عضو جديد داخل عليكم ورامي عقاله ..

اكتب هنا الاسئله كامله ، سواءاً انجليزي ولا فرنسي ( ايطالي كالشيو مانتقبل :lol: )

ولاترمي عقالك ياخوك تراك عزيز وغالي

بدعاء مستقبل الناجح و المشرق لك يا أخي MO ,

كما قال أخ عيسى أكتب الأسئلة كاملة و سوف نحول المساعدة (h)

مشكورين حبايب قلبي عالردود

أوكي

راح أنسخ لكم الأسئلة

السؤال الأول

Q1. Define a class called Counter whose objects count things. An object of this class records a count that is a nonnegative integer. Include methods to set the counter to 0, to increase the count by 1, and to decrease the count by 1. Be sure that no method allows the value of the counter to become negative. Include an accessor method that returns the current count value and a method that outputs the count to the screen. There should be no input method or other mutator methods. The only method that can set the counter is the one that sets it to zero. Also, include a toString method and an equals method. Write a program (or programs) to test all the methods in your class definition.

السؤال الثاني

Q2. Write a Temperature class that has two instance variables: a temperature value (a floating-point number) and a character for the scale, either C for Celsius or F for Fahrenheit. The class should have four constructor methods: one for each instance variable (assume zero degrees if no value is specified and Celsius if no scale is specified), one with two parameters for the two instance variables, and a no-argument constructor (set to zero degrees Celsius). Include the following: (1) two accessor methods to return the temperature—one to return the degrees Celsius, the other to return the degrees Fahrenheit— use the following formulas to write the two methods, and round to the nearest tenth of a degree:

degreesC = 5(degreesF - 32)/9

degreesF = (9(degreesC)/5) + 32

(2) three mutator methods: one to set the value, one to set the scale (F or C), and one to set both; (3) three comparison methods: an equals method to test whether two temperatures are equal, one method to test whether one temperature is greater than another, and one method to test whether one temperature is less than another (note that a Celsius temperature can be equal to a Fahrenheit temperature as indicated by the above formulas); and (4) a suitable toString method. Then write a driver program (or programs) that tests all the methods. Be sure to use each of the constructors, to include at least one true and one false case for each of the comparison methods, and to test at least the following temperature equalities: 0.0 degrees C = 32.0 degrees F, -40.0 degrees C = -40.0 degrees F, and 100.0 degrees C = 212.0 degrees F.

السؤال الثالث

Q3. Define a class whose objects are records on animal species. The class should have instance variables for the species name, population, and growth rate. The growth rate is a percentage that can be positive or negative and can exceed 100 percent. Include a suitable collection of constructors, mutator methods, and accessor methods. Include a toString method and an equals method. Include a boolean valued method named endangered that returns true when the growth rate is negative and returns false otherwise. Write a test program (or programs) that tests each method in your class definition.

ما أتوقع إنها صعبة عليكم

ولكن الرجاء مراعاة إن المستوى اللي وصلنا له هو ال Classes وال Loops وإدخال البيانات من المستخدم فقط .. تونا في البداية .. :)

أتمنى الرد بأسرع فرصة

السؤال الثاني والثالث أكتب محاولتك هنا ووضح مشكلتك وين وابشر

مشكووووووووووووووور يالغالي

طيب إذا ممكن أحد يراجع معاي الخطأ في البرنامج الثاني عندي .. اللي هو Tempreture حطيت الكود كامل بس فيه خطأ

ممكن تضيفه على شكل كود هنا ؟

عشان يكون الكود واضح فقط ، انسخ كودك وحطه هنا ثم اضغط على زر الكود ،

مشكور حبيب قلبي عيسى على تفاعلك ..

حليت المسائل كلهاااا لانه إنتهى وقت التسليم .. وسلمتها ..

إذا تبغون نسخ من البرامج .. تشوفونها وتقيمونها ..
