Java 中调用JavaScript

JDK1.6中加入了对JavaScipte脚本的调用方法，代码如下

 

public static void main(String[] args) throws Exception {
        ScriptEngineManager mgr = new ScriptEngineManager();
        ScriptEngine engine = mgr.getEngineByName("JavaScript");
        String js = "23+3*32/2-65";
        Object eval = engine.eval(js);
        System.out.println(eval);

        System.out.println(23+3*32/2-65);
    }
