void returns no data type

Void doesn't have any return type as by its name it is empty. It is used in constructor methods as they can never have a return type. void is used when there is no return type that needs to be mentioned. This method can be used anywhere with any other method and anywhere in the program.

For Example:

The method displayData() does not have a return type as shown by the use of the void keyword.

public class Data {

private String title;
private String author;
private String publisher;

public Data(String title, String author, String publisher)
{
this.title = title;
this.author = author;
this.publisher = publisher;
}

public void displayData()
{
System.out.println("Title: " + title);
System.out.println("Author: " + author);
System.out.println("Publisher: " + publisher);
}
}
