Is it possible to make something like this? I know that implements cannot be in the <>, but I want to restrict the T to be Serializable somehow.
public class Clazz<T implements Serializable> {
...
}

As per the Java Object Serialization Specification, we can use the writeObject() method from ObjectOutputStream class to serialize the object. On the other hand, we can use the readObject() method, which belongs to the ObjectInputStream class, to perform the deserialization.
Whenever you want to restrict the type parameter to subtypes of a particular class you can use the bounded type parameter. If you just specify a type (class) as bounded parameter, only sub types of that particular class are accepted by the current generic class.
Advantage of Java Generics 1) Type-safety: We can hold only a single type of objects in generics. It doesn?t allow to store other objects. Without Generics, we can store any type of objects. List list = new ArrayList();
public class Clazz<T extends Serializable> {
...
}
Just use extends instead of implements.
