Given three int values, a b c, return the largest. java code example

Example 1: Java program to find largest of three numbers

java program find largest of three numbers using command line argument
public class UsingCommandLineArgument
{
   public static void main(String[] args) 
   {
      int number1 = Integer.parseInt(args[0]);
      int number2 = Integer.parseInt(args[1]);
      int number3 = Integer.parseInt(args[2]);   
      if(number1 > number2 && number1 > number3)
      {
         System.out.println(number1 + " is largest number.");
      }
      else if(number2 > number1 && number2 > number3)
      {
         System.out.println(number2 + " is largest number.");
      }
      else   
      {
         System.out.println(number3 + " is largest number.");
      }
   }
}

Example 2: Java program to find largest of three numbers

Java program to find largest of four numbers using if-else
import java.util.Scanner;
public class FourNumbersUsingIfElse 
{
   public static void main(String[] args) 
   {
      Scanner sc = new Scanner(System.in);
      System.out.println("Please enter first number to find largest: ");
      int number1 = sc.nextInt();
      System.out.println("Please enter second number to find largest: ");
      int number2 = sc.nextInt();
      System.out.println("Please enter third number to find largest: ");
      int number3 = sc.nextInt();
      System.out.println("Please enter fourth number to find largest: ");
      int number4 = sc.nextInt();
      if(number1 > number2 && number1 > number3 && number1 > number4)
      {
         System.out.println(number1 + " is largest.");
      }
      else if(number2 > number1 && number2 > number3 && number2 > number4)
      {
         System.out.println(number2 + " is largest.");
      }
      else if(number3 > number1 && number3 > number2 && number3 > number4)
      {
         System.out.println(number3 + " is largest.");
      }
      else
      {
         System.out.println(number4 + " is largest.");
      }
      sc.close();
   }
