Java program to print greatest number

Java Program to Find Largest Between Three Numbers Using Ternary Operator

In this program ternary operator (?, >, : ) to find the largest number as the output is used. The below program taking three numbers from the user and checked it with the ternary operator and print the greatest among the three numbers.
import java.io.*;

public class GreatestNumberUsingTernary

 {

    public static void main(String[] args)

    {           

        Int a,b,c;

        InputStreamReader in = new InputStreamReader(System.in);

        BufferedReader br = new BufferedReader(in);

        System.out.println("Enter three numbers to find greatest : ");

        // Inputing three number from the user 

        a  =  Integer.parseInt(br.readLine());

        b  =  Integer.parseInt(br.readLine());

        c  =  Integer.parseInt(br.readLine());    

        d = c > (a > b ? a : b) ? c : ((a > b) ? a : b);

        System.out.println("Greatest Number:"+d);

    }

}

Write a program to input three numbers and find the greatest of them.

In the following, we are taking three numbers from users as input and checked the number using if..else if statement and compiled and successfully print the output. We have given a simple description of the variable too.

Solution

import java.io.*;

public class GreatestNumber

{

    // main method begins

    public static void main (String args[]) throws IOException

    {

        int number1, number2, number3;

        number1 = number2 = number3 = 0;

       

        InputStreamReader in = new InputStreamReader(System.in);

        BufferedReader br = new BufferedReader(in);

        System.out.println("Enter three numbers to find greatest : ");

        // Waiting for the user input

        number1  =  Integer.parseInt(br.readLine());

        number2  =  Integer.parseInt(br.readLine());

        number3  =  Integer.parseInt(br.readLine());

      // Checking number1 with number2 and number1 with number3
      // if satisfied then print number1 as greatest.

       if (number1 > number2  &&  number1 > number3)

        {

            System.out.println (number1 +  " is greatest");

        }
       // Checking number2 with number1 and number2 with number3
       // if satisfied then print number3 as greatest.

        else if (number2 > number1  && number2 > number3)

        {

            System.out.println (number2 +  " is the greatest");

        }
      // if above condition is not satisefied the it print number3

        else

        {

             System.out.println (number3 +  " is the greatest");

        }

    } // end method main

} // end class

Sample Output

Enter three numbers to find the greatest : 

9

2

5

9 is the greatest

Enter three numbers to find the greatest : 

10

30

13

30 is the greatest

ISC 2016 COMPUTER PRACTICAL QUESTION 3 SOLVED

ISC 2016 COMPUTER PRACTICAL QUESTION 3 SOLVED

Write a program to accept a sentence which may be terminated by either '.', '?', or '!' only. The words may be separated by more than one blank space and are in UPPER CASE.

Perform the following tasks:

(a) Find the number of words beginning and ending with a vowel.

(b) Place the words which begin and end with a vowel at the beginning, following by the remaining words as they occur in the sentence.

Test your program with the sample data and some random data:

Example 1

Input : ANAMIKA AND SUSAN ARE NEVER GOING TO QUARREL ANYMORE.

Output : NUMBER OF WORDS BEGINNING AND ENDING WITH A VOWEL = 3

ANAMIKA ARE ANYMORE AND SUSAN NEVER GOING TO QUARREL

Example 2

Input : YOU MUST AIM TO BE A BETTER PERSON TOMORROW THAN YOU ARE TODAY

Output : NUMBER OF WORDS BEGINNING AND ENDING WITH A VOWEL = 2

A ARE YOU MUST AIM TO BE BETTER PERSON TOMORROW THAN YOU TODAY

Sample Output:

Enter a sentence:

ANAMIKA AND SUSAN ARE NEVER GOING TO QUARREL ANYMORE

ANAMIKA

ARE

ANYMORE

Total Words Begin and End with Vowels=3

Words Begin and End with Vowels

ANAMIKA

ARE

ANYMORE

Words Begin and End without Vowels

AND

SUSAN

NEVER

GOING

TO

QUARREL

Enter a sentence:

HAVE A NICE DAY ANA.

A

ANA

Total Words Begin and End with Vowels=2

Words Begin and End with Vowels

A

ANA
