What is a Java enum

Java Enums

A  Java  enum is a special  Java "class" that represents a group of constants (unchangeable variables, like final variables).

A Java enum is for instance : 

3 constant values e.g. Blue, Pink, Red 

or e.g. the 12 months of the year 

or the 7 days of the week etc. 

Java  enums save you typing the values.

One can get the value from the Java  enum. 

Java  enums avoid spelling errors and provide consistancy.

To create: 

enum Level {
  BAD,
  WORSE,
  TERRIBLE
}

To use: 

Level myLevel = Level.BAD;

The Seven Different Types of Coding Blocks in Java

-
Java   Coding Blocks    In Java , the term "coding block" typically refers to a block of code within certain constructs that define the scope and execution context of variables and statements. There are several types of coding blocks in Java, each serving different purposes. Here’s an overview: 1. Method Block A  Java  method block is the section of code within a method. It defines the scope of local variables and contains the statements that make up the method. public class MyClass { public void myMethod () { // Method block starts here int localVariable = 10 ; System.out.println(localVariable); // Method block ends here } } 2. Class Block A  Java  class block is the section of code within a class definition. It contains the class’s fields (variables), methods, and nested classes. public class MyClass { // Class block starts here int instanceVariable; // Field public void myMet...
