Why am I getting extra stuff when looping through methods?

Okay not sure what is going on. I am using Java Reflection and iterating and inspecting methods of a particular class. Below is the following code I am using:

public void test(){

    Class useCases = Car.class;

    Method[] methods = useCases.getMethods();
    Integer[] numbers = {2, 5};
    String[] numberStrings = {"2", "5"};
    for(int i=0; i<methods.length; i++){
        try {
            System.out.print(methods[i].getName());
            Method method = useCases.getMethod(methods[i].getName(), new Class[]{String.class, Integer.class});
            Object returnV = method.invoke(new Car(), numberStrings[i], numbers[i]);
            System.out.print(returnV.toString() + "\n");
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

Car Class:

public String getNumber(String number, Integer times){
    return times == 2 ? number : null;
}

public String getNumber1(String number, Integer times){
    return times == 5 ? number : null;
}

It loops through fine printing out the first two methods and the return value fine, but then it continues and prints out a wait() and not sure why and I am getting the following error:

java.lang.NoSuchMethodException: sample.Car.wait(java.lang.String, java.lang.Integer)

Any help as to why the loop does not end with just printing and returning the values for the only two methods in that Car class.
