Internet is a free college.

For example, if I need to determine how ‘Polymorphism works in Java’, I don’t need to get a degree to master this concept.

Similarly, ‘Stack Overflow’ is an excellent free resource for those who want to be computer scientists.

There are tremendous online free tutorials about programming and such skills.

Even many universities like MIT have free course portals where people can learn a lot free of cost.

I admit that there might be certain expertise that may require college — like Civil Engineering — but at the same time, I hope a day will come when the education will be free for all.

In a nutshell, if you have the passion to do something, internet can be a cheap and efficient resource.

⭐️6 Tips to Study Coding Effectively⭐️
by UFV Academic Success Centre

1. Don’t just read the code example—Type it out and then create a similar one
🔹 A code sample is the representation of the idea or program.
🔹 Type it in your own words to understand how the five components are working together.
🔹 Create a similar sample to understand the abstract of the program.
🔹 Try some code challenges from some well-known websites, such as leetcode, codewars, and
topcoders.

2. Practice and keep track of what you have learned
🔹 Practice makes perfect.
🔹 As a programmer, you often can have some repetitive tasks. Keeping track of what you learn will
help you quickly refer back to the tasks you have done.
🔹 Document what you have learned. Documentation is a good resource to help you look up the
algorithm/solution and repetitive tasks easily and increase your productivity rapidly.

3. Try to create, then build your own program
🔹 Apply what you have learned to a real-life example.
🔹 Building your own program brings you to the next level of program abstract and will help you feel
satisfied and accomplished with what you have learned.
🔹 When you come up with a solution, try a different approach. There is more than one right way to
do something, and searching for different solutions will help you develop your problem solving
skills.

4. Learn how to research and solve problems
🔹 Search for topics by specific keywords.
🔹 Learn how to research your problem when you get stuck. Some websites may help, such as
stackoverflow, stackexchange, github, and forums.
🔹 If you find a solution online, make sure you understand every line of code. You will learn more this
way rather than just copying and pasting it into your project.

5. Take a break while debugging
🔹 Consider taking break to clear your mind when you encounter difficult bug.
🔹 Stepping away for a few hours will allow you to return with a fresh perspective.

6. Things to avoid
🔹 Perfection: As a beginner, improving your coding skills and problem solving are more important
than making your code perfect. Seeking perfection will cause you to procrastinate instead of
progress. Remember that mistakes are opportunities to learn.
🔹 Comparison: Never compare your code style/knowledge with anyone else. You will end up being
disappointed and demotivated. Practice and trust yourself.
🔹 Complexity: Learn how to break a problem into smaller problems, so you can conquer it more
easily.
A good programmer is able to make a program simpler and less complex. Make it work first, then
make it right, finally make it fast. “Simplicity is the ultimate sophistication,” said Leonardo Da Vinci.

Insights on the Current Job Market

It's no secret, folks. OFFCAMPUS hirings are dwindling this year, and it's causing some serious ripples. Last year, the scenario was quite different, but now, it's a whole new ball game.

🔍 Companies are leaning towards on-campus hires, leaving OFFCAMPUS opportunities limited. No Microsoft Engage this year, which is a bit of a letdown.

📉 Even on campus, companies are playing it cautious with headcounts. Last year, Amazon scooped up an average of 20-30 students from top-notch colleges. This year, the story's different.

📜 Pre-Placement Offers (PPOs) are scarcer. Big tech players aren't extending them to everyone, even with glowing feedback.

🗓 Joining dates for 2023 grads have been pushed, giving 2024 grads a run for their money. The market's teeming with talent, and companies are preferring the ones ready to hit the ground running.

📚 With the rise of edtech and heightened student expectations, competition is fierce. Some score multiple offers, while others face a dry spell. Inequality is on the rise.

💡 For the graduating class, here's my take: don't let the stress get to you. This wave is hitting everyone, even the mighty IITs and NITs. Expand your skill set. If you're a DSA whiz, dabble in development and master it.

⏳ You've got time. Use it wisely. Your placement is on the horizon, whether it's immediate or a bit down the road.

🚀 Focus on development. Target promising startups. Secure a position, and in a year or so, reassess the landscape. The market's bound to bounce back.

🛠 Freelance projects? Definitely worth considering. They not only offer a solid backup but also let you create something with your own stamp on it.

Remember, be proactive, diversify your skills, and most importantly, look after your well-being. Your health is your greatest asset. 💪🌟

Important topics of Object Oriented Programming System

1. Classes and Objects:

-> Static methods and variables.

A few advanced topics :-

Composition and Aggregation:
Combining objects to create more complex structures.

UML (Unified Modeling Language):
A visual language for modeling software systems.
Class diagrams, sequence diagrams, and use cases.

Method Overriding vs. Method Overloading:
Understanding the differences between these two concepts.

Abstract Classes vs. Interfaces:
