Thread: Printing data from a method

I am trying to make a program that will get the area of a Triangle,Rectangle,Circle.

The user picks which shape they want the area of and then inputs the Length/Width/Radius or whatever is needed. Im now stuck. I cannot get the data to print. I have made all the equations in the code. Here is the code.

import java.util.Scanner;
public class area {
 
 
    public static void main(String[] args) 
    {
        //Declaring Variables.
        int triHeight, triBase, lengthRect, widthRect, shapeNum;
        double circRadi;
 
        Scanner reader = new Scanner (System.in);
 
        //Receiving Input
        System.out.println ("Which shape do you want area for?");
        System.out.println("1 Triangle 2 Circle 3 Rectangle 0 None");
        shapeNum = reader.nextInt ();
        if (shapeNum == 1) {
            System.out.println("Base of triangle?");
            triBase = reader.nextInt ();
            System.out.println("Height of triangle");
            triHeight = reader.nextInt ();
 
         }
        if (shapeNum == 2) {
            System.out.println("Radius of circle?");
            circRadi = reader.nextDouble ();
        }
        if (shapeNum == 3) {
            System.out.println ("Length of rectangle?");
            lengthRect = reader.nextInt ();
            System.out.println("Width of rectangle?");
            widthRect = reader.nextInt ();
 
        }
 
 
 
 
    }
    public static void areaTriangle(int triBase,int triHeight, int triOutput) {
        triOutput = (triBase*triHeight)/2;
 
    }
 
    public static void areaCircle (double circOutput,int circRadi ) {
        circOutput = (circRadi*Math.PI);
    }
 
    public static void areaRectangle(int rectOutput, int lengthRect, int widthRect) {
        rectOutput = lengthRect*widthRect;
    }
 
 
 
}

The code you posted doesn't have anything to do with the problem you asked about.

What is shown on the console when you execute the program? Please copy the full contents of the console and paste it here showing what was typed in and what was printed.

Where does the code print out any of the results of the computations?

Comments on the code:
When you have a bunch of mutually exclusive choices (only one can be true)
Use an if/else if/else chain for the tests. The ending else to catch an error if none of the above were true.

Also look at using a switch() statement for this type of selection. Be sure to add a default: case to catch any error.



Is this the same question: http://www.javaprogrammingforums.com...html#post76168

how to display those results.

Use println() statements. You've done it in this thread:

To print the results in the main() method, the methods would have to return the results.
What does the assignment say the program should do?

I didn't ask to see your assignment, I asked you if the assignment required how the code be written.
You need to understand your assignment and if you have a question about your assignment, you should ask it.
