Java Math

Question

I have an assignment due tomorrow to create a stock market screen. It is suppose to display the stock symbol, purchase price, number of shares, the current stock price, and then calculate the following worth bought gain/loss. I do not have a clue were to start. If anyone could help, please do feel free to e-mail me any comments. Thank you in advance. It seems the instructor is overloaded with others asking questions.
P.S. there should be at least nine methods for this class.

Answer 1

public class Stock
     //Instance variables
     public String price;
     public String shares;
     public String numOfShares;
     public long val;
     public Stock(String price)
          this.price = price;
          //count = + 1
//          count ++; //increments the variable count
//          counter++; //increment the class variable counter
     public String toString()
     //Default Constructor
     //public String toString()
     String str = "The price is:"+ price +" \tand the shares is:" + shares +" \tand the number of shares is " + numOfShares;
          return str;
          price = "36 ";
          //Parameterized Constructor
          public Stock(String pr,String sh,String num,long val)
          //set some default values for the instance variables
          price = "pr";
          shares = "sh";
          numOfShares = "num";
          generateval();
     public void setPrice(String pr)
     public void setShares(String sh)
     public void numOfShares(String num)
//this will generate a value number useing theMath.random() method
     public void generateval()
     val =(long)(Math.random() * 100 + 1);
               Stock pr = new Stock ("price of stock");
               System.out.println(pr.toString());
               Stock sh = new Stock("price of shares");
               System.out.println(sh.toString());
               Stock num = new Stock("number of shares");
               System.out.println(num.toString());
                         pr.toString();
                         sh.toString();
                         num.toString();
     public String getPrice()
          //price
          return price;
     public String getShares()
          //shares
          return shares;
     public String numOfShares()
          return numOfShares;
     public float getval()
          return val;
} //end of class
