    هذا السؤال

    ----------
    . Take two positive integers from the user.
    a. You program will check that user has given the correct positive number (number > 0). If user
    has given 0 or a negative number then your program repeatedly ask the user to give the
    correct positive number until he gives the correct input.
    b. If the first number is smaller than the second number, given by user, then swap the numbers.
    2. Write a Method that will take an integer value as a parameter and convert the integer value into a
    Hexadecimal number as a String and return the string back to the calling method.
    a. public static String decimal2hexadecimal(int num) - header of the method
    3. Write a Method that takes two Hexadecimal Numbers as strings and computes their sum as a string
    and return the result to calling function.
    a. public static String addHexadecimal(String num1, String num2) - header of the method that
    computes num1 + num2 as a string.
    4. Write a Method that takes two Hexadecimal Numbers as strings and computes their difference as a
    string and return the result to calling function.
    a. public static String subtractHexadecimal(String num1, String num2) - header of the
    method that computes num1 – num2 as a string.

    شكرا،
    الآن انا عندي مشكلة مع For Loop
    أبغا أضرب عددين في بعضهم بإستخدام هاي الطريقة
    https://www.youtube.com/watch?v=XYOkNPTbZIk
    والحل فور لووب داخل فور لووب
    كيف اعملها؟
    انا ملخبط في كيفية استخدام الفور لووب

    بإختصار بدي العدد الأول يضرب جميع الأعداد من العدد الثاني
    ثم ينتقل للخانة الثانية من العدد الأول ويعيد الكرة
