The Method Area in JVM architecture stores type information, constant pool, field information, method table, method information, and class variables. It contains data about classes and interfaces such as fully qualified names, superclasses, interfaces, modifiers, constants, and references to fields and methods. The method table holds references to method information, while class variables store static and class variables.
