This example shows how to get an instance of ScriptEngine by the engine name. Below we are trying to obtain the GraalVM JavaScript engine.

package org.kodejava.script;

import javax.script.ScriptEngineManager;
import javax.script.ScriptEngine;
import javax.script.ScriptException;

public class GettingScriptEngineByName {
    public static void main(String[] args) {
        ScriptEngineManager manager = new ScriptEngineManager();

        // Obtain an instance of ScriptEngine using the engine name. For
        // example, we get a GraalVM JavaScript engine.
        ScriptEngine engine = manager.getEngineByName("graal.js");

        try {
            engine.eval("print('Hello World');");
        } catch (ScriptException e) {
            e.printStackTrace();
        }
    }
}
