How to optimize Java code

Optimizing the code for speed and reducing memory consumption is usually a secondary concern. We will look at how to prevent these problems.

Over the years, I’ve seen a lot of code and worked on a lot of projects, new or long-running. Optimizing for speed and reducing memory requirements usually comes into play only in case of problems with a lack of it, or in the event of a drop in performance. Then we look for the simplest solution with minimal additional delay of the project. It is not always possible to quickly and easily eliminate the problem. This often requires re-architecting and changing code in many places. Changing the architecture is quite a painful and difficult matter. It usually comes at the end. Here, it is an advantage if there is not a lot of code duplication in the project, as it simplifies and speeds up changes.

In the following article

would point out how to write more efficient and faster code right from the start. This will avoid possible poland phone number data delays and code optimizations during the project. The time consumption of writing an already efficient code is the same as writing an inefficient one. For this reason, it is more advantageous to write optimized code from the beginning.

Basic recommendations

We use a profiler to identify problem areas. It identifies the places where our code spends the most time. Even small changes with use these platforms to share a large number of repetitions can affect performance. According to the profiler results, the most common bottlenecks are chain work and long cycles. We should avoid cg leads using variables of type String. Instead, we can use a numeric value or an enumeration. String manipulation is more complicated and time-consuming. Therefore, it is more advantageous to define object IDs and object types.
