Invoke method with java reflection with list of parameters

Question

I am currently trying to execute a method via Reflections, but the method parameters are only a list.

List<Object> params = List.of("param1", "param2", 3, "param4");
Method method = getMethod(); //returns the method
AppInstance instance = new AppInstance();
method.invoke(instance, params);

The method looks like:

public void myMethod(String param1, String param2, int param3, String param4){
    //some code
}

but Java treats them like

public void myMethod(List<Object> params){
    //some code
}

The problem is that the length of the parameters varies, the method can have any number of parameters.

Is there a way to solve this problem?

Answer 1

try this

Object[] params = new Object[]{"param1", "param2", 3, "param4"};
Method method = getMethod();
AppInstance instance = new AppInstance();
method.invoke(instance, params);
