Question

IN JAVA

1. Write up a small program that accepts two integers from the user. Print which of the two values is bigger. If they are the same, print that they are the same.

2. Write a method that accepts three doubles. Calculate and return the average of the three passed double values.

3. Write up a method that accepts a score between 0-10. Print out a message according to the following table. You ay personally decide the boundaries. i.e., a 3 may be either no bueno or average, up to you.

0-3: No bueno

3-5: Average

5-7: Okay

7-10: Great

4. Write a program to read in a user value as an integer. also read in a string from the user. Print the string as many times as the integer value. That is, if the user enters 3 and the string "dog", print out DogDogDog.

5. Write a class that represents a Pizza. Include two data fields to represent the toppings and cost. Include a constructor to create the pizza. Include a method to print the cost of the pizza.

Answer 1

Question 1:
Write up a small program that accepts two integers from the user. Print which of the two values is bigger. If they are the same, print that they are the same.
Code:
import java.util.Scanner;

public class BiggestNumber
{
   public static void main(String[] args)
   {
       Scanner src=new Scanner(System.in);
      
       //Accepts two integers from the user.
       int a=src.nextInt();
       int b=src.nextInt();
      
       //Print which of the two values is bigger. If they are the same
       if(a>b)
           System.out.println(a+" is greater than "+b);
       else if(a<b)
           System.out.println(a+" is less than "+b);
       //print that they are the same.
       else
           System.out.println("Both the numbers are same");
   }
}

Question 2:
Write a method that accepts three doubles. Calculate and return the average of the three passed double values.
Code:
public static double AverageOfThree(double a,double b,double c)
   {
       return (a+b+c)/3.0;
   }

Question 3:
Write up a method that accepts a score between 0-10. Print out a message according to the following table. You ay personally decide the boundaries. i.e., a 3 may be either no bueno or average, up to you.
Code:
public static void PrintBoundaries(int number)
   {
       if(number>=0 && number<=3)
           System.out.println("No bueno");
       else if(number>3 && number<=5)
           System.out.println("Average");
       else if(number>5 && number<=7)
           System.out.println("Okay");
       else if(number>7 && number<=10)
           System.out.println("Great");
   }

Question 4:
Write a program to read in a user value as an integer. also read in a string from the user. Print the string as many times as the integer value. That is, if the user enters 3 and the string "dog", print out DogDogDog.
Code:

import java.util.Scanner;

public class PrintName
{
   public static void main(String[] args)
   {
       Scanner src=new Scanner(System.in);
      
       //Write a program to read in a user value as an integer.
       String str=src.next();
      
       //also read in a string from the user. Print the string as many times as the integer value.
       int count=src.nextInt();
      
       //Capitalize the first char
       String Newstr=(str.charAt(0)+"").toUpperCase()+str.substring(1, str.length());
      
       //print out the string 3 times repeated
       for(int i=0;i<3;i++)
           System.out.print(Newstr+"");
   }
}
Question 5:
Write a class that represents a Pizza. Include two data fields to represent the toppings and cost. Include a constructor to create the pizza. Include a method to print the cost of the pizza.
Code:
//Write a class that represents a Pizza
public class Pizza
{
   //nclude two data fields to represent the toppings and cost.
   static String toppings;
   static double cost;
  
   //Include a constructor to create the pizza.
   Pizza(String toppings,double cost)
   {
       this.toppings=toppings;
       this.cost=cost;
   }
  
   //Include a method to print the cost of the pizza.
   public static void PrintCost()
   {
       System.out.println("The cost of the pizza is "+cost);
   }  
}
