إلى من يريد شرح الجافا بليز بسرعه

[عاصي دوغان]

السلام عليكم انا وضعت من اول برنامج جافا وطلبت حله مع شرحه بليز اللي يعرف يحله ويشرحه والبرنامج هو
Write a program that prompts the user to input his full name and then generates a secure and unrepeatable new account user name that consists of three parts separated by an underscore for any system:

The first part contains the first letters of each part of the user full Name.
The second part contains the date of today with no spaces or symbols like "20112009".
The last part is generated through the following steps.
Generate a random integer number from 1 to 5
Generate a random float number from 0 to 1.0
Raise the float number to the power of the integer number and then print it in a form of two digits only after the decimal point.
Using math methods, bring the absolute of the resulted value and round it to the nearest number less than or equal to it.
Using wrapper methods, convert the integer part of the rounded number to a hexadecimal number. Integer.toHexString(n)
Finally, Concatenate all parts and print the whole Generated User Name.

وعليكم السلام ورحمة الله وبركاته .

الفقرة الأخيرة من السؤال غير واضحة ... ولكن تم برمجتها على ما فهمته :

import java.util.*;
import java..*;

 
class Account
{
    public String GetFirstLetter (String name)
    {
        String n1,n2,n3;
        n1 = name.substring(0, 1);
        name = name.substring(name.indexOf(" ") +1, name.length());
        n2 = name.substring(0, 1);
        name = name.substring(name.indexOf(" ") +1, name.length());
        n3 = name.substring(0, 1);
        return n1+n2+n3;
    }
 
    public String Today ()
    {
        Date d = new Date();
        SimpleDateFormat sdf = new SimpleDateFormat("ddMMyyyy");
        return sdf.format(d);
    }
 
    public String Number()
    {
        DecimalFormat df = new DecimalFormat("0.00");
        int x = 0 + (int) (Math.random() * (10 - 0));
        float y = 0 + (float) (Math.random() * (1 - 0));
        double p = Math.pow((double)y, (double)x);
        System.out.println("Random Number : " + p);
        float value = Float.parseFloat(df.format(p));
        value = Math.abs(value);
        value = Math.round(value);
        int t = (int) value;
        String hex = Integer.toHexString(t);
        return hex;
    }
}
public class Main {
 
    public static void main(String[] args) {
        Account ac1 = new Account();
        Scanner sc = new Scanner(System.in);
        System.out.print("Please enter your full name : ");
        String name = sc.nextLine();
        System.out.println("--------------");
        System.out.println("Name : " + ac1.GetFirstLetter(name));
        System.out.println("Today : " + ac1.Today());
        System.out.println("Final Number : " + ac1.Number());
    }
}
