Use the setVerticalAlignment() method to align JLabel text vertically to the top:JLabel label = label.setVerticalAlignment(JLabel.TOP);The following is an example to align JLabel text vertically to the top:Exampleimport java.awt.Color; import java.awt.Font; import javax.swing.*; import javax.swing.border.Border; public class SwingDemo { public static void main(String args[]) { JFrame frame = new JFrame("Demo"); JLabel label; label = new JLabel("This is demo label!"); label.setFont(new Font("Verdana", Font.PLAIN, 14)); label.setVerticalAlignment(JLabel.TOP); Border border = BorderFactory.createLineBorder(Color.ORANGE); label.setBorder(border); frame.add(label); frame.setSize(600,300); frame.setVisible(true); } }Output
While creating a Statement object you can choose the concurrency and the type of the ResultSet object using the following variant of the createStatement() method −Statement createStatement(int resultSetType, int resultSetConcurrency)ResultSet ConcurrencyThe concurrency of the ResultSet object determines whether its contents can be updated or not.The ResultSet interface provides two values to specify the concurrency namely −CONCUR_READ_ONLY: If you set this as a value of the concurrency while creating the ResultSet object you cannot update the contents of the ResultSet you can only read/retrieve them.CONCUR_UPDATABLE: If you set this as a value of the concurrency while creating the ResultSet object you can update ...

In C++, we can use the inline keyword for functions. In C++ 17 version, the inline variable concept has come.The inline variable is allowed to be defined in multiple translation units. It also follows the one definition rule. If this is defined more than one time, the compiler merges them all into a single object in final program.In C++ (before C++17 version), we cannot initialize the value of static variables directly in the class. We have to define them outside of the class.Example Code#include using namespace std; class MyClass { public: MyClass() { ... Read More
To create a left-right split pane, let us create two components and split them −JComponent one = new JLabel("Left Split"); one.setBorder(BorderFactory.createLineBorder(Color.MAGENTA)); JComponent two = new JLabel("Right Split"); two.setBorder(BorderFactory.createLineBorder(Color.ORANGE));Now, we will split them. The two components will be split one to the left of the other using HORIZONTAL_PANE constant −JSplitPane splitPane = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT, one, two);The following is an example to create a left-right split pane in Java −Examplepackage my; import java.awt.Color; import javax.swing.BorderFactory; import javax.swing.JComponent; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.JSplitPane; public class SwingDemo { public static void main(String[] a) { JFrame frame = new JFrame("SplitPane ...

You can use count(1). Let us first see the syntax −select count(1) from yourTableName;Let us first create a table −mysql> create table DemoTable ( StudentName varchar(100) ); Query OK, 0 rows affected (0.84 sec)Insert some records in the table using insert command −mysql> insert into DemoTable(StudentName) values('John Smith'); Query OK, 1 row affected (0.24 sec) mysql> insert into DemoTable(StudentName) values('Chris Brown'); Query OK, 1 row affected (0.14 sec) mysql> insert into DemoTable(StudentName) values('David Miller'); Query OK, 1 row affected (0.16 sec) mysql> insert into DemoTable(StudentName) values('Carol Taylor'); Query OK, 1 row affected (0.15 sec)Display all records from ...

Steps to write my own header file in C −Type a code and save it as “sub.h”.Write a main program “subtraction.c” in which −include new header file.Write “sub.h” instead of All the functions in sub.h header are now ready for use.Directly call the function sub().Both “subtraction.c” and “sub.h” should be in same folder.Sub.hint sub(int m, int n) { return(m-n); }subtraction.cExample#include #include "sub.h" void main() { int a= 7, b= 6, res; res = sub(a, b); printf("Subtraction of two numbers is: %d", res); }After running ”subtraction.c” the output will be −OutputSubtraction of two numbers is: 1Read More
Broadcasting in computer network is a group communication, where a sender sends data to receivers simultaneously. This is an all − to − all communication model where each sending device transmits data to all other devices in the network domain.The ways of operation of broadcasting may be −A high level operation in a program, like broadcasting in Message Passing Interface.A low level networking operation, like broadcasting on Ethernet.Broadcasting is shown in the following figure −Advantages of BroadcastingBroadcast helps to attain economies of scale when a common data stream needs to be delivered to all, by minimizing the communication and processing ...

For this, you can use INSERT(). Let us first create a table −mysql> create table DemoTable -> ( -> ZipCode varchar(200) -> ); Query OK, 0 rows affected (0.47 sec)Insert some records in the table using insert command −mysql> insert into DemoTable values('9030'); Query OK, 1 row affected (0.15 sec) mysql> insert into DemoTable values('3902'); Query OK, 1 row affected (0.14 sec) mysql> insert into DemoTable values('9083'); Query OK, 1 row affected (0.20 sec) mysql> insert into DemoTable values('9089'); Query OK, 1 row affected (0.13 sec)Display all records from the table using select statement ...

There are n different activities are given with their starting time and ending time. Select maximum number of activities to solve by a single person.We will use the greedy approach to find the next activity whose finish time is minimum among rest activities, and the start time is more than or equal with the finish time of the last selected activity.The complexity of this problem is O(n log n) when the list is not sorted. When the sorted list is provided the complexity will be O(n).InputA list of different activities with starting and ending times.{(5, 9), (1, 2), (3, 4), ... Read More
ES6's template strings is a new way to combine strings. We already have methods such as join(), concat() etc to combine strings but the template strings method is the most sophisticated because it’s more readable, no backslash to escape quotes and no more messy plus operators.Using concat() and join()ExampleIn the following example join() and concat() methods are used to combine strings. If we observe carefully the code looks very messy.Live Demo const platform = 'Tutorix'; const joinMethod = ['The', 'best', 'e-learning', 'platform', 'is', platform].join(' '); document.write(joinMethod); ...
