To highlight multiple rows in a table, you can use the addRowSelectionInterval() method. At first create a table −DefaultTableModel tableModel = new DefaultTableModel(); JTable table = new JTable(tableModel);Add some columns −tableModel.addColumn("Language/ Technology"); tableModel.addColumn("Text Tutorial"); tableModel.addColumn("Video Tutorial"); tableModel.addColumn("Views");Now, add rows to the table −tableModel.addRow(new Object[] { "NodeJS", "No", "Yes", "2350"}); tableModel.addRow(new Object[] { "MVC", "Yes", "No", "1500"}); tableModel.addRow(new Object[] { "ASP.NET", "Yes", "Yes", "3400"}); tableModel.addRow(new Object[] { "F#", "Yes", "No", "7890"}); tableModel.addRow(new Object[] { "Blockchain", "Yes", "No", "10600"}); tableModel.addRow(new Object[] { "SharePoint", "Yes", "Yes", "4900"});Highlight multiple rows by adding interval of rows from both ends. Set interval (index) for both the ...
Read MoreWhat is the effect of extern "C" in C++?
The extern “C” keyword is used to make a function name in C++ have the C linkage. In this case the compiler does not mangle the function. Let us see what is the mangling in C++ first, then we can discuss about the extern “C” keyword.In C++ we can use the function overloading feature. Using this feature, we can create functions with same name. The only difference is the type of the arguments, and the number of arguments. The return type is not considered here. Now the question comes how the C++ distinguishes overloaded functions in object code?In the object ...
Read MoreJava program to get the previous sibling from a JTree
Use the getPreviousSibling() method to get the previous sibling. Here, we are getting the previous sibling of child node “five” and displaying on Console −System.out.println("Get Previous Sibling = "+five.getPreviousSibling());The following is an example to get the previous sibling from a JTree −Examplepackage my; import javax.swing.JFrame; import javax.swing.JTree; import javax.swing.tree.DefaultMutableTreeNode; public class SwingDemo { public static void main(String[] args) throws Exception { JFrame frame = new JFrame("Demo"); DefaultMutableTreeNode node = new DefaultMutableTreeNode("Products"); DefaultMutableTreeNode node1 = new DefaultMutableTreeNode("Clothing (Product1 - P66778)"); DefaultMutableTreeNode node2 = new DefaultMutableTreeNode("Accessories (Product2 - P66779)"); ...
Read MoreHow do I convert between big-endian and little-endian values in C++?
Here we will see how to convert Little endian value to Big endian or big endian value to little endian in C++. Before going to the actual discussion, we will see what is the big endian and the little endian?In different architectures, the multi-byte data can be stored in two different ways. Sometimes the higher order bytes are stored first, in that case these are known as big endian, and sometimes the lower order bytes are stored first, then it is called little endian.For example, if the number is 0x9876543210, then the big endian will be −The little endian will ...
Read MoreHow to include libraries in Visual Studio 2012?
To add libraries in Visual Studio 2012, there are two different methods. The first one is manual method. The second one is adding libraries from code.Let us see the manual method first.To add some library, we have to follow these five steps −Add the #include statements necessary files with proper declarations. For example −#include “library.h”Add the include directory for the compiler look up;Go to the Configuration Properties/VC++ Directories/Include DirectoriesThen click and edit, and add new entryAdd one library directory for *.lib files:Go to project (on top bar) -> properties -> Configuration Properties -> VC++ Directories -> Library Directories, then click ...

Read MoreHow do I catch a Ctrl+C event in C++?
The CTRL + C is used to send an interrupt to the current executing task. In this program, we will see how to catch the CTRL + C event using C++.The CTRL + C is one signal in C or C++. So we can catch by signal catching technique. For this signal, the code is SIGINT (Signal for Interrupt). Here the signal is caught by signal() function. Then one callback address is passed to call function after getting the signal.Please see the program to get the better idea.Example#include #include #include #include using namespace std; // Define ...
