How can store the intermediate code of an entire script

import javax.script.Compilable;
import javax.script.CompiledScript;
import javax.script.ScriptEngine;
import javax.script.ScriptEngineManager;

public class CompilableDemo {

public static void main(String[] args) throws Exception {
ScriptEngineManager manager = new ScriptEngineManager();
ScriptEngine engine = manager.getEngineByName("js");

Compilable jsCompile = (Compilable) engine;
CompiledScript script = jsCompile.compile("function hi () {print ('www.java2s.com !'); }; hi ();");

for (int i = 0; i < 5; i++) {
script.eval();
}
}
}
//www.java2s.com !www.java2s.com !www.java2s.com !www.java2s.com !www.java2s.com !
