Night Keyboard Typing Coding

When I first learned to program, it was grasping if statements that helped it all click into place for me. Once you can use if statements, you can build all kinds of useful and interesting tools. Moreover, this is a basic programming structure that you’ll use in nearly every language.

In this post, we’ll explore how to use if statements in Java.

Understanding if statements in Java

So, just what is an if statement in Java?

Essentially, an “if statement” is what you use for “flow control.” If statements allow for

Understanding variables in Java – Android Authority

Variables are the bread and butter of coding. Without variables, apps would have no interactivity and no way of manipulating information. Therefore, learning about variables in Java should be among the very first things you do when picking up the language. In this post, you’ll find everything you need to know.

What are variables in Java?

The best way to understand variables is to think back to math lessons. You may recall solving algebra “problems” that looked something like this:

If 3 + n = 5, then what is n?

Of course, the answer is n = 2.

Loops in Java

A loop is a structure in programming that allows you to run the same section of code over and over. This can be used when you want to perform an iterative task (like counting, or sorting through a list) or to create an ongoing, cyclical experience for the user (as in a game loop). In this post, we will examine how to use loops in Java.

There are three types of loops in Java:

  • For loops
  • While loops
  • Do-while loops

Starting with for loops, this is the best

Classes in Java

One of the features that make Java so powerful, is its object-oriented structure. This means that Java uses classes and objects to create more scalable, modular, and organized code. This can be a complex concept to wrap your head around as a new developer, though. So in this post, we’re going to examine how to use classes in Java.

how to use loops in Python

In this post, you will learn how to use loops in Python.

Loops are a commonly used structure in programming that allows you to repeat a block of code a set number of times, or until you meet a particular condition.

This is useful for many reasons. For example, if you are building a game, then you might want the bulk of your code to continuously “loop” while you update the position of enemies and check for player inputs. If you build a game in Pygame, then “game loop” will be one of the most important aspects of that

How to install Java

Whether you want to begin coding in Java or just wish to run Java apps, you first need to learn how to install Java. In this post, we’ll see how to do that.

Why do you need to install Java?

Programmers would describe Java as both being “compiled” and “interpreted.” This means that Java code can’t be understood natively by the computer but must first be “compiled” to a Java Bytecode. This Bytecode can then be run by any device that has the “Java Virtual Machine” installed. Alternatively, the code can be translated by software installed onto your machine.
