A JButton is a subclass of AbstractButton and it can be used for adding platform-independent buttons in a Java Swing application. A JButon can generate an ActionListener interface when the user clicking on a button, it can also generate the MouseListener and KeyListener interfaces. By default, we can create a JButton with a text and also can change the text of a JButton by input some text in the text field and click on the button, it will call the actionPerformed() method of ActionListener interface and set an updated text in a button by calling setText(textField.getText()) method of a JButton class.Exampleimport java.awt.*; import java.awt.event.*; import javax.swing.*; public ...

A JTextArea is a subclass of JTextComponent class and it is a multi-line text component to display the text or allow a user to enter the text. A JTextArea can generate a CaretListener interface when we are trying to implement the functionality of the JTextArea. By default, a JTextarea allows the orientation from left to right, if the user wants to enter a text from right to left by using the setComponentOrientation(ComponentOrientation.RIGHT_TO_LEFT) method of JTextArea class.Exampleimport java.awt.*; import javax.swing.event.*; import javax.swing.*; public class JTextAreaOrientationTest extends JFrame {    private JTextArea textArea;    public JTextAreaOrientationTest() {       setTitle("JTextAreaOrientation Test");       textArea = new ...

A JTableHeader is a subclass of JComponent class, When we create a JTable object, the constructor creates a new JTableHeader object to manage the table component's header. A JTable supplies a setTableHeader() method that establishes the table header component's JTableHeader object and a getTableHeader() method that returns a reference to the table header component's JTableHeader object. We can set a tooltip text to each column of a JTableHeader by overriding the getToolTipText() method of JTableHeader class.Exampleimport java.awt.*; import java.awt.event.*; import javax.swing.*; import javax.swing.table.*; public class JTableHeaderToolTipTest extends JPanel {    private DefaultTableModel dmodel;    private JTable table;    private JScrollPane jsp;    public JTableHeaderToolTipTest() ...

In this section, we will see how we can get the sum of all odd prime factors of a number in an efficient way. There is a number say n = 1092, we have to get all factor of this. The prime factors of 1092 are 2, 2, 3, 7, 13. The sum of all odd factors is 3+7+13 = 23. To solve this problem, we have to follow this rule −When the number is divisible by 2, ignore that factor, and divide the number by 2 repeatedly.Now the number must be odd. Now starting from 3 to square root ... Read More

In this section, we will see how we can get the largest prime factor of a number in an efficient way. There is a number say n = 1092, we have to get the largest prime factor of this. The prime factors of 1092 are 2, 2, 3, 7, 13. So the largest is 13. To solve this problem, we have to follow this rule −When the number is divisible by 2, then store 2 as largest, and divide the number by 2 repeatedly.Now the number must be odd. Now starting from 3 to square root of the number, if ... Read More

Here we will see the extended Euclidean algorithm implemented using C. The extended Euclidean algorithm is also used to get the GCD. This finds integer coefficients of x and y like below −𝑎𝑥+𝑏𝑦 = gcd(𝑎, 𝑏)Here in this algorithm it updates the value of gcd(a, b) using the recursive call like this − gcd(b mod a, a). Let us see the algorithm to get the ideaAlgorithmEuclideanExtended(a, b, x, y)begin    if a is 0, then       x := 0       y := 1       return b    end if    gcd := EuclideanExtended(b mod ...
