Java dynamic compilation execution code example

In some cases, we need to dynamically generate java code, compile it dynamically, and then execute the code. Java API provides corresponding tools (Java compiler) to realize dynamic compilation. Let's introduce how to realize dynamic compilation of Java code through Java compiler through a simple example.

1、 Get javacompiler

Get the java compiler provided by JDK. If no compiler is provided, null is returned;

2、 Compile

When other codes are referenced in the source code to be compiled, we need to set the reference code path to - classpath, otherwise the compilation will fail.

3、 Execute

4、 Complete code

5、 Testing

test result

summary

The above is all about the Java dynamic compilation and execution code example in this article. I hope it will be helpful to you. Interested friends can continue to refer to this website:
