'@Serial' annotation could be used

Reports methods and fields in the Serializable and Externalizable classes that are suitable to be annotated with the java.io.Serial annotation. The quick-fix adds the annotation.

Example:

class Main implements Serializable { private static final long serialVersionUID = 7874493593505141603L; private void writeObject(ObjectOutputStream out) throws IOException { } }

After the quick-fix is applied:

class Main implements Serializable { @Serial private static final long serialVersionUID = 7874493593505141603L; @Serial private void writeObject(ObjectOutputStream out) throws IOException { } }

Example:

class Main implements Externalizable { protected Object readResolve() throws ObjectStreamException { return "SomeObject"; } }

After the quick-fix is applied:

class Main implements Externalizable { @Serial protected Object readResolve() throws ObjectStreamException { return "SomeObject"; } }

For more information about all possible cases, refer the documentation for java.io.Serial.

This inspection depends on the Java feature '@Serial annotation' which is available since Java 14.
