Below, we define a method which uses Scala reflection to get the runtime. There are three steps that must be followed to use these classes. The required classes for reflection are provided under package which is essential in order to understand reflection. In addition, Java reflection is also unable to recover runtime type info of. The reflection classes, such as Method, are found in.
JAVA REFLECTION GET METHOD HOW TO
In this short article, we'll take a quick look at how to invoke methods at runtime using the Java Reflection API. Reflection is an API that is used to examine or modify the behavior of methods, classes, and interfaces at runtime. If you have a few years of experience in the Java ecosystem, and you're interested in sharing that experience with the community (and getting paid for your work of course), have a look at the "Write for Us" page. The .get (Object obj) method returns the value of the field represented by this Field, on the specified object. Method fooMethod getMethod ( new MyObject ().foo () ) // returns method 'foo' in MyObject The obvious way is to use the name of the method as a string: Method fooMethod ('foo') but I want to avoid this because if I rename foo () that code will stop working or I have rename the string in all the places where it is used.
