org.apache.bcel.classfile.JavaClass
Represents a Java class, i.e., the data structures, constant pool, fields, methods and commands contained in a Java .class file. See JVM specification for details. The intent of this class is to represent a parsed or otherwise existing class file. Those interested in programatically generating classes should see the ClassGen class.
