present a basic understanding of object-oriented programming (OOP), for example by explaining how somewhat larger programming assignments can be solved
In java, every object is either a primitive type or reference. All the classes, enums, arrays are reference types and inherit from java.lang.Object. Primitive types are – boolean, byte, short, int, long, char, float, and double. java.lang.Class is the entry point for all the reflection operations.
OOP helps to keep the Java code DRY "Don't Repeat Yourself", and makes the code easier to maintain, modify and debug. The returned Class object is the object that is locked by static synchronized methods of the represented class. The actual result type is Class where |X| is the erasure of the static type of the expression on which getClass is called. For example, no cast is … Using new operator. This is the most commonly used method of creating an object and almost all … Using new Keyword. Using the new keyword is the most popular way to create an object or instance … Basically, the ObjectOutputStream encodes Java objects using the class name and object values.

I am not a keen user of java but I know in many other programming languages a foreach loop would be the most simple way of doing this. After a bit of research I found the following link which suggests the code below.
Below is an example of what the str
The first line creates an object of the Point class, and the second and third lines each create an object of the Rectangle class. Each of these statements has three parts (discussed in detail below): Declaration: The code set in bold are all variable declarations that associate a variable name with an object type.; Instantiation: The new keyword is a Java operator that creates the object. For example: Your mobile, it’s an example of object which has a lots of characteristics like color, RAM, camera etc and behaviors like calling, messaging etc. How To Create Object: Suppose Mobile is the class for which we want to create object name abhi.

However, in our example we are only guaranteed that the currency won't change, so we must rely on the Currency API to protect itself from changes. Most of the time, we need the attributes of an object to hold custom values, and the place to initialize the internal state of an immutable object is its constructor:
