11/7/24 - I've not got a computer sciences background (I'm a biologist!), but I've been learning the bare basics of SQL for a few days. I've applied to two data tech/analyst apprenticeships so I'm trying to get the basics and prep for interviews like this

Personal Chatter

I love that yesterday I was pumped and ready for November and preparing to be productive, and yet today I woke up feeling bad so productivity was low. That's ok, tmr will be better! I also had another ASL class today and the teacher brought us chocolate (and the better thing is that we already know the sign for chocolate before, so we could use that in a sentence today). We've learned about 500 words (do we remember them all? lol, nope), and it's been such a fun class, so I already signed up for the next unit of the class for January.

------------------------------------------------------------------------------

Programming

Even though I didn't feel great today, I did get some stuff done!

LeetCode

Decided to start off with an easy LeetCode question, so I went with Number of Good Pairs and 5 mins later I was done. I previously did the Top Interview 150 questions, but I want more practice with Arrays/Strings, so I'm just doing those types now. Will move onto sorting and binary search trees and linked lists later (once I feel smart again).

Hobby Tracker - Log # 1

Ok, I decided what my full-stack project will be. I want to create a web app in which a user can keep track of different media they want to consume; books, movies, TV shows, and video games. Essentially, I want something that will show me how many things I want to get to (i.e how many books I want to read), and what those things specifically are, and then show me how much of each media type I've completed. For example, I have a spreadsheet of video games I own and I have it show me the % of complete games. I want that, but for all books, movies, shows, and games I enter. Not only that, but for certain media, I want to be able to get a random title from my list. Say I have 20 books I want to read but don't know which to pick. Well, I can ask it to choose a book for me randomly, and I'll read it. That's the basic idea, anyways. Today I spent some time setting up a Trello board to keep track of features I want and functionality I need, and I also started designing the mobile version of the app using Figma. It'll probably be a while before I start coding, but the idea is to have the frontend be built with React, backend with NodeJs, and database be SQL. I'll also be using APIs to get the media info, such as title, genre, etc...This will be the biggest project in terms of scope I've worked on, but hopefully I'll learn a lot.

Crack the Code: Why Learning Java Is Still One of the Smartest Career Moves in 2025

In a world of constantly changing tech trends—where Python, Kotlin, and JavaScript dominate discussions—Java continues to stand strong. And if you're a student or fresher looking to enter the tech industry, learning Java might just be your smartest investment yet.

Why? Because Java is everywhere. From Android apps to enterprise systems, banking software to back-end platforms—Java powers millions of applications used daily. And the demand for skilled Java developers isn't just staying steady; it's growing.

In 2025, Java remains a gateway to building a robust, long-lasting career in software development. And thanks to platforms like Beep, students now have access to hands-on, Java programming courses for beginners that are affordable, practical, and job-oriented.

Why Java Still Rules the Backend World

Some people wrongly assume Java is “old school.” But ask any senior developer, and you’ll hear the same thing: Java is battle-tested, secure, and versatile.

Here’s why companies continue to prefer Java:

Scalability: Perfect for high-traffic apps and large databases

Platform independence: “Write once, run anywhere” is still relevant

Community support: Millions of developers worldwide

Enterprise adoption: Banks, telecoms, logistics firms, and even startups love Java’s stability

Whether you're building a mobile app or designing a cloud-based ERP, Java offers the tools to scale and succeed.

What Makes Java Perfect for Beginners

You don’t need to be an expert to start with Java. In fact, many colleges use Java as a foundation for teaching object-oriented programming (OOP).

As a beginner, you’ll gain core skills that apply across languages:

Variables, data types, control structures

Classes, objects, inheritance, polymorphism

File handling, exception management

Basic UI development using JavaFX or Swing

Introduction to frameworks like Spring (as you advance)

This foundation makes it easier to switch to more specialized stacks later (like Android or Spring Boot) or even pick up other languages like Python or C#.

Where to Start Learning Java the Right Way

While YouTube and free tutorials are good for browsing, structured learning is better for job-readiness. That’s why Beep offers a beginner-friendly Java programming course that’s designed specifically for students and freshers.

What makes this course ideal:

It covers both basic and intermediate concepts

You build real-world projects along the way

You learn how Java is used in interviews and job scenarios

You get certified upon completion—great for your resume

It’s flexible and can be completed alongside college or internship schedules

And if you’re aiming for backend developer jobs, this certification is a strong step in the right direction.

How Java Helps You Land Jobs Faster

Hiring managers love candidates who know Java for one simple reason—it’s practical.

Java-trained freshers can apply for roles like:

Junior Software Developer

Backend Developer

QA Engineer (Automation Testing)

Android App Developer

Support Engineer (Java-based systems)

These roles often mention Java and SQL as core requirements, making it easier for you to stand out if you’ve completed a course and built some small projects.

Explore the latest jobs for freshers in India on Beep that list Java among the top preferred skills.

Build Projects, Not Just Skills

To truly master Java—and get noticed—you need to build and share your work. Here are some beginner-friendly project ideas:

Student registration portal

Simple inventory management system

Expense tracker

Quiz game using JavaFX

File encryption/decryption tool

Host these on GitHub and add them to your resume. Recruiters love seeing what you’ve created, not just what you’ve studied.

What About Java vs. Python?

This is a common question among freshers: Should I learn Java or Python?

The answer: learn based on your goals.

Want to work in data science or AI? Python is ideal.

Want to build robust applications, Android apps, or work in enterprise systems? Java is your best bet.

Also, once you understand Java, learning Python becomes easier. So why not start with the tougher but more rewarding path?

How to Prepare for Java Interviews

Once you’ve got the basics down and completed a project or two, start preparing for interviews with:

Practice problems on platforms like LeetCode or HackerRank

Study key Java topics: Collections, OOP principles, exception handling

Learn basic SQL (many Java jobs also require DB interaction)

Brush up on scenario-based questions

You can also check out Beep’s resources for interview prep alongside your course content.

Final Thoughts: Learn Once, Earn Always

Learning Java isn’t just about getting your first job—it’s about building a lifelong skill. Java has been around for over two decades, and it’s not going anywhere. From web to mobile to enterprise, Java developers are always in demand.

So if you're ready to start your tech journey, don't chase trends. Build a solid base. Start with the best Java course for beginners, practice consistently, and apply with confidence. Because a well-written Java application—and resume—can open more doors than you think.

6. Ensure Career Support and Placement Assistance

A course that helps you learn AI is great—but one that helps you get hired is even better. Look for these features:

Dedicated career services

Resume building workshops

Interview prep and mock tests
