This example shows how to compile and run Java code.

import cjdk
import subprocess

java_source = """
public class Hello {
    public static void main(String[] args) {
        System.out.println("Hello, World!");
    }
}
"""

with open("Hello.java", "w") as fp:
    fp.write(java_source)

with cjdk.java_env(vendor="temurin-jre", version="17.0.3"):
    subprocess.run(["javac", "Hello.java"], check=True)
    subprocess.run(["java", "Hello"], check=True)
