Java Largest Three Number Example

Program that will find Largest Number from given Three Numbers

Method 1

class LargestThreeNo{

public static void main(String args[]){

int a=10,b=20,c=30;
if(a>b){
if(a>c){
System.out.println("a is Largest");
}else
{
System.out.println("c is Largest");
}
}else{

if(b>c){

System.out.println("b is Largest");
}else{

System.out.println("c is Largest");
}
}

}

}

Output

c is Largest 

Method 2

class LargestThreeNo{

public static void main(String args[]){

int a=10,b=20,c=30;
int large;
large = (a>b)?((a>c)?a:c):((b>c)?b:c);
System.out.println("Largest No ==> " + large);
}

}

Output

Largest No ==> 30 

Method 3

import java.util.*;

class LargestThreeNo{

public static void main(String args[]){

int a=10,b=20,c=30;
int large;
Scanner in = new Scanner(System.in);
  System.out.print("Enter a b and c Number ==> ");
  a = in.nextInt();
  b = in.nextInt();
  c = in.nextInt();
large = (a>b)?((a>c)?a:c):((b>c)?b:c);
System.out.println("Largest No ==> " + large);
}

}

Output

Enter a b and c Number ==> 10 20 30

Largest No ==> 30 

Method 4

import java.util.*;

class LargestThreeNo{

public static void main(String args[]){

int a=10,b=20,c=30;
int large;
a = Integer.parseInt(args[0]);
     b = Integer.parseInt(args[1]);
     c = Integer.parseInt(args[2]);

large = (a>b)?((a>c)?a:c):((b>c)?b:c);
System.out.println("Largest No ==> " + large);
}

}

Output

Method 5

import java.util.*;

class LargestThreeNo{
int large;
LargestThreeNo()
{
  int a,b,c;
  Scanner in = new Scanner(System.in);
  System.out.print("Enter a b and c Number ==> ");
  a = in.nextInt();
  b = in.nextInt();
  c = in.nextInt();
  large = (a>b)?((a>c)?a:c):((b>c)?b:c);
}

void display()
{
System.out.println("Largest No ==> " + large);
}
}
class main{
public static void main(String args[]){
LargestThreeNo l =new LargestThreeNo();
l.display();
}

}

Output

Enter a b and c Number ==> 10 20 30

Largest No ==> 30
