Sorry for troubling everyone with my questions these past few days, but I keep bumping into all these weird little problems.
The code below, is a sort of minor reflective program that runs methods after reading classes.
try {
//getclass is a class named "Example"
<strong>Object instance = getclass.newInstance();</strong>
//Is the name of a method inside "Example"
String methodname = "returnconcat";
//returnconcat needs 2 strings.
Class[] parametertypes = new Class[] {String.class, String.class};
//Problem - Says its not an instance, so I have to make an
//instance
//Thats what object instance is. But I cant turn the object
//into a method.
<strong>Method run = getclass.getMethod(methodname, parametertypes);</strong>
String result;
Object[] params = {"hello", "world"};
result = (String) run.invoke(run, params);
} catch (Exception e) {
e.printStackTrace();
}
The problem I'm getting is that when I run this line of code:Method run = getclass.getMethod(methodname, parametertypes);
I get a:
java.lang.IllegalArgumentException object is not an instance of declaring class.
So when I make an instance of that with Object instance = getclass.newInstance(); I have no clue what to do with it because it's an object and if I try to cast it as a method, I get a Casting error. Can anybody help me get this to work?
