I am trying to get a method of a class using reflection where argument of that method is sometimes a primitive type or any Object.
Example:
public class A {
public void display(short a){
System.out.println(a);
}
}
import java.lang.reflect.InvocationTargetException;
import java.lang.reflect.Method;
import com.rexample.model.A;
public class ReflectionExample {
public static void main(String[] args) throws NoSuchMethodException, SecurityException, IllegalAccessException, IllegalArgumentException, InvocationTargetException {
ReflectionExample example=new ReflectionExample();
example.print();
}
public void print() throws NoSuchMethodException, SecurityException, IllegalAccessException, IllegalArgumentException, InvocationTargetException {
String nameOfTheMethod="display";//Assume name of the method is display
short v=10;//Assume primitive type is short
Object value=v;
Method method=A.class.getDeclaredMethod(nameOfTheMethod,value.getClass());
method.invoke(new A(),value);
}
}
And i am getting the error:
Exception in thread "main" java.lang.NoSuchMethodException: com.rexample.model.A.display(java.lang.Short)
at java.lang.Class.getDeclaredMethod(Class.java:2130)
at com.rexample.test.ReflectionExample.print(ReflectionExample.java:34)
at com.rexample.test.ReflectionExample.main(ReflectionExample.java:27)
Above code is just a small example of a larger program that i am currently building where i cannot able to get method of parameter type short
or any other primitive type.
I cannot able to directly use short.class or Short.TYPE in my code , Since i am trying to do in a more generic way.
Is there any way to solve my issue for parameter of primitive type and of any objects?
