The code below eliminates spaces at the beginning or end of a name entered by the user, it tries to remove the spaces inside the setter method of a bean. It is not recommended that a bean modifies its data instead of simply holding it. The getter returns different data than that set by the setter.
private String name;public void setName(StringName) { this.name = name.trim(); }public void String getName() { return this.name; }
In general, a bean should not modify its data, it is a data container, not business logic. The trimming makes sense in the controller where the input occurs or in the logic where the spaces are not wanted.
person.setName(textInput.getText().trim());
