why use JDK17? about langchain-java HOT 8 CLOSED

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

from langchain-java.

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 can integrate Scala with Java 8.

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.

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.

@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.
