Improving performance or reducing memory footprint is important to reducing the cost of running Java applications, especially when using public cloud platforms. Here are some ways to accomplish this!

1/7
Often the best choice would be to upgrade to the latest JDK version, which provides significant runtime benefits.

Improving startup is often a focus for Java applications. One of the easiest ways of improving startup is by using AppCDS!

4/7
Choosing the right GC for your application is important as well. Let's look at the comparative performance goals of the currently available GCs in the JDK.

5/7
Measuring the impact of performance changes is critical to ensure they are having the expected impact, as well as finding areas where performance might need to be improved.

Tools like JDK Flight Recorder are an excellent choice for this.

Here is your Friday #SipOfJava thread! 🧢🐈

Needing to automate a task? Consider writing it in Java! Recent changes, and some long-existing APIs, have made Java a practical choice for writing small utility apps. Let's take a look!

1/7
Added in JDK 11, the java launcher can now directly launch single-file source-code applications. Making it easier to develop and launch small utility apps.

2/7
Local-variable type inference (var) was added in JDK 10. var can make it easier when working with complex types (i.e. when generics are involved) and easier to define variables in applications.

Records πŸ’Ώ are one of the most exciting changes that have come to Java since Lambdas and Streams in Java 8. Let's review some of the key benefits and library integrations for Records.

2/6
Serialization is one of the scariest areas in Java, with a lot of easy to overlook traps that could leave your application vulnerable. Records address a lot of common serialization vulnerabilities.
