Claude 3.7 Sonnet and ChatGPT 4.0 are popular AI tools that are used for content generation, image generation, and more. Claude 3.7 Sonnet is used mainly very strong at coding, math, logical reasoning, while ChatGPT 4.0 is often better at natural language understanding and creative writing. In this article, we will discuss the important differences between Claude 3.7 Sonnet and ChatGPT 4.0. But before discussing the differences, let us first discuss their basics. What is a Claude 3.7 Sonnet? Cloud 3.7 is a new AI model tool launched by Anthropic in February 2025. This is one of its most innovative ... Read More
A collection is an object that holds a reference to other objects. A Java array list is one of the collections. it is a resizable array and is represented by the class named ArrayList. This java.util.Collections class provides methods to manipulate the collection objects in Java. We can make an ArrayList read-only using the Collections.unmodifiableList() method. Need to make a ArrayList Read-Only Sometimes we may need to make the ArrayList object read-only - To protect data from unnecessary or unwanted changes. ... Read More
The insertion sort technique is an in-place comparison-based sorting algorithm used to sort the numbers in an ascending or descending order. It is similar to the card sorting technique. In this technique, we pick up one element from the data set and shift the data elements to make a place to insert the picked-up element into the data set. In this article, we have an array of integers. Our task is to implement insertion sort in C++ to sort the given array. Example Here is an example of an array before sorting and after sorting using insertion sort: ... Read More
In this article, we will learn about the importance of OverlayLayout in Java. In Swing, layout managers offer various means of arranging components within a container like JPanel and JFrame. OverlayLayout provides the creation of layered or overlapping GUIs in Java. What is an OverlayLayout? An OverlayLayout is a subclass of Object class and it can arrange the components over the top of each other and uses components specified alignments to position them relatively. When different sizes are given to any of the components, we can see all the components. Syntax The following is the syntax: LayoutManager overlay = new ... Read More
In this article, we will learn about the differences between the paint() method and the repaint() method in Java. In the AWT and Swing frameworks, rendering graphical components is done in two different roles by the two methods paint() and repaint(). The paint() Method This method holds instructions to paint this component. In Java Swing, we can change the paintComponent() method instead of paint() method as paint calls paintBorder(), paintComponent() and paintChildren() methods. We cannot call this method directly instead we can call repaint(). Syntax The following is the syntax: public void paint(Graphics g) { // paint() method ... Read More
In this article, we will learn to minimize/maximize a JFrame programmatically in Java. In Swing, programmers often need to resize the window as needed. For example, they can shrink the window when carrying out background tasks or expand the window size for a better full-screen experience. What is a JFrame? A JFrame class is a subclass of Frame class and the components added to a frame are referred to as its contents, these are managed by the contentPane. A JFrame contains a window with title, border, (optional) menu bar and user-specific components. By default, we can minimize a JFrame by ... Read More
String buffer and StringBuilder both are mutable classes which can be used to do operation on string objects such as reverse of string, concating string and etc. We can modify a string without creating a new object of the string. A string buffer is thread-safe whereas string builder is not thread-safe. Therefore, it is faster than a string buffer. Also, a string concat + operator internally uses StringBuffer or StringBuilder class. Below are the differences. What is StringBuilder? The StringBuilder class in java is used to create and change a sequence of characters. In a regural string once the characters ... Read More
JVM has divided memory space between two parts: one is Stack and another one is Heap space. Stack space is mainly used for storing order of method execution and local variables. Stacks always store blocks in LIFO order whereas heap memory uses dynamic allocation for allocating and deallocating memory blocks. Memory allocated to the heap lives until one of the following events occurs : Program terminated Memory free What is a Heap memory? Heap memory is allocated for storing objects, arrays, and JRE (Java Runtime Environment) classes. Memory may be ... Read More
There are two ways to get a lock on the shared resource by multiple threads. One is a Reentrant Lock (or read/write lock), and the other is by using the Synchronized method. The reentrant lock class has been provided in the Java concurrency package from Java 5. It is the implementation of the Lock interface, and according to Java docs, the implementation of the Lock interface provides more extensive operation than can be obtained using synchronized method. What is the Reentrant lock? ReetrantLock is a class that implements the Lock Interface. It provides the synchronization feature with great flexibility, ... Read More
There are two ways to create a new thread of execution. One is to declare a class to be a subclass of the Thread class. This subclass should override the run method of the Thread class. An instance of the subclass can then be allocated and started. The other way to create a thread is to declare a class that implements the Runnable interface. That class then implements the run method. An instance of the class can then be allocated, passed as an argument when creating Thread, and started. Every thread has a name for identification purposes. More than one ... Read More
