I'm creating a program that caluclates the area of a triangle & rectangle

Question

Hi. I am reposting this topic in order to post it correctly. I will begin with my questions. I am to ask user to enter either rectangle or triangle to find the area of shape or to hit X to terminate the program. Have I coded this correctly? I am to use while and if loops which calls methods from CalculateAreaOfShapes. I have not attempted the if loops because I'm just not sure how to do them. If someone could give me some suggestions I'd apppreciate it. Next, if user enters Rectangle, I am to call calculateAreaOfRectangle() Have I coded this correctly? Also, If user enter Triangle, I am to call calculateAreaOfTriangle() Have I coded this correctly? The program should not terminate until X is entered. My code goes as follows:
import java.util.Scanner;
public class ModifiedTestCalculateAreaOfShapes
     public static void main(String[] args);
          Student Royce = new Student();
          //call student class's print method from student
          Royce.printMyInfo();
          //Welcome to Royce's modified TestCalculaterAreaOfShapes Program!
          System.out.println("Welcome to the Royce ModifiedTestCalculate area program");
          System.out.println("Please enter t to calculate area of triangle or r rectangle");
         //create a Scanner object name sc
          Scanner sc = new Scanner(System.in);
         //modifing this assignment so that the user has a choice until choice isn't equal to "r" or "R", or "t" or "T".
         String choice = ("y");   //Declare the variable to hold the name
         while(!choice.equalsIgnoreCase ("x"));   //Begin program loop
              //get the users choice "t" or "r"
               System.out.print ("Enter (t/r): ");
               String user = sc.next();
                System.out.print("Enter shape: ");
                double shape = sc.nextShape();
                System out.println("Please enter t to calculate area of triangle, r for recctangle or x to quit\n")
                //Asking the user to make a choice.
                          //create a Scanner object for if statements/
                          if(choice1.equals("t"))  //If choice is t then call calculateAreaOfShapes for my code
                                          //calculate the area of a Rectangle and a Triangle
                                        CalculateAreaOfShape.Shapes = new CalculateAreaOfShapes();
                                        double TriangleArea = Shapes.calculateAreaOfTriangle(height*base)/2
                                        else if(choice1.equals("r"));
                                                  double RectangleArea = Shapes.calculateAreaOfRectangle(height,width);
                         //display the area for each
                         String message = "Area for triangle: " + areafortriangle + "\n"
                                           + "Area for rectangle:" + areaforrectangle + "\n"
                                           + "Total area:        " + total + "\n";
                         System.out.println(message);
                         //see if the user wants to continue
                         System.out.print(Continue? (r/t): "){code}
