I just write this function for him. Please don’t justify people from how he write the code. Maybe it’s easy to say “Hey! Do you know javascript?”. It’s better if you leave some answer or stay quite.

The constructor initializes the variables(fields) of a class. The default constructor initializes to default values. Example, string to “”, integers to zero, doubles to 0.0, boolean to false an so on. When you create a constructor you’re customizing the variables initialization. 3 solved What Exactly Does A Constructor Do? (C++) [closed]
The line: $this->display = ” $this->n”.”$this->suf”.” $this->name”; is the first line of the class’ constructor. It stores in the $display property of the object a string that contains only spaces because the values it contains are not set yet. Read about double-quotes strings and variables parsing inside double-quotes strings. In order to work, the class … Read more
You could use reduce for this kind of thing, here is an example: var calendar = {Q1 : {P1 : {WK1 : {start: ‘1/1/2018’,end: ‘1/7/2018’},WK2 : {start: ‘1/8/2018’,end: ‘1/14/2018’}},P2 : {WK3 : {start: ‘1/15/2018’,end: ‘1/21/2018’}}},Q2 : {P3 : {WK5 : {start: ‘2/1/2018’,end: ‘2/7/2018’},WK6 : {start: ‘2/8/2018’,end: ‘2/14/2018’}},P4 : {WK7 : {start: ‘2/15/2018’,end: ‘2/21/2018’}}}}; var result … Read more
You need to give your “Person” a couple attributes either bool isBoy or string(Enum?) Gender as well as float bodyWeight or similar. Then you need to make a list of Person, and get the Average of each persons bodyWeight you can also search through this list to find where the person isBoy or gender matches … Read more
Note, you don’t need the size of the arraylist to iterate over it. You can simply do for (Entity e : myList){ //Do stuff with e } If you do need the index and hence need to call .size(), please post some sample code so someone can see what’s going wrong. 7 solved ArrayList.size() returns … Read more
Main m = new Main(); This code in class B will simply create an object of Main class. After this you need to call this to fill the arrayList. m.add() 1 solved Java Inheritance not working
You are trying to decode an array, either specify the specific item within the array, or make it a string. For instance: $unBillableArr=”{“id”:”123″, “to”:”+923412268656″, “MsgReceivedFrom”:”03349433314″, “message”:”Qwertyy”, “recdate”:”2017-11-20 19:01:49″}”; $json = json_decode($unBillableArr, true); // Or $unBillableArr = [‘{“id”:”123″, “to”:”+923412268656″, “MsgReceivedFrom”:”03349433314″, “message”:”Qwertyy”, “recdate”:”2017-11-20 19:01:49″}’]; $json = json_decode($unBillableArr[0], true); However, given the string you are receiving does not … Read more
Maybe I’m not understanding correctly what setDays() is meant to do, but it seems like this is what you would want: void numDays::setDays(int d) //mutator function to store the amount of days { days = d; hours = days * 8; } solved Why are my calculations are off? 1 work day is supposed to … Read more
You need to check existence of value in array using .indexOf(). If value doesn’t exist in array, insert it using .push(). About WinProbability, if exist, increase value of it. var json = [ {“ID”:1,”Nominee”:”12 Years a Slave”,”WinProbability”:0.00,”WinType”:”Win”}, {“ID”:2,”Nominee”:”12 Years a Slave”,”WinProbability”:2.81,”WinType”:”Win”}, {“ID”:3,”Nominee”:”12 Years a Slave”,”WinProbability”:0.66,”WinType”:”Nominated”}, {“ID”:1,”Nominee”:”American Hustle”,”WinProbability”:1.62,”WinType”:”Nominated”}, {“ID”:2,”Nominee”:”American Hustle”,”WinProbability”:0.85,”WinType”:”Win”}, {“ID”:3,”Nominee”:”American Hustle”,”WinProbability”:0.07,”WinType”:”Win”}, {“ID”:1,”Nominee”:”Captain Phillips”,”WinProbability”:2.70,”WinType”:”Nominated”}, {“ID”:2,”Nominee”:”Captain Phillips”,”WinProbability”:0.00,”WinType”:”Win”}, … Read more
this.name = other.name; I think that should work. Update: I forgot you want to swap their names, so: String aux = this.name; this.name = other.getName(); other.setName(aux); You will need a setName and getName methods since “name” is private. 5 solved How do you change the contents of an object in JAVA? [closed]
The issue here is that you’re not saving a reference to the original object… you’re overwriting your object variable in the for-loop and then returning the final value of that variable. Perhaps you should add a line like: var current = object; and then use current instead of object in the rest of your function. … Read more
Introduction Objects in Java are used to store data and can be manipulated in various ways. One of the most common ways to manipulate an object is to change its contents. This can be done by using the setter methods of the object. In this article, we will discuss how to change the contents of … Read more
