Java Program to Find Greatest of Three Number: In Different Ways

Greatest of any three numbers using nested if:

User enter any three number and press enter button to show the greater number among the three number

import java.util.*;
class Greatest
{
 public static void main(String args[]) 
 {
  int a,b,c;
  Scanner rd = new Scanner(System.in);
  System.out.println("Enter three numbers : ");
  a = rd.nextInt();
  b = rd.nextInt();
  c = rd.nextInt();
  if(a>b)
  {
   if(a>c)
   {
    System.out.println( a+" is the greatest no.");
   }
   else 
   {
    System.out.println(c+" is the greatest no.");
   }
  }
  else
  { 
   if(b>c)
   {
    System.out.println(b+" is the greatest no.");
   }
   else
   {
    System.out.println(c+" is the greatest no.");
   }
  }
 }
}

Output:

Enter three numbers : 

25 48 90
90 is the greatest no.

Greatest of any three numbers using else if ladder:

User enter any three number and press enter button to show the greater number among the three number.

import java.util.*;
class Greatest
{
 public static void main(String args[])
 {
  int a,b,c;
  Scanner rd = new Scanner(System.in);
  System.out.println("Enter three numbers : ");
  a = rd.nextInt();
  b = rd.nextInt();
  c = rd.nextInt();
  if(a>b && a>c)
  {
   System.out.println( a+" is the greatest no.");
  }
  else if(b>a && b>c)
  {
   System.out.println(b+" is the greatest no.");
  }
  else
  { 
   System.out.println(c+" is the greatest no.");
  }
 }
}

Output:

Enter three numbers : 55 87 12
87 is the greatest no.

Greatest of any three numbers using ternary operator:

User enter any three number and press enter button to show the greater number among the three number.

import java.util.*;
class Greatest
{
 public static void main(String args[])
 {
  int a,b,c;
  Scanner rd = new Scanner(System.in);
  System.out.println("Enter three numbers : ");
  a = rd.nextInt();
  b = rd.nextInt();
  c = rd.nextInt();
  int max=(a>b)?(a>c)?a:c:(b>c)?b:c;
  System.out.println( max+" is the greatest no.");  
 }
}

Output:

Enter three numbers : 

60 45 33
60 is the greatest no.
