java pojo vs kotlin data class

song.java

// kotlin data class (equals/hashcode/copy available)
data class Song (val name: String, val artist: Artist, var length: Int?)
  
// pojo with 1 of the Song properties for brevity (and no equals/hashcode)
public class Song {
  private String name;

  public Song(String name) {
    this.name = name;
  }

  public String getName() {
    return name;  
  }
  
  public void setName(String name) {
	  this.name = name;
  }
}
