The Atomic object of JavaScript is an object and which provides atomic operations such as add, sub, and, or, xor, load, store etc. as static methods, these methods are used with SharedArrayBuffer objects.The or() function of the atomic object accepts a value representing the position of an array, performs bitwise OR operation on the value in the given position and returns the old value in it.SyntaxIts syntax is as followsAtomics.or(data, 0, 30)Example Live Demo JavaScript Example var arrayBuffer = new SharedArrayBuffer(16); var data = new Uint8Array(arrayBuffer); ...

There are so many cases, we should create dynamic view rather than creating view in XML. In that scenario, we should need to get the dimensions of a view. So here is a simple solution to get the dimensions of a view in android.To get the height of any view use the following codeint width = view.getMeasuredHeight();To get the width of any view use the following codeint height = view.getMeasuredWidth();Before get the width and height, we should assign default measure for a view as shown belowview.measure(0, 0);In the above code view is like either textview ,editText, button ..etc. Here is ...

The Atomic object of JavaScript is an object and which provides atomic operations such as add, sub, and, or, xor, load, store etc. as static methods, these methods are used with SharedArrayBuffer objects.This method is used to determine whether to use locks or atomic operations.SyntaxIts syntax is as followsAtomics.isLockFree(size)Example Live Demo JavaScript Example document.write(Atomics.isLockFree(7)); document.write(""); document.write(" "+Atomics.isLockFree(8)); Outputfalse false
CSS provides a property called overflow that tells the browser what to do if the box's contents are larger than the box itself. The following are the values of overflow property −ValueDescriptionVisibleAllows the content to overflow the borders of its containing element.HiddenThe content of the nested element is simply cut off at the border of the containing element and no scrollbars are visible.ScrollThe size of the containing element does not change, but the scrollbars are added to allow the user to scroll to see the content.autoThe purpose is the same as a scroll, but the scrollbar will be shown only if the ...

Android AsyncTask going to do background operation on background thread and update on main thread. In android we cant directly touch background thread to main thread in android development. asynctask help us to make communication between background thread to main thread.Methods of AsyncTaskonPreExecute() − Before doing background operation we should show something on screen like progressbar or any animation to user. we can directly comminicate background operation using on doInBackground() but for the best practice, we should call all asyncTask methods .doInBackground(Params) − In this method we have to do background operation on background thread. Operations in this method should ... Read More
To remove all the elements from HashSet, use the clear() method.Create a HashSet and initialize elements −String strArr[] = { "P", "Q", "R", "S" }; Set s = new HashSet(Arrays.asList(strArr));Now, to remove all the above elements −s.clear()The following is an example to remove all elements from a HashSet −Example Live Demoimport java.util.Arrays; import java.util.HashSet; import java.util.Set; public class Demo { public static void main(String[] a) { String strArr[] = { "P", "Q", "R", "S" }; Set s = new HashSet(Arrays.asList(strArr)); strArr = new String[] { "R", "S", "T", "U" }; ...
