A method named tostring may be a typographical error. toString (different capitalization) may have been intended instead.


Ensure that any such method is intended to have this name. Even if it is, it may be better to rename it to avoid confusion with the inherited method Object.toString.


The following example shows a method named tostring. It may be better to rename it.

public class Customer
	private String title;
	private String forename;
	private String surname;

	// ...

	public String tostring() {  // The method is named 'tostring'.
		return title + " " + forename + " " + surname;
