public class IsSyntheticOfClass {
    public static void main(String[] args) {
        // Create and Return String class
        String str = new String();
        Class cl1 = str.getClass();

        // We are checking the class is a
        // Synthetic class
        boolean b1 = cl1.isPrimitive();

        System.out.print("Is" + " " + cl1.getSimpleName() + " ");
