A JTable is a subclass of JComponent class for displaying complex data structures. A JTable component can follow the Model View Controller (MVC) design pattern for displaying the data in rows and columns. A JTable can generate TableModelListener, TableColumnModelListener, ListSelectionListener, CellEditorListener, RowSorterListener interfaces. We can change the background and foreground color for each column of a JTable by customizing the DefaultTableCellRenderer class and it has only one method getTableCellRendererComponent() to implement it.Exampleimport java.awt.*; import javax.swing.*; import javax.swing.table.*; public class JTableColumnColorTest extends JFrame { private JTable table; private TableColumn tColumn; public JTableColumnColorTest() { setTitle("JTableColumnColor Test"); table = ...

Big projects are difficult to manage on mere text editors. You're likely to be more productive and less frustrated if you use an IDE in such cases. There are various types of IDE's and you should select the right one which fits your needs. There is no single best IDE for C++ on Windows. You must choose your tool wisely. Here is a list of popular and IMO best IDEs for Windows.Visual Studio − It is an IDE developed by Microsoft. This IDE has the best in class tooling for building, developing and profiling programs of C++ on Windows. Visual ... Read More

The static storage class instructs the compiler to keep a local variable in existence during the lifetime of the program instead of creating and destroying it each time it comes into and goes out of scope. Therefore, making local variables static allows them to maintain their values between function calls.The static modifier may also be applied to global variables. When this is done, it causes that variable's scope to be restricted to the file in which it is declared.In C++, when static is used on a class data member, it causes only one copy of that member to be shared ...

volatile means two things −- The value of the variable may change without any code of yours changing it. Therefore whenever the compiler reads the value of the variable, it may not assume that it is the same as the last time it was read, or that it is the same as the last value stored, but it must be read again.- The act of storing a value to a volatile variable is a "side effect" which can be observed from the outside, so the compiler is not allowed to remove the act of storing a value; for example, if ...

We use the const qualifier to declare a variable as constant. That means that we cannot change the value once the variable has been initialized. Using const has a very big benefit. For example, if you have a constant value of the value of PI, you wouldn't like any part of the program to modify that value. So you should declare that as a const.Objects declared with const-qualified types may be placed in read-only memory by the compiler, and if the address of a const object is never taken in a program, it may not be stored at all. For ... Read More
There are several alternatives for compiling C++ on Linux. Let's look at 2 of them −GCCAlmost all Linux distros come with GCC installed. Check whether GCC is installed on your system by entering the following command from the command line −$ g++ -vIf you have installed GCC, then it should print a message such as the following −Using built-in specs. Target: i386-redhat-linux Configured with: ../configure --prefix=/usr ....... Thread model: posix gcc version 4.1.2 20080704 (Red Hat 4.1.2-46)If GCC is not installed, then you will have to install it yourself using the detailed instructions available at https://gcc.gnu.org/install/. clangClang is a compiler developed ...

Step 0 − Install MinGW GCC or Cygwin GCCTo use Eclipse for C/C++ programming, you need a C/C++ compiler. On Windows, you could install either MinGW GCC or Cygwin GCC. Choose MinGW if you are not sure, because MinGW is lighter and easier to install, but has fewer features.MinGW GCC − To install MinGW, go to the MinGW homepage, www.mingw.org, and follow the link to the MinGW download page. Download the latest version of the MinGW installation program which should be named MinGW-.exe.While installing MinGW, at a minimum, you must install gcc-core, gcc-g++, Binutils, and the MinGW runtime, but you ...
