In the process of making a software, it takes a special language to translate it into a machine, which will be processed according to our wishes. There are many programming languages ​​available. The goal itself is to be able to build a website or mobile application that is good and right and can set the engine to do something, according to the system that we make ourselves.

In the development process, there are three basic structures including algorithms, databases and data structures. These three structures really need to be understood by developers to be able to properly customize and complement a website or mobile application. Website consists of a collection of pages in a particular domain with a variety of existing information. The fundamental of the website programming language is HTML, a basic understanding of a developer that must be mastered first, before learning or using other programming languages. In addition to the website, we must also be able to adjust and upgrade other programming language skills to suit market needs. Currently, there are many companies that require the services of developers for their website or mobile application needs.

1. Java

Developed in 1990, Java is widely used for various platforms such as websites, mobile, or desktop applications and is open source.

Java is a programming language that implements OOP or object oriented programming. This concept is quite familiar in programming languages because OOP is a concept that can be analogized to the real world or human daily life, so that it can create a directed program flow.

Example syntax from Java:

class Hello {
     public static void main(String[] args) {

To create a Java-based website, several components are needed to run properly. Some of these components are JDK (Java Development Kit), JRE (Java Runtime Environment).

Example of Typescript syntax:

interface User {
  name: string;
  id: number;
class User {
  name: string;
  id: number;
  constructor(name: string, id: number) {
    this.name = name;
    this.id = id;
const user: User = new User("John Doe", 1);

Typescript is a next-level programming language from javascript, by applying the concept of OOP by utilizing classes and interfaces.
