The JSON.parse() function accepts a JSON string, and constructs an object based on the given text and, returns it.SyntaxIts Syntax is as followsJson.parse();Example Live Demo JavaScript Example var jsonSample = '{"Tutorial": "Java", "Version":8 }'; jsonObj = JSON.parse(jsonSample); document.write("Tutorial Name: " + jsonObj.Tutorial); document.write(""); document.write("Tutorial Version: " + jsonObj.Version); OutputTutorial Name: Java Tutorial Version: 8
The stringify() function of a JSON object accepts a JSON string, and constructs an object based on the given text and, returns it.SyntaxIts Syntax is as followsJson.stringify();Example Live Demo JavaScript Example var jsonSample = '{Tutorial: Java, Version:8}'; jsonObj = JSON.stringify(jsonSample); document.write(jsonObj); Output"{Tutorial: Java, Version:8}"
A number is divisible by 11 if the difference between the sum of its alternative digits is divisible by 11.i.e. if (sum of odd digits) – ( sum of even digits) is 0 or divisible by 11 then the given number is divisible by 11.Programimport java.util.Scanner; public class DivisibleBy11 { public static void main(String args[]) { Scanner sc = new Scanner(System.in); System.out.println("Enter a number :"); String num = sc.nextLine(); int digitSumEve = 0; int digitSumOdd = 0; for(int i = 0; i
The current method name that contains the execution point that is represented by the current stack trace element is provided by the java.lang.StackTraceElement.getMethodName() method.A program that demonstrates this is given as follows −Example Live Demopublic class Demo { public static void main(String args[]) { System.out.println ("The method name is: " + new Exception().getStackTrace()[0].getMethodName()); } }OutputThe method name is: mainNow let us understand the above program.The method getMethodName() is used to obtain the current method name that contains the execution point that is represented by the current stack trace element. This is printed using ... Read More
The set() function of Map object adds or updates elements (key-value pairs) to a Map object.SyntaxIts Syntax is as followsmapVar.set()Example Live Demo JavaScript Example var mapVar = new Map(); mapVar.set('1', 'Java'); mapVar.set('2', 'JavaFX'); mapVar.set('3', 'HBase'); mapVar.set('4', 'Neo4j'); document.write(mapVar.has('3')); Outputtrue
If the sum of the digits of a number is divisible by 9, then the number is divisible by 9.Some examples of numbers divisible by 9 are as follows. The number 51984 is divisible by 9 because the sum of its digits (5+ 1 + 9 + 8 + 4 = 27) is divisible by 9.The number 91403 is not divisible by 9 because the sum of its digits (9 + 1 + 4 + 0 + 3 = 17) is not divisible by 9.Programimport java.util.Scanner; public class DivisibleBy9 { public static void main(String args[]) { Scanner sc = new Scanner(System.in); System.out.println("Enter a number :"); String num = sc.nextLine(); int digitSum = 0; for(int i = 0; i

ProgramFollowing is the example to calculate the GCD of the numbers of an array.Live Demopublic class GCDOfArrayofNumbers{ public static int gcd(int a,int b){ int res = 0; while (b > 0){ int temp = b; b = a % b; a = temp; res = a; } return res; } public static void main(String arg[]){ int[] myArray = {3, 6, 8}; int result = gcd(myArray[0],myArray[1]); for(int i = 2; i < myArray.length; i++){ result = gcd(result, myArray[i]); } System.out.println("Gcd of n numbers is: "+result); } }OutputGCD of n numbers is: 1
One of the features in Google hangouts ensures that no record of your chat history is stored. To enable this, you simply have to go to −Hangouts> Open any conversation> Go to Setting> check for the option 'Conversation History'> Uncheck the box placed in front of this option>Checked: History is turned on.Unchecked: History is turned off.Now the answer to your another question on retrieving the messages is that 'You, as a user' cannot retrieve; however, your employer, in case you use a shared network, can not only see but retrieve even from 'off' mode. Although, I know that Gmail claims ... Read More
L.C.M. or Least Common Multiple of two values, is the smallest positive value which the multiple of both values.For example multiples of 3 and 4 are:3 → 3, 6, 9, 12, 15 ...4 → 4, 8, 12, 16, 20 ...The smallest multiple of both is 12, hence the LCM of 3 and 4 is 12.ProgramFollowing example computes the LCM of array of numbers.Live Demopublic class LCMofArrayOfNumbers { public static void main(String args[]) { int[] myArray = {25, 50, 125, 625}; int min, max, x, lcm = 0; for(int i = 0; i
