Question

JAVA

1.

Inherit a class

Create a class called Overtime that inherits from SportsGame. Add the following fields (Boolean suddenDeath, int minutes). Override the toString, and constructors. Create the setters and getters. Instantiate and call in a main.

2.

Exceptions and loop

At the console, create a program that asks the user for a number between 1 and 100. The routing should be idiot proof. It should catch ay exceptions and continue to ask until the user correctly enters the a valid number.

3.

Read and parse the books.xml file. Display in an attractive format the author, title, genre, and price. The books file was borrowed from https://msdn.microsoft.com/en-us/library/ms762271(v=vs.85).aspx.

Explanation / Answer

//Java code for question 1

import java.io.*;
import java.util.*;
interface SportGame
{
   public String toString();
}
public class Overtime implements SportGame
{
   int minute;
   boolean suddenDeath;
   public Overtime()
   {
       minute=0;
       suddenDeath=false;
   }
   //Getter methods
   public int getMinute()
   {
       return minute;
   }
   public boolean getSuddenDeath()
   {
       return suddenDeath;
   }
   //Setter methods
   public void setMinute(int m)
   {
       minute=m;
   }
   public void setSuddenDeath(boolean t)
   {
       suddenDeath=t;
   }
   //Overriding toString method
   public String toString()
   {
       return minute+" "+suddenDeath;
   }
   public static void main(String args[])
   {
       //Instantiating Overtime class and calling its methods and displaying results
       Overtime o=new Overtime();
       o.setMinute(10);
       o.setSuddenDeath(true);
       System.out.println(o.toString());
   }
}

Output :

10 true

//Java code for 2nd question

import java.io.*;
import java.util.*;

public class Valid
{
   public static void main(String args[])
   {
       int t;
       Scanner s=new Scanner(System.in);

       while(true)
       {
       try
       {
           System.out.println("Enter the number between 1 and 100 :");
               t=s.nextInt();
               if(t<1 || t>100)
                   throw new Exception();
               else break;
          
       }
       catch(Exception e)
       {
           System.out.println("Invalid input -Please enter valid input");
       }
       }
   }
}

//Output :

Enter the number between 1 and 100 :
124321
