Add @NotNull annotation to all the arguments in IntelliJ

For a method with several arguments, such as this constructor:

    public Chron ( UUID id , UUID trackId , Instant whenCreated , Instant whenLastModified , Instant start , Instant stop , String summary , String notes )

…is there a way to mark all of those parameters with the @NotNull annotation while editing my source code in IntelliJ 2019.2? Repeated pasting seems silly.

Solution

  • Have you tried @ParametersAreNonnullByDefault as explained here.

    enter image description here

    Example usage at package level in package-info.java file.

    @ParametersAreNonnullByDefault
package com.example.acme.backend.data;

import javax.annotation.ParametersAreNonnullByDefault;

    To use this annotation, add the jsr305 library, part of the Google Code FindBugs project. See another Question, What is the status of JSR 305?.
