## Uses of Class
java.lang.StringBuffer

Packages that use StringBuffer
java.io: Provides for system input and output through data streams, serialization and the file system.
java.lang: Provides classes that are fundamental to the design of the Java programming language.
java.text: Provides classes and interfaces for handling text, dates, numbers, and messages in a manner independent of natural languages.
java.util.regex: Classes for matching character sequences against patterns specified by regular expressions.
javax.swing.text.html.parser: Provides the default HTML parser, along with support classes.
