Write a program to find greatest of three number using conditional operator in java?

Answer 1

import java.util.Scanner;

class LargestOfThreeNumbers

{

public static void main(String args[])

{

int x, y, z;

System.out.println("Enter three integers ");

Scanner in = new Scanner(System.in);

x = in.nextInt();

y = in.nextInt();

z = in.nextInt();

if ( x > y && x > z )

System.out.println("First number is largest.");

else if ( y > x && y > z )

System.out.println("Second number is largest.");

else if ( z > x && z > y )

System.out.println("Third number is largest.");

else

System.out.println("Entered numbers are not distinct.");

}

}

Answer 2

Get the greatest of the first two numbers. Then get the greatest of the result and the third number.

result = a > b ? a : b;

result = result > c ? result : c;

This can be combined into a single line, but that would involve too much repetition.

Answer 3

Use the following function:

int largest_of_3 (int a, int b, int c) {

if (a>b && a>c)

return a;

else if (b>c)

return b;

else

return c;

}

Of course it would be much easier to implement such a function using a more primitive function, returning the largest of two values:

int largest (int a, int b) {

if (a>b) return a;

else

return b;

}

Given this function, the largest of three function becomes:

int largest_of_3 (int a, int b, int c) { return largest (largest (a, b), c);

}
