Using the following UML, create a class called SlotMachine that simulates a casino slot machine in which three numbers between 0 and 9 are randomly selected and printed side by side. This is done using the “pullLever” method which is overloaded, a default method which uses one token, and a parameter method which can specify how many tokens to gamble for that single pull. There are five situations which occur when the lever is pulled.

1) {0,0,0} Super Jackpot, all zeros. Token input is multiplied by a factor of 500 and added to the machine token credit. Should output suitable “Super Jackpot Winner” message showing winnings.

2) {X,X,X} Three number win. Where X is a value 1-9, token input is multiplied by a factor of 50 and added to the machine token credit. Should output suitable “Jackpot Winner” message showing winnings.

3) {X,X,Z} Free spin. Where X and Z are…

Java code to convert XML TO XSLT

 import java.io.*; 
 import javax.xml.transform.*; 
 import javax.xml.transform.stream.*;
  
public class Driver {

    public static void main(String[] args)
    {
        try
        {
            TransformerFactory tFactory = TransformerFactory.newInstance();

            Source xslDoc = new StreamSource("datasheet.xsl");
            Source xmlDoc = new StreamSource("datasheet.xml");

            String outputFileName = "datasheet.html";
            OutputStream htmlFile = new FileOutputStream(outputFileName);

            Transformer transformer = tFactory.newTransformer(xslDoc);
            transformer.transform(xmlDoc, new StreamResult(htmlFile));
        }
        catch(Exception e)
        {
            e.printStackTrace();
        }
    }
}

You can set Precision for double value either via BigDecimal or DecimalFormat, depending on what you want to do with the value later.

1. Setting double precision using DecimalFormat

DecimalFormatExample.java

package com.codersarts;

import java.text.DecimalFormat;

public class DecimalFormatExample {

   // setting precision upto 2 decimal point
    private static DecimalFormat df = new DecimalFormat("#.##");

    public static void main(String[] args) {

        double piValue = 3.14159265359;
        System.out.println("double : " + piValue);
        System.out.println("double : " + df.format(piValue));    //3.14

    }

}

Output

Yes, you can add as many function you wish .

A Java Enum is a special Java class that define group of constants which is unchangeable variables, like final variables. An enum can contain constants, methods etc. Java enums were added in Java 5.

To create an enum, use the enum keyword and separate the constants with a comma.

Note that they should be in uppercase letters:

Example 1: enum for movie RATING

enum RATING {
         GENERAL,
         PARENTGUIDANCE,
         MATURE
}
