DAO Pattern in Java Sample

DAO Pattern in Java

In order to continue the topic of database connectivity in Java, it is necessary to look at the DAO pattern, which facilitates operation with the database.

The main idea of the Data Access Object (DAO) pattern is to hide all backend operations of the connection to the database and unite them in one main class. This may be necessary when the program consists of multiple entities interconnected with each other, and it would be very complex and of poor practice to make connection from each entity every time.

Understanding Indentation in Python

In the programming world, indentation has been essential for structuring code. Unlike most languages, which use braces and keywords to mark code blocks, Python uses whitespaces and indents only to distinguish code blocks as they return. 

Such a feature is crucial to how Python programs are written, read, and executed, as well as the heart of the role of the language in the world of programming. This article unravels the mysteries of space and invades the indentation of Python, importing its rules, benefits, and shortcomings and giving the techniques for their use.

Gravity Calculator Java Example

GRAVITY CALCULATOR JAVA TASK:

Create Java gravity calculator, able to determine the object’s final position after falling through the Earth’s atmosphere through the predetermined time. The initial parameters include: gravity (-9.81), falling time (10 seconds), as well as initial position and initial velocity of the object (both set to 0 by default). However the user should be able to modify the last 3 parameters according to his liking, with the calculator providing him with corresponding final position each time one of parameters changes.

Law of Conservation of Energy Problems with Solutions

Problem 1:

An intrepid physics student decides to try bungee jumping. She obtains a cord that is h=12 m long and has a spring constant of K=3.00 * 10^2 N/m. When fully suited, she has a mass of m=69 kg. She looks for a bridge to which she can tie the cord and step off. Determine the minimum height of the bridge L, that will allow her to stay dry (that is, so that she stops just before hitting the water below). Assume air resistance that is negligible.
