I got the answer bu doing some simple arithmetic. Create another class to select random number for bellow cases: step1: Taking current student index step2: Randomly selecting one student, whom number should reduce, rather than step1 student continuing again step1 and step2
You already have a String parameter, you can use it as it is, you do not need to create a new one, see: public Move(String r) { String move = r; } However, move will only be a local variable, you probably want something different, but that’s another step, which you will need to do … Read more
Variables of type int, bool, double, char, etc. are NOT objects. These types are called primitive types, so no constructor/destructor outside of memory allocation/deallocation. Look them up for more details.
the show() method gives you information about the refference itself( about a). Accesing a member of the object through “a” when “a” is not assigned to any object is illegal. show() will only display information regarding the “a” variable. Your show() method being static will run as thanks to your class. It is not bound … Read more
you got the whole list of objects in comments so give try following: foreach( $yourObj->stream->comments as $comment){ echo sprintf(‘%s: %s’, $comment->from->name, $comment->message); }
To meet your method name, you need this: protected bool IsStringAndNotNullAndEmpty(object value) { var s = value as string; return s == string.Empty; } Changing its name to IsEmptyString(object value) would be clearer though. It seems the OP actually wants a method that returns true for non-empty strings. So what is required is: protected bool … Read more
Here’s a plunker(just JS) :http://plnkr.co/edit/h3EndN8F6milHF2h1gAj?p=preview var array = [ { 9 : “Alfreds Futterkiste”, 10 : “Berlin”, Room : “201” }, { 9 : “Vaffeljernet”, 10: “Århus”, Room : “204” } ]; var result = {}; array.forEach(function(obj) { //function runs once for each element in the array, obj = element at current index result[obj.Room] = … Read more
Just filter the values and map the desired ones. array.filter allows you to filter items of an array with a condition, so using i => i.name === ‘test0′ will return a new array where only the values with name ‘test0’ are acquired. Finally, using map you create a new array, whose values are the result … Read more
You aren’t assigning a function and an object to the same variable you are redefining the what the symbol foo is bound to. Everytime you set foo = you are binding what is on the right hand side to that symbol. You can’t use this to access the function because it is a different object. … Read more
Objects in python have reference count which basically means the amount of places an object exist in. Using del removes one reference to the object (it does not force delete it). __del__ is then called when 0 references are left. You may create a new reference to the object and this way prevent it’s deletion … Read more
