المشاركة الأصلية كتبت بواسطة أبـو فـيـصـل تكفون ابي اعرف طريقة حل هالسؤال : Write a program that inputs an integer, n, from the command line and displays the string “1 + 2 + 3 + 4 + ... + n = sum.” For example, if the command-line argument is 7, the output should be: 1 + 2 + 3 + 4 + 5 + 6 + 7 = 28 Make sure the number entered on the command line is positive. وهذا السؤال ايضا : public class RandomLoop { public static void main(String [] args) { int a, b; a = (int) (Math.random() * 10 + 1); System.out.println(“a = “ + a); do { b = (int) (Math.random() * 10 + 1); System.out.println(“Trying b = “ + b); }while(a == b); System.out.println(“a = “ + a + “ and b = “ + b); } } بتغيير randomloop الى do و while loop وشكرا لكم
