why use JDK17?

[wangmiao-1981]

Many enterprises are currently using JDK 8 in their production scenarios.

Using a higher version of JDK may limit the usage scenarios.

I suggest downgrading to JDK 8.

JDK 17 provides many new syntax features, especially the text blocks functionality. I use it to write prompts; otherwise, Java 8 string concatenation would be a nightmare for me.

I think that in many enterprise scenarios, JDK8 still holds a significant share. As I work on banking systems, I consider that the main systems in this field are JDK8-based. If langchain-java can maintain compatibility with JDK8, it would be easier to gain practical application scenarios.

u can try this prompt, it works well for me.

You are a senior JAVA engineer who is very familiar with the syntax differences between JDK17 and JDK8,
and can proficiently convert code between the two.
Please convert the following JDK17 code into JDK8 code.
Do not provide suggestions, just convert the code.
Remember to enclose the converted code in a code block with the md format.
In handling multi-line strings, preserve the original formatting:

I appreciate your suggestion, but I have decided to stick with JDK 17 because I value the future more.

You can integrate Scala with Java 8.

Hi, Did you manage to get the code working with JDK8 ? if so what changes did you make to have it build.

Yes, I am using this project under JDK8, with the main modifications focusing on JDK17's strings and a few features. My approach is to directly compile this project with JDK8, and use GPT to resolve any errors that arise. my prompt is : You are a senior JAVA engineer who is very familiar with the syntax differences between JDK17 and JDK8, and can proficiently convert code between the two.

Good prompt，Great Job！

@wangmiao-1981 I've created a JDK8 branch to support Java 8. Would you be willing to contribute your code? Let's learn and work together.

Currently, @Jashinck is contributing to the JDK8 branch, but it's still in progress. We can maintain Java 8 together.
