Java Program to display Larger number out of two

import java.io.*;
import java.util.*;
public class LargeSmall{
    Scanner scan=new Scanner(System.in);
    float a, b;
    public void input()throws IOException{
        System.out.println("Enter any two numbers: ");
        a=scan.nextFloat();
        b=scan.nextFloat();
    }

    public void display(){
        System.out.println("Large number out of "+a+", "+b+" is: "+(Math.max(a,b)));
        System.out.println("Small number out of "+a+", "+b+" is: "+(Math.min(a,b)));
    }

    public static void main(String[] args)throws IOException{
        LargeSmall obj=new LargeSmall();
        obj.input();
        obj.display();
    }
}

In above program "Math.max(a, b)" is use to check which number, a or b, is greater number and "Math.min(a, b)" is use to check which number, a or b, is smaller number.
