Question

in java

Write a class named “Stock” to model a stock. The properties and methods of the class are shown in figure below. The method “ percentage ” computes the percentage of the change of the current price vs the previous closing price. Write a program to test the “Stock” class. In the program, create a Stock object with the stock symbol SUND, name Sun Microsystem V, previous closing price of 100. Set a new current price randomly and display the price percentage.

Stock

private String symbol
private String name
private double previousClosingPrice

private double currentPrice
public Stock()
public Stock(String symbol, String name)

public String getSymbol()
public String getName()
public double getPreviousClosingPrice()
public double getCurrentPrice()
public void setSymbol(String symbol)
public void setName(String name)
public void setPreviousClosingPrice(double price)
public void setCurrentPrice(double price)
public double percentage()

Note: Could you plz go through this code and let me know if u need any changes in this.Thank You
=================================

// Stock.java

public class Stock {
   // Declaring variables
   private String symbol;
   private String name;
   private double previousClosingPrice;
   private double currentPrice;

   // Parameterized constructor
   public Stock(String symbol, String name) {
       this.symbol = symbol;
       this.name = name;
   }

   // Setters and getters
   public String getSymbol() {
       return symbol;
   }

   public void setSymbol(String symbol) {
       this.symbol = symbol;
   }

   public String getName() {
       return name;
   }

   public void setName(String name) {
       this.name = name;
   }

   public double getPreviousClosingPrice() {
       return previousClosingPrice;
   }

   public void setPreviousClosingPrice(double previousClosingPrice) {
       this.previousClosingPrice = previousClosingPrice;
   }

   public double getCurrentPrice() {
       return currentPrice;
   }

   // This method will find the change in percentage
   double percentage() {
       return ((currentPrice - previousClosingPrice) / previousClosingPrice) * 100;
   }

   public void setCurrentPrice(double currentPrice) {
       this.currentPrice = currentPrice;
   }

}

==========================================

// Test.java

public class Test {

   public static void main(String[] args) {
double currentPrice=0.0;
  
       Stock s=new Stock("SUND","Sun Microsystem V");
       s.setPreviousClosingPrice(100);
       currentPrice=(Math.random() * (101)) + 100;
       s.setCurrentPrice(currentPrice);
      
       System.out.printf("Price Percentage : %.2f%%\n",s.percentage());

   }

}
