In this article, we will learn about the differences between a JScrollBar and a JScrollPane in Java. A JScrollBar is a component, and it doesn't handle its own events whereas a JScrollPane is a Container and it handles its own events and performs its own scrolling. A JScrollBar cannot have a JScrollPane whereas a JScrollPane can have a JScrollBar. JScrollBar The object of the JScrollBar class is used to add horizontal and vertical scrollbar which allow the user to select items between a specified minimum and maximum values. A JScrollBar class is an implementation of a scrollbar and inherits the ... Read More
In this article, we will learn about the importance of the CardLayout class in Java. In Swing, we usually have to manage a set of views and panels in a single container. The CardLayout class provides you with a flexible and powerful method to complete this, allowing you to switch between various components, such as cards in a deck. What is CardLayout? CardLayout is a layout manager in the Java AWT package. It is different from the other layouts, where the other layout managers attempt to display all the components within the container at once, the CardLayout displays only one ... Read More
In this article, we will learn to disable the maximize button of a JFrame in Java. When creating Swing GUIs in Java, we might occasionally want to prevent users from maximizing certain windows. Removing the maximize button will do the trick for dialog windows, tool windows, or any window where a fixed size needs to be kept. What is a JFrame? A JFrame is a class from javax. swing package and it can extend java.awt.frame class. It is a top-level window with a border and a title bar. A JFrame class has many methods that can be used to customize ... Read More
In this article, we will learn about the implementation of a JToggleButton in Java. The JToggleButton is a basic Swing component in Java that is used to represent a two-state button, i.e., selected or unselected. It is therefore the best component to use when adding on/off or mode selection functionality to Java applications. JToggleButton A JToggleButton is an extension of AbstractButton, and it can be used to represent buttons that can be toggled ON and OFF. When JToggleButton is pressed for the first time, it remains pressed and it can be released only when it is pressed for the second ... Read More
The layout managers are used to automatically decide the position and size of the added components. In the absence of a layout manager, the position and size of the components have to be set manually. The setBounds() method in Java is used in such a situation to set the position and size. To specify the position and size of the components manually, the layout manager of the frame can be null. The setBounds() Method The setBounds() is a method inherited from Java's AWT (Abstract Window Toolkit) and Swing libraries that enables manual positioning and sizing of GUI components. The setBounds() ... Read More
In this article, we have an unsorted array. Our task is to find the kth maximum element of that array using C++. Here is an example to understand the meaning of k. If k =2, you can say the second highest value, for k =3, the third highest value. The approaches that we will be using are mentioned below: Using Sorting Using Max Heap Using Min Heap Using Quick Select Using Binary Search Tree Using ... Read More
What is Python Tuple? A tuple in Python is an ordered collection of items that cannot be changed once, making it immutable. This allows duplicate values and can hold elements of different data types, such as strings, numbers, other tuples, and more. This makes tuples useful for grouping related data while determining the content remains fixed and unchanged. Example This code demonstrates different types of tuples in Python.my_tuple defines simple integer values. mixed_tuple contains different data types, including an integer, string, float, and Boolean. nested_tuple includes a tuple inside another tuple, along with a list. my_tuple = (1, 2, 3) ...

In this article, we will be learning about ClassCastException in Java. But before we jump into this, we'll understand what an exception is in Java. After that, we'll learn why and when ClassCastException occurs, look at real-world code examples that throw this exception, and finally learn how to avoid or resolve it. What is an Exception in Java? An exception in Java is an event that disrupts the normal flow of the program. Java provides a way to handle these errors gracefully using try-catch blocks. There are 2 types of exceptions: Checked Exceptions – ... Read More
In this article, we will learn to implement different borders using the BorderFactory in Java. While building graphical user interfaces (GUIs) with Java Swing, borders can be useful in structuring and managing various sections of our interface. To make it easier to develop several types of borders, Swing offers the BorderFactory class. What is a BorderFactory? The BorderFactory is a Factory class that provides different types of borders in Java BorderFactory, located in the javax.swing package, is a utility class containing static methods to create new Border objects. Because these methods internally manage border instances, you typically get reused border instances whenever ... Read More
In this article, we will learn to display the different font items inside a JComboBox in Java. The Swing framework provides a powerful JComboBox component that allows users to select an object from a drop-down list. What is a JComboBox? A JComboBox is a subclass of the JComponent class, and it is a combination of a text field and a drop-down list from which the user can choose a value. A JComboBox can generate an ActionListener, ChangeListener, and ItemListener interfaces when the user interacts with a combo box. Syntax The following is the syntax: JComboBox Box_Name = new JComboBox(array); Problem ... Read More
