[Suresh Appagundi]

Hi,

How to pass primitive types, Array types and user define type to a method, when invoking method using Java reflection api.

Any sample code or any related links will be very helpful

thanks in advance.

Have you worked through the Java Tutorial, specifically the section on reflection? It has a number of examples.

Wrap them in the corresponding wrapper classes (int -> Integer, char -> Character, etc.) and the reflection API will automatically unwrap them.

--------------------------------------------
Suppose i have

public void set(int i){
}

public void set(Integer i){
}

And if i wrap the primitive int into Integer wrapper, which of the above methods will be considered. Actually the second one. But i want the first method to invoke. Now how do i do it.

Every method is represented by a distinct "java.lang.reflect.Method" object. You get the Method object for the specific method you want to call, and you invoke it. In other words, you yourself choose between the methods.

If you had worked through the tutorial linked above, you would know this already!
