Input three number from user and compare these number with each others and find largest number among these three numbers. Here i am using ternary operator for find largest number. Read more about ternary operator Click here

import java.util.Scanner;

class greatestnumber
{
public static void main(String[] args) 
{
int a,b,c,largest;
Scanner s=new Scanner(System.in);
System.out.println("Enter any three numbers: ");
a=s.nextInt();
b=s.nextInt();
c=s.nextInt();

if(a>=b && a>=c) 
{
System.out.println("Largest number: "+a);
}
if(b>=a && b>=c) 
{
System.out.println("Largest number: "+b);
}
if(c>=a && c>=b) 
{
System.out.println("Largest number: "+c);
}
}
}

Enter any three numbers :
7 
24
3
Largest number: 24

import java.util.Scanner;
class greatestnumber
{
public static void main(String[] args) 
{
int a,b,c,largest;
Scanner s=new Scanner(System.in);
System.out.println("Enter any three numbers: ");
a=s.nextInt();
b=s.nextInt();
c=s.nextInt();
largest=(a>b)?(a>c?a:c):(b>c?b:c);
System.out.println("Largest number: "+largest);
}
}

Enter any three numbers :
7 
6
11
Largest number: 11

Syntax to compile and run java program

for compile -> c:/>javac greatestnumber.java
for run -> c:/>java greatestnumber

• Scanner s=new Scanner(System.in): are used for receive input from keyboard.
• nextInt(): method are used for get integer type value from keyboard.
• System.out.println("....."): are used for display message on screen or console.
