There are many ways to iterate/loop through an array. One common way it using a for loop. There can be many variations of a for loop: standard for loop (loops through numbers where i is each number): for(let i = 0; i < dangle.length; i++) { // loop through the dangle array let arr = … Read more
Try with Array#reduce . Updated with all key pair match Validate the edited array id value is available in original array using Array#map and indexOf function If not push entire object to new array First recreate the original array to object format like {key:[value]} Then match each key value pair match or not with forEach … Read more
You have a lot of error in your code : First Don’t ever name your variables with Upper letter in beginning, java use camelCase Second Don’t declare your variable with private public in your method. private ArrayList<Object> List = new ArrayList<Object>(); Third You can’t declare a method inside another method you have to close the … Read more
In C++, to make a custom object, you use classes, structs, and unions (although unions are a more advance topic). A class is a user-defined type, where the default access modifier is private. A struct is a class, but where the default access modifier is public. A union is a more advanced topic, you may … Read more
You can use reduce to create the result and operator in to check if the key exists: const obj = {“John”:44,”Sarah”:23,”Bob”:43,”Kate”:65,”Bill”:18}; const keys = [‘John’, ‘Bob’, ‘Kate’, ‘Bill’, ‘Fred’]; const result = keys.reduce((acc, el) => { if (el in obj) acc[el] = obj[el]; return acc; }, {}); console.log(result); Another approach is to convert the object … Read more
If you have an object like this. Follow this example: // THIS IS A SAMPLE, JUST TO SIMULATE how to access values inside class Google_Service_Oauth2_Userinfoplus { public $email=”[email protected]”; public $familyName=”Janorkar”; public $gender = null; public $givenName=”Mona”; public $hd = null; public $id = ‘11018813453254107047543’; public $name=”Mona Janorkar”; public $verifiedEmail = 1; protected $data = array( … Read more
Putting your arraylist inside a method means it can only be accessed by the method it is in and is lost when the method is finished running. You have two options. Change the return type of your method as an arraylist and return and manipulate your arraylist Create the arraylist outside of a method global … 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
I have no idea why, but changing the access specifier here: protected: D3DDraw m_cDraw; DXInput m_cInput; To public solved the problem, it’s a hack but I’m okay with that 😀 Thanks anyway for attempting to help solved C++ object reference corruption [closed]
You can parse the input string and split it about the comma , example:- String s1=”Casey Carter, Cartwright, [email protected]”; String[] arr=s1.split(“,”); // you will get each individual input terms i.e first name , lastname, email in string array Then you can build a string using it:- String s2=arr[1]+”,”+arr[0]; Note that this will build string Cartwright, … Read more
Your code is going to loop 1001 times, thus creating 1001 independent String-objects. s is a local variable inside the loop, thus the garbage collector is going to free the memory occupied by these no longer referenced instances as soon as the system needs the memory. Thus, I would not expect any memory issues. As … Read more
If for some bizarre reason you don’t know at run-time if an object has dispose implemented, you can use this dispose-safe function: /// —- IsDisposable ——————————– /// /// <summary> /// returns true if an object is disposable, false if not /// you can optionally dispose of it immediately /// </summary> public static Boolean IsDisposable(Object Item, … Read more
In java, you can do this by using Reflection: Reflection is commonly used by programs which require the ability to examine or modify the runtime behavior of applications running in the Java virtual machine. For example: try { addObject(c.newInstance(),x,y); } catch (InstantiationException | IllegalAccessException e) { e.printStackTrace(); } For more about reflection, you can read … Read more
Use map with filter: let posts = [{ “id”: 101, “title”: “Some post title” }, { “id”: 102, “title”: “Some Another post title” }, { “id”: 103, “title”: “Some Best post title ever” } ] let reviews = [{ “postId”: 101, “user”: “Chris”, “comment”: “Great post!” }, { “postId”: 101, “user”: “Jason”, “comment”: “Worth reading.” … Read more
Use Array.filter var clubs = [ {id: 1, name : ‘chelsea’}, {id: 2, name : ‘city’}, {id: 3, name : ‘liverpool’} ]; clubs = clubs.filter(function(item){ return item.id !== 2; }); console.log(clubs); 12 solved How can I remove a index in the array on the javascript?
