public class Demo1 {
    //we will see how we can use Annotations in Java and create Are own     annotations
    public static void main(String[] args) {
        @SuppressWarnings("unchecked")

        Cat cat1 = new Cat("kasem");

//        System.out.println(cat.getClass().isAnnotationPresent(veryImportant.class));
                     for(Method  meethod : cat1.getClass().getDeclaredMethods() ){
                        if( meethod.isAnnotationPresent(Runimmedietly.class))
                        {
                            meethod.setAccessible(true); // Make the method accessible
                            meethod.invoke(cat1);// output should hello world

                        }

                     }

hey guys im trying to invoke the method of the object cat1 but it's giving me this error java: unreported exception java.lang.IllegalAccessException; must be caught or declared to be thrown

package optionalsjJava;

import annotationsJava.*;

@veryImportant
public  class Cat {
//    @veryImportant //'@veryImportant' not applicable to field
        String name;
        int i;

    public Cat(String name) {
        this.name = name;


    }
    @Runimmedietly
    public static void number() {
        System.out.println("hello world");    }
