Union is a user-defined datatype. All the members of union share same memory location. Size of union is decided by the size of largest member of union. If you want to use same memory location for two or more members, union is the best for that.Unions are similar to structures. Union variables are created in same manner as structure variables. The keyword “union” is used to define unions in C language.Here is the syntax of unions in C language, union union_name { member definition; } union_variables;Here, union_name − Any name given to the union.member definition − Set of member ...

The operator ‘?’ is known as ternary operator as it requires three operands to act upon. It can be represented by “ ? : ”. It is also known as conditional operator. The operator improves the performance and reduces the lines of code.Here is the syntax of ternary operator in C language, Expression1 ? Expression2 : Expression3Here is an example of Ternary Operator in C language, Example Live Demo#include int main() { int a = -1; double b = 26.4231; int c = a? printf("True value : %lf", b):printf("False value : 0"); return 0; }OutputHere ...

Use the quotes property to set quotation marks. You can try to run the following code to implement the quotes propertyExampleLive Demo #demo { quotes: "'" "'"; } This is demo text surrounded by quotes.
An ArrayList can be converted into an Array using the java.util.ArrayList.toArray() method. This method takes a single parameter i.e. the array of the required type into which the ArrayList elements are stored and it returns an Array that contains all the elements of the ArrayList in the correct order.A program that demonstrates this is given as follows −Example Live Demoimport java.util.ArrayList; import java.util.List; public class Demo { public static void main(String[] args) { List aList = new ArrayList(); aList.add("James"); aList.add("Harry"); aList.add("Susan"); aList.add("Emma"); ...

ArrayBuffer object in JavaScript represents a fixed-length binary data buffer. The isView() function of this object accepts an argument and verifies whether it is view of ArrayBuffer (DataView, typed array). If so, it returns true else, it returns false.SyntaxIts syntax is as followsarrayBuffer.isView(arg)ExampleTry the following example. Live Demo JavaScript Example var arrayBuffer = new ArrayBuffer(5); arrayBuffer = ["apple", "orange", "mango"]; var bool = ArrayBuffer.isView(new Int32Array()) document.write(bool); OutputtrueExampleIn the same way if we try executing this function by passing an object ...

ArrayBuffer object in JavaScript represents a fixed-length binary data buffer.The slice() method of the this object returns a portion or, chunk from the array buffer (as a separate object). It accepts two integer arguments representing the start (inclusive) and end (exclusive) of the portion of the array to be returned.SyntaxIts syntax is as followsarrayBuffer.slice(start, end);ExampleTry the following example. Live Demo JavaScript Example var arrayBuffer = new ArrayBuffer(16); var int32View = new Int32Array(arrayBuffer); int32View[1] = 102; var sliced = new Int32Array(arrayBuffer.slice(4,12)); document.write(" "+sliced); Output102,0
A property called visibility allows you to hide an element from view. You can use this property along with JavaScript to create very complex menu and very complex webpage layouts.The visibility property can take the values listed in the table that followsValueDescriptionvisibleThe box and its contents are shown to the user.hiddenThe box and its content are made invisible, although they still affect the layout of the page.collapseThis is for use only with dynamic table columns and row effects.ExampleYou can try to run the following code to learn how to work with visible and hidden values ...

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 add() function of this object accepts a number and the position, adds the given number to the number in the given position and returns the value of the number in the old position.SyntaxIts syntax is as followsAtomics.add()Example Live Demo JavaScript Example var arrayBuffer = new SharedArrayBuffer(16); var data = new Uint8Array(arrayBuffer); data[0] = ...

All the elements of an ArrayList can be copied into an Object Array using the method java.util.ArrayList.toArray(). This method does not have any parameters and it returns an Object Array that contains all the elements of the ArrayList copied in the correct order.A program that demonstrates this is given as follows −Example Live Demoimport java.util.ArrayList; import java.util.List; public class Demo { public static void main(String[] args) { List aList = new ArrayList(); aList.add("Nathan"); aList.add("John"); aList.add("Susan"); aList.add("Betty"); aList.add("Peter"); Object[] objArr ...
