You can use $lt operator for this. Let us create a collection with documents −> db.beforeSpecifyDateDemo.insertOne({"UserLoginDate":new ISODate('2016-03-21')}); { "acknowledged" : true, "insertedId" : ObjectId("5cbd91e4de8cc557214c0e0d") } > db.beforeSpecifyDateDemo.insertOne({"UserLoginDate":new ISODate('2016-05-11')}); { "acknowledged" : true, "insertedId" : ObjectId("5cbd91ecde8cc557214c0e0e") } > db.beforeSpecifyDateDemo.insertOne({"UserLoginDate":new ISODate('2017-01-31')}); { "acknowledged" : true, "insertedId" : ObjectId("5cbd91f9de8cc557214c0e0f") } > db.beforeSpecifyDateDemo.insertOne({"UserLoginDate":new ISODate('2018-05-15')}); { "acknowledged" : true, "insertedId" : ObjectId("5cbd9206de8cc557214c0e10") } > db.beforeSpecifyDateDemo.insertOne({"UserLoginDate":new ISODate('2019-04-01')}); { "acknowledged" : true, "insertedId" : ObjectId("5cbd9211de8cc557214c0e11") }Display all documents from a collection with the help of find() method. The query is as follows −> db.beforeSpecifyDateDemo.find().pretty();This will produce the ... Read More
You can use the concept of map reduce to get the position in an array. Let us first create a collection with documents −> db.retrievePositionDemo.find(); { "_id" : ObjectId("5cd569ec7924bb85b3f4893f"), "Subjects" : [ "MySQL", "MongoDB", "Java" ] }Following is the query to display all documents from a collection with the help of find() method −> db.retrievePositionDemo.find().pretty();This will produce the following output −{ "_id" : ObjectId("5cd569ec7924bb85b3f4893f"), "Subjects" : [ "MySQL", "MongoDB", "Java" ] }Following is the query to retrieve the position in an array in MongoDB ...

This is demo text. This is demo text. This is demo text. OutputIn the above example, we have set the two headings the − Demo Heading One Demo Heading Two
Whenever, you extend a class a copy of superclass’s members is available to the subclass object and, when you can call the method of the superclass using the object of the subclass.ExampleIn the following example, we have a class named SuperClass with a method with name demo(). We are extending this class with another class (SubClass).Now, you create an object of the subclass and call the method demo(). Live Democlass SuperClass{ public void demo() { System.out.println("demo method"); } } public class SubClass extends SuperClass { public ... Read More
