How to use Scanner class for input in Java

Loops in Java Loops in Java are used to execute a block of code repeatedly as long as a certain condition is true. They help reduce code repetition and make programs more efficient. Types of Loops in Java 1. for loop Used when the number of iterations is known. for (int i = 1; i <= 5; i++) { System.out.println(i); } Output: 1 2 3 4 5 2. while loop Used when the number of iterations is not fixed; condition is checked before execution. int i = 1; while (i <= 5) { System.out.println(i); i++; } 3. do-while loop Similar to while, but the loop body executes at least once even if condition is false. int i = 1; do { System.out.println(i); i++; } while (i <= 5);

Understanding Cursors in Java In Java, a Cursor acts as an iterator that allows us to traverse or iterate through the elements of a Collection or Stream one by one. It provides a standardized way to access data sequentially without exposing the underlying structure of the collection. There are three main types of cursors in Java, each serving a specific purpose: *Iterator – Used to traverse elements in any Collection (like List, Set, etc.). It supports element removal during iteration. *ListIterator – A bidirectional iterator used specifically for Lists (like ArrayList, LinkedList). It allows both forward and backward traversal. *Enumeration – An older cursor, mainly used with legacy classes like Vector and Hashtable.

🚀 Java Date Formatting: Controlling Output with SimpleDateFormat ✍️ After covering the basic Date class, today I focused on formatting dates. The raw output of a Date object isn't always user-friendly, so the java.text.SimpleDateFormat class is essential for presenting dates in customized, readable ways. Key Formatting Patterns The SimpleDateFormat class uses specific pattern letters to define the output structure: Numeric Dates & Time: "dd/MM/yyyy HH:mm" (e.g., 14/11/2025 11:21): Uses numeric values for all components. Year-First Order: "yyyy/MM/dd" (e.g., 2025/11/14): Useful for file naming or strict international standards. Abbreviated Month/Day: "dd MMM yyyy" (e.g., 14 Nov 2025): Uses the short text representation for the month. Full Text Month: "dd MMMM yyyy" (e.g., 14 November 2025): Uses the full text name for the month. Day of the Week: "EEEE dd MMMM yyyy" (e.g., Friday 14 November 2025): Includes the full name of the day of the week. 🛠️ The Process The process is straightforward: Create a Date object (the data). Create a SimpleDateFormat object with the desired pattern (the presentation rule). Call the .format(Date obj) method to apply the rule and generate the formatted String. This control over presentation is vital for building clean user interfaces and standardizing data exchange!
