Let us first create a TreeSet and add elements to it:TreeSet treeSet = new TreeSet(); treeSet.add(20); treeSet.add(50); treeSet.add(100); treeSet.add(120); treeSet.add(150); treeSet.add(200); treeSet.add(250); treeSet.add(300); treeSet.add(350); treeSet.add(400);Now, let us get Tail Set from the TreeSet. In the below case, we will get elements above 200:SortedSet set = treeSet.tailSet(200);Exampleimport java.util.SortedSet; import java.util.TreeSet; public ... Read More

This represents a scrollable ResultSet i.e. the cursor moves in forward or backward directions. This type of ResultSet is insensitive to the changes that are made in the database i.e. the modifications done in the database are not reflected in the ResultSet.Which means if we have established a connection with ...

At first set a LocalDateTime:LocalDate date = LocalDate.now(); LocalTime time = LocalTime.now(); LocalDateTime dateTime = LocalDateTime.of(date, time);Now, convert the LocalDateTime to LocalDate and LocalTime:LocalDate localDate = LocalDateTime.now().toLocalDate(); LocalTime localTime = LocalDateTime.now().toLocalTime();Exampleimport java.time.LocalDate; import java.time.LocalDateTime; import java.time.LocalTime; public class Demo {    public static void main(String[] args) {       ...

To format and display date like this i.e. YearMonth, you need to set the pattern:uuuuMMAt first, set a LocalDate:LocalDate localDate = LocalDate.now();Now format and display date as ‘201904’:localDate.format(DateTimeFormatter.ofPattern("uuuuMM"))Exampleimport java.time.LocalDate; import java.time.format.DateTimeFormatter; public class Demo {    public static void main(String[] args) {       LocalDate localDate = LocalDate.now();   ...

Network Control Protocol (NCP) is a set of protocols forming a part of Point − to − Point Protocol (PPP). PPP is a data link layer protocol that is used to transmit multiprotocol data between two directly connected (point-to-point) computers. PPP is composed of link control protocol (LCP), authentication protocol ... Read More

In the TYPE_SCROLL_INSENSITIVE ResultSet, the cursor moves in forward or backward directions.

Let’s say the following is our list which isn’t read-only:List < Integer > list = new ArrayList < Integer > (); list.add(10); list.add(20); list.add(30); list.add(40); list.add(50); list.add(20); list.add(40); list.add(50);Convert the above list to Read-only:list = Collections.unmodifiableList(list);On conversion, now you won’t be add or remove elements from the List. Let us ... Read More

In computer networking and telecommunications, when a transmission unit is sent from the source to the destination, it contains both a header and the actual data to be transmitted. This actual data is called the payload. The header contains the protocol information as well as the source and destination addresses, ... Read More
