Create the classRightTrianglewhich implements the API exactly as described in the followingJavadoc(Links to an external site.)

Use thePythagorean theorem(Links to an external site.)

To find the hypotenuse (and therefore the perimeter) of a right triangle. It can be find the area of a right triangle by multiplying the base and height together, then dividing this product by 2.

Use the runner_RightTriangle file to test the methods in the class; do not add a main method to the RightTriangle class.

The documentation only shows public methods, variables and constructors. It need to add some private member variables to the RightTriangle class to store the necessary information. Think carefully about what information actually needs to be stored and how this will need to be updated when methods change the state of a RightTriangle object.

Source codes:

public static void main(String[] args){

Scanner scan = new Scanner(System.in);

RightTriangle t = new RightTriangle();

String instruction = "";

while(!instruction.equals("q")){

instruction = scan.nextLine();

if(instruction.equals("getArea")){

System.out.println(t.getArea());

}

else if(instruction.equals("getBase")){

System.out.println(t.getBase());

}
