Area = 34.125

Explanation / Answer

public class Triangle { //A. ........ private double base; private double height; //B. no-argument constructor public Triangle() { height = 0; base = 0; } //C. parameter constructor public Triangle(double base, double height) { this.base = base; this.height = height; } //D.method calculate area of triangle public double area() { return base * height; } //E. method toString to create the string output of a triangle @Override public String toString() { return "TRIANGLE Base = " + base + " Height = " + height + " Area = " + area(); } public static void main(String[] args) { Triangle triangle = new Triangle(6.5, 5.25); System.out.println(triangle); } }
