JAVA相对路径、绝对路径

public class FilePathGetDemo {

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

//当前路径
File f = new File(".");
String absolutePath = f.getAbsolutePath();
System.out.println(absolutePath);

//绝对路径
//FileReader reader = new FileReader("C:\\MavenWorkspace\\TestJs\\src\\yourFile.js");

//相对路径
FileReader reader = new FileReader("src\\mytest.js");

engine.eval(reader);
reader.close();
} catch (Exception e) {
e.printStackTrace();
}
}
}
