public class DvdName { private String titleName; public DvdName(String titleName) { this.setTitleName(titleName); } public final void setTitleName(String titleNameIn) { this.titleName = titleNameIn; } public final String getTitleName() { return this.titleName; } public void setNameStarsOn() { this.setTitleName(this.getTitleName().replace(' ','*')); } public void setNameStarsOff() { this.setTitleName(this.getTitleName().replace('*',' ')); } public String toString() { return ("DVD: " + this.getTitleName()); } }

The class DvdName uses a property pattern. The DvdName class has a getter (getTitleName()) and a setter (setTitleName()) for the titleName property. The setter method sets the titleName property. The setter method also allows for validation. The property titleName is a private field. Using a property pattern is a good way to create a class.
