Parse JSON in Java using Jackson

README.md

This is the sample source code for my blog at https://blog.petehouston.com/simple-guide-to-parse-json-in-java/

Article.java

public class Article {
    private String title;
    private String author;
    private String url;
    private List<String> tags;

    public Article() {
    }

    public Article(String title, String author, String url, List<String> tags) {
        this.title = title;
        this.author = author;
        this.url = url;
        this.tags = tags;
    }

    public String getTitle() {
        return title;
    }

    public void setTitle(String title) {
        this.title = title;
    }

    public String getAuthor() {
        return author;
    }

    public void setAuthor(String author) {
        this.author = author;
    }

    public String getUrl() {
        return url;
    }

    public void setUrl(String url) {
        this.url = url;
    }

    public List<String> getTags() {
        return tags;
    }

    @Override
    public String toString() {
        return "Article{" +
                "title='" + title + '\'' +
                ", author='" + author + '\'' +
                ", url='" + url + '\'' +
                ", tags=" + String.join(", ", tags) +
                '}';
    }
}
