Packages that use Boolean
java.awt.font Provides classes and interface relating to fonts. 
java.lang Provides classes that are fundamental to the design of the Java programming language. 
java.util Contains the collections framework, legacy collection classes, event model, date and time facilities, internationalization, and miscellaneous utility classes (a string tokenizer, a random-number generator, and a bit array).

javax.management.relation Provides the definition of the Relation Service. 
javax.management.remote Interfaces for remote access to JMX MBean servers. 
javax.management.timer Provides the definition of the Timer MBean. 
javax.swing Provides a set of "lightweight" (all-Java language) components that, to the maximum degree possible, work the same on all platforms. 
javax.swing.filechooser Contains classes and interfaces used by the JFileChooser component. 
javax.swing.plaf.basic Provides user interface objects built according to the Basic look and feel. 
javax.tools Provides interfaces for tools which can be invoked from a program, for example, compilers.
