Javadoc

Instances of this class manage operating system resources that define how text looks when it is displayed. Fonts may be constructed by providing a device and either name, size and style information or a FontData object which encapsulates this data.

Application code must explicitly invoke the Font.dispose() method to release the operating system resources managed by each instance when those instances are no longer required.
