A new CharBuffer with the content as a shared subsequence of the original CharBuffer can be created using the method slice() in the class java.nio.CharBuffer. This method returns the new CharBuffer that is read-only if the original buffer is read-only and direct if the original buffer is direct.A program that demonstrates this is given as follows −Example Live Demoimport java.nio.*; import java.util.*; public class Demo { public static void main(String[] args) { int n = 5; try { CharBuffer buffer1 = CharBuffer.allocate(n); buffer1.put('A'); ...

To perform Regex search on integer value, you need to use $where operator. The syntax is as follows:db.yourCollectionName.find({ $where: "/^yourIntegerPatternValue.*/.test(this.yourFieldName)" });To understand the above concept, let us create a collection with document. The query to create a collection with document is as follows:> db.regExpOnIntegerDemo.insertOne({"StudentId":2341234}); { "acknowledged" : true, "insertedId" : ObjectId("5c70370c75eb1743ddddce21") } > db.regExpOnIntegerDemo.insertOne({"StudentId":123234}); { "acknowledged" : true, "insertedId" : ObjectId("5c70371175eb1743ddddce22") } > db.regExpOnIntegerDemo.insertOne({"StudentId":9871234}); { "acknowledged" : true, "insertedId" : ObjectId("5c70371875eb1743ddddce23") } > db.regExpOnIntegerDemo.insertOne({"StudentId":2345612}); { "acknowledged" : true, "insertedId" : ObjectId("5c70372275eb1743ddddce24") } > db.regExpOnIntegerDemo.insertOne({"StudentId":1239812345}); { "acknowledged" : true, "insertedId" : ...

To search a value in Java Decade Tuple, use the contains() method. It returns a booleans value i.e. TRUE if the element exist, else FALSE.Let us first see what we need to work with JavaTuples. To work with Decade class in JavaTuples, you need to import the following packageimport org.javatuples.Decade;Note Download JavaTuples Jar library to run JavaTuples program. If you are using Eclipse IDE, then Right Click Project -> Properties -> Java Build Path -> Add External Jars and upload the downloaded JavaTuples jar file. Refer the below guide for all the steps to run JavaTuplesSteps: How to run JavaTuples ... Read More

A vector shuffle can be done in the Fisher-Yates shuffle algorithm.In this algorithm, a linear scan of a vector is done and then swap each element with a random element among all the remaining element, including the element itself.AlgorithmBegin Declare a function show(). Pass a constructor of a vector as a parameter within show() function. for (auto const& i: input) Print the value of variable i. Declare v of vector type. Initialize some values into v vector in array pattern. ... Read More
To find inside a hash MongoDB, you can use dot(.) notation. Let us first create a collection with documents> db.hashDemo.insertOne({"ClientName":"Larry", "ClientAge":23, "ClientDetails":{ "isEducated": true, "ClientProject" : "University Management"}}); { "acknowledged" : true, "insertedId" : ObjectId("5ca1ef1266324ffac2a7dc5e") } > db.hashDemo.insertOne({"ClientName":"Chris", "ClientAge":26, "ClientDetails":{ "isEducated":false, "ClientProject" : "Online Book Store"}}); { "acknowledged" : true, "insertedId" : ObjectId("5ca1ef7766324ffac2a7dc5f") }Following is the query to display all documents from a collection with the help of find() method> db.hashDemo.find().pretty();This will produce the following output{ "_id" : ObjectId("5ca1ef1266324ffac2a7dc5e"), "ClientName" : "Larry", "ClientAge" : 23, "ClientDetails" : { "isEducated" ...

Ozone is measured as Dobson units. And a Dobson unit of gas is equal to a layer of gas, with a thickness of one-hundredth of a millimeter at the surface of the Earth. The ozone in the atmosphere is measured by about 300 Dobsons.Ozone is also known as a trace gas, meaning there are very few amounts in the atmosphere. In fact, it is concluded that out of every million molecules of gas in the atmosphere, less than ten are ozone. Though it does not sound or seems like much, it's enough to protect you from the Sun's UV rays.The ... Read More
In this program we will see how to subtract two 16-bit BCD numbers.Problem StatementWrite 8086 Assembly language program to subtract two 16-bit BCD numbers stored in memory offset 500H – 501H and 502H – 503H.DiscussionHere we are adding the 16-bit data byte by byte. At first we are subtracting lower byte and perform the DAS instruction, then Subtract higher bytes with borrow, and again DAS to adjust. The final result is stored at location offset 600H, and if borrow is present, it will be stored at 601H.We are taking two numbers 8523 - 7496 = 1027InputAddressData……50023501855029650374…… Flow Diagram Program OutputAddressData……600276011060200……
