We are inserting a tab just after the first tab by using the index value 1. Here, index 1 would be location 2nd i.e. just after the first tab of the JTabbedPane container.The following is an example to insert a tab after the first tab −Examplepackage my; import javax.swing.*; import java.awt.*; public class SwingDemo { public static void main(String args[]) { JFrame frame = new JFrame("Devices"); JTabbedPane tabbedPane = new JTabbedPane(); JTextArea text = new JTextArea(100, 100); JPanel panel1, panel2, panel3, panel4, panel5, panel6, panel7, panel8; ...

Let’s say, we have selected a range of rows using addRowSelectionInterval() as shown in the demo screenshot −Now, we will deselect the above shown selected rows using removeRowSelectionInterval(). The range is to be set here for interval i.e rows 3 to 6 (index 2 to 5) will get deselected −table.removeRowSelectionInterval(2, 5);The following is our example to deselect a range of rows −Examplepackage my; import javax.swing.JFrame; import javax.swing.JScrollPane; import javax.swing.JTable; import javax.swing.table.DefaultTableModel; public class SwingDemo { public static void main(String[] argv) throws Exception { DefaultTableModel tableModel = new DefaultTableModel(); JTable table = new JTable(tableModel); ...

In C or C++, we cannot create random float directly. We can create random floats using some trick. We will create two random integer values, then divide them to get random float value.Sometimes it may generate an integer quotient, so to reduce the probability of that, we are multiplying the result with some floating point constant like 0.5.Example#include #include #include using namespace std; main() { srand((unsigned int)time(NULL)); float a = 5.0; for (int i=0;i

Yes, we can do that with Java Swings as shown below. Here, we have a panel set with GridLayout and another panel with BorderLayout −JPanel panelGrid = new JPanel(new GridLayout(10, 5, 10, 10)); panelGrid.add(new JCheckBox("Demo CheckBox1")); panelGrid.add(new JCheckBox("Demo CheckBox2")); panelGrid.add(btnAPanel); panelGrid.add(btnBPanel); panelGrid.add(btnCPanel); panelGrid.add(btnDPanel); JPanel panelBrdLayout = new JPanel(new BorderLayout()); panelBrdLayout.add(panelGrid, BorderLayout.NORTH);The following is an example to combine GridLayout and BorderLayout −package my; import java.awt.BorderLayout; import java.awt.Dimension; import java.awt.GridLayout; import javax.swing.JButton; import javax.swing.JCheckBox; import javax.swing.JFrame; import javax.swing.JPanel; public class SwingDemo { public static void main(String[] args) { JButton btnA = new JButton("Button1"); JButton btnB ...
