Get Started With Profiling in IntelliJ IDEA

Sometimes your app works, but you want to increase performance by boosting its throughput or reducing latency. Other times, you just want to know how code behaves at runtime, determine where the hot spots are, or figure out how a framework operates under the hood.

Some of these details can be provided at design time, as IntelliJ IDEA provides you with all sorts of clues that can be produced statically. Of course, you cannot learn about all the bugs and inefficiencies by just looking at the code, because things get more complicated at runtime. Verifying any guesses you have can prove to be a tough task without the right tools at hand.

Two particularly helpful tools for examining the program at runtime are the debugger and profilers.

The debugger is very precise and gives you full and granular control over the execution of the program, which allows you to reproduce intricate failure conditions.

The profiler, on the other hand, offers a bird’s eye view of arbitrarily large execution chunks. It does not interfere with the running program, nor does it provide granular data like the debugger does. However, it can collect valuable information no other tool can, which is why in this post we are going to take a look at the capabilities of profilers.

IntelliJ IDEA provides integration with the following profilers:

Java Flight Recorder – a standard profiling tool shipped as part of the JDK.

Async profiler – a very accurate profiler that can also collect native call and memory allocation data.

Both of these profilers use sampling, so the overhead is very low – close to running the program without the profiler. You can attach either of them to a Java process and view the profiling report directly from IntelliJ IDEA.

IntelliJ IDEA for Beginners - Learn IntelliJ IDEA from Scratch

Complete IntelliJ IDEA Course for Beginners

IntelliJ IDEA for Beginners - Learn IntelliJ IDEA from Scratch

How to become an expert IntelliJ IDEA Developer

This course takes is specifically designed for developers that either don’t have any previous experience using an Integrated Development Environment (IDE) tool or experienced IDE developers new to Intellij IDEA (e.g. experienced Eclipse developers).

With that said, even if you’re an experienced Intellij IDEA developer you might still get something out of the course. This is specially true since this course is (almost exclusively) based on version 2019 which introduced features that you may not yet me familiar with. So please still check it out!

Also, no particular programming language knowledge is assumed since Intellij IDEA is pretty much language agnostic and supports many different programming languages.

Sections I, II and III are mandatory and must be taken in order.

Section IV is specifically designed for experienced Eclipse developers interested in a quick migration path to IntelliJ

The rest of the sections (V, VI, VII and VIII) can be taken in any order as they’re self contained. I highly recommend that you still taken them all, particularly if you don’t have any previous Intellij IDEA experience.

How to start an electric scooter facility/fleet in a university campus/IT park

Are you leading an organization that has a large campus, e.g., a large university? You are probably thinking of introducing an electric scooter/bicycle fleet on the campus, and why wouldn’t you?

Introducing micro-mobility in your campus with the help of such a fleet would help the people on the campus significantly. People would save money since they don’t need to use a car for a short distance. Your campus will see a drastic reduction in congestion, moreover, its carbon footprint will reduce.

Micro-mobility is relatively new though and you would need help. You would need to select an appropriate fleet of vehicles. The people on your campus would need to find electric scooters or electric bikes for commuting, and you need to provide a solution for this.

To be more specific, you need a short-term electric bike rental app. With such an app, you will be able to easily offer micro-mobility to the people on the campus. We at Devathon have built Autorent exactly for this.

What does Autorent do and how can it help you? How does it enable you to introduce micro-mobility on your campus? We explain these in this article, however, we will touch upon a few basics first.

Micro-mobility: What it is

micro-mobility

You are probably thinking about micro-mobility relatively recently, aren’t you? A few relevant insights about it could help you to better appreciate its importance.

Micro-mobility is a new trend in transportation, and it uses vehicles that are considerably smaller than cars. Electric scooters (e-scooters) and electric bikes (e-bikes) are the most popular forms of micro-mobility, however, there are also e-unicycles and e-skateboards.

You might have already seen e-scooters, which are kick scooters that come with a motor. Thanks to its motor, an e-scooter can achieve a speed of up to 20 km/h. On the other hand, e-bikes are popular in China and Japan, and they come with a motor, and you can reach a speed of 40 km/h.

You obviously can’t use these vehicles for very long commutes, however, what if you need to travel a short distance? Even if you have a reasonable public transport facility in the city, it might not cover the route you need to take. Take the example of a large university campus. Such a campus is often at a considerable distance from the central business district of the city where it’s located. While public transport facilities may serve the central business district, they wouldn’t serve this large campus. Currently, many people drive their cars even for short distances.

As you know, that brings its own set of challenges. Vehicular traffic adds significantly to pollution, moreover, finding a parking spot can be hard in crowded urban districts.

Well, you can reduce your carbon footprint if you use an electric car. However, electric cars are still new, and many countries are still building the necessary infrastructure for them. Your large campus might not have the necessary infrastructure for them either. Presently, electric cars don’t represent a viable option in most geographies.

As a result, you need to buy and maintain a car even if your commute is short. In addition to dealing with parking problems, you need to spend significantly on your car.

All of these factors have combined to make people sit up and think seriously about cars. Many people are now seriously considering whether a car is really the best option even if they have to commute only a short distance.

This is where micro-mobility enters the picture. When you commute a short distance regularly, e-scooters or e-bikes are viable options. You limit your carbon footprints and you cut costs!

Businesses have seen this shift in thinking, and e-scooter companies like Lime and Bird have entered this field in a big way. They let you rent e-scooters by the minute. On the other hand, start-ups like Jump and Lyft have entered the e-bike market.

Think of your campus now! The people there might need to travel short distances within the campus, and e-scooters can really help them.

How micro-mobility can benefit you

benefits-micromobility

What advantages can you get from micro-mobility? Let’s take a deeper look into this question.

Micro-mobility can offer several advantages to the people on your campus, e.g.:

  • Affordability: Shared e-scooters are cheaper than other mass transportation options. Remember that the people on your campus will use them on a shared basis, and they will pay for their short commutes only. Well, depending on your operating model, you might even let them use shared e-scooters or e-bikes for free!
  • Convenience: Users don’t need to worry about finding parking spots for shared e-scooters since these are small. They can easily travel from point A to point B on your campus with the help of these e-scooters.
  • Environmentally sustainable: Shared e-scooters reduce the carbon footprint, moreover, they decongest the roads. Statistics from the pilot programs in cities like Portland and Denver showimpressive gains around this key aspect.
  • Safety: This one’s obvious, isn’t it? When people on your campus use small e-scooters or e-bikes instead of cars, the problem of overspeeding will disappear. you will see fewer accidents.
