this is my first try in Java

Main.java

package com.ShannaX;

import java.text.NumberFormat;
import java.util.Arrays;
import java.util.Scanner;

public class Main {

    public static void main(String[] args) {
        try (Scanner scanner = new Scanner(String.valueOf(args))) {
            System.out.println(Arrays.toString(args));
        }

        //Math class
        int randNum = (int) (Math.random()*100);

        //format
        String result = NumberFormat.getPercentInstance().format(0.1);
        System.out.println(result);

        //reading input
        Scanner scanner = new Scanner(System.in);
        System.out.print("What's your name : ");
        String name = scanner.nextLine().trim();
        System.out.println("you are " + name);

    }
}
