Let's delve into Java code, "class" is the keyword used to describe the class. "Hello" is the user-defined class name. The "public" keyword is the access specifier used to describe that a class, method, or field is available for members outside that particular class. "static" keyword is used to declare members (variables, methods, blocks, or nested classes) that belong to a class itself, rather than to specific instances of that class. "void" specifies that the main method doesn't return any value. "main" is the specific name required for the JVM to recognize the entry point of the program, the method the JVM looks for to start execution. "String[] args" is an array of strings that holds the command-line arguments passed to the Java program when it is executed. It accepts an array of Strings as optional input from the command line after the name of the class.

#RestartJava Day - 1 There are three types of code used in the execution of Java programs:- 1. High-level code (Human Readable Code) 2. Intermediate Code (Partially Human Readable and partially Machine Readable) 3. Low-level Code (Machine Readable Code) The execution of the Java program is a two-step process i.e., Compilation and Interpretation. Compilation is the process of converting High-level code to Intermediate code. Interpretation is the process of converting Intermediate code to low-level code i.e., Machine-readable language. --> First, the user passes their instructions in the high-level language and saves the file(source file) in the destination folder of Java with ( .java ) extension. -->This ( .java) file will compiled by the java compiler i.e., javac. --> Java compiler(i.e., javac) checks for syntax mistakes, if the compiler finds any syntax mistake in the source file it will give COMPILE-TIME ERROR if there is no syntax mistake in the source file it will generate intermediate code i.e., byte code. --> This generated byte code will be checked by JVM i.e., Java Virtual Machine. --> JVM checks for logical mistakes, if JVM finds any logical mistake in byte code then it will generate RUN-TIME ERROR. If JVM does not find any logical mistake in the byte code then it will give the required output.

Day 14 ✅ Topic: Switch statements + Nested Case in Java Today, let's delve into the elegance of Java 12+ enhanced switch statements! ✨ Imagine a world where your code is not just functional, but also a joy to read and understand. With enhanced switches, Java gives us the power to transform mundane code into something truly beautiful. Let's take a classic example: switch(fruit){   case "mango":     System.out.println("King of fruits");     break;   case "apple":     System.out.println("Sweet fruit");     break;   case " orange":     System.out.println("Round fruit");     break;   case "banana":     System.out.println("Yellow fruit");     break;   default:     System.out.println("Unknown fruit"); } Now, behold the magic of enhanced switches: switch (fruit) {   case "mango" -> System.out.println("King of fruits");   case "apple" -> System.out.println("Sweet fruit");   case "orange" -> System.out.println("Round fruit");   case "banana" -> System.out.println("Yellow fruit");   default -> System.out.println("Unknown fruit"); } See the difference? The enhanced switch leverages a sleek arrow (`->`) syntax, creating code that's not just functional but also a pleasure to read. Clean, concise, and easy to grasp - that's the beauty of enhanced switches. The choice is yours - embrace the elegance of enhanced switches and elevate your code today! 🚀🌟 #Java #Programming #EnhancedSwitch #CodeElegance #LinkedInLearning 🖥️📘
