What is the difference between field, variable, attribute, and property in Java POJOs?

When referring to internal private variables of Java POJOs that have getters/setters, I've used the following terms:

• field
• variable
• attribute
• property

Is there any difference between the above? If so, what is the correct term to use? Is there a different term to use when this entity is persisted?

From Oracle's Java Glossary:

• variable

  • An item of data named by an identifier. Each variable has a type, such as int or Object, and a scope. See also class variable, instance variable, local variable.

• instance variable
  • Any item of data that is associated with a particular object. Each instance of a class has its own copy of the instance variables defined in the class. Also called a field. See also class variable.

• class variable
  • A data item associated with a particular class as a whole--not with particular instances of the class. Class variables are defined in class definitions. Also called a static field. See also instance variable.

• field

  • A data member of a class. Unless specified otherwise, a field is not static.

• property

  • Characteristics of an object that users can set, such as the color of a window.

• attribute

  • Not listed in the glossary.
