How to call a method with generic array parameters through java reflection

recently I was watching an algorithm course where the teacher used cPP"s template and function pointers to complete an implementation, so I tried to use java to do it through reflection and generics, but there was a problem.

I want to dynamically test various sort functions in SortClass through java reflection and generics, so I don"t know how to solve the parameters of the getmethod method and the invoke method. The implementation I wrote keeps reporting parameter exceptions

Code

class SortClass<T extends Comparable>{
//
public void selectSort(T[] a){
    for(int i = 0; i < a.length; iPP){
        int min = i;
        for(int j = i+1; j < a.length; jPP){
            if(a[j].compareTo(a[min]) < 1){
                swap(a,j,min);
            }
        }
    }
}
//
public void swap(T[] arr, int a, int b){
    T temp = arr[a];
    arr[a] = arr[b];
    arr[b] = temp;
}
//
public void testSort(String sortName,Object[] a){
    long startTime = System.currentTimeMillis();
    try {
        Method method = this.getClass().getMethod(sortName,Object[].class);
        method.invoke(this,a);
    } catch (NoSuchMethodException e) {
        System.out.println(e.getMessage()+" not find");
    } catch (IllegalAccessException e) {
        e.printStackTrace();
    } catch (InvocationTargetException e) {
        e.printStackTrace();
    }
    long endTime = System.currentTimeMillis();

    System.out.println(sortName + "use time:" + (endTime-startTime));
}

}

I hope there are some improved methods or code to complete this implementation.

in the invoke method, convert a strong to object
or the array will be parsed into parameters instead of an entire array as a parameter
