Did you ever wonder when a particular class was introduced into the JDK? Or did you ever want to get a quick overview of all new classes included in a new release of Java? That is why I maintain my personal list of all public classes together with the JRE's version they were introduced. I started the list in 2002 and have been updating it whenever a new version of Java came out. Now, almost two years after the release of Tiger, it is high time to update my list with Java 5.Source of Truth
There is only one true source of the contents of a JRE, and that is
rt.jar. Getting a plain list of all *.class files inside the archive is not enough because some classes are package accessible and cannot be used in Java code directly. I use a series of shell scripts that generate a text file with all Java classes of rt.jar. After unpacking rt.jar a script iterates all class names and calls javap -public %class% >> access.log for each of them. Stripping all public content from access.log reveals the package accessible classes, e.g. java.awt.MutableBoolean java.beans.ReflectionUtils java.util.JumboEnumSet java.util.XMLUtils ...The list of new classes is the list of all classes found in
rt.jar minus the package accessible classes, minus all classes of all earlier versions of Java.Java 5
Tiger adds 172 new public types in the
java. name-space. The new classes arejava.awt.datatransfer.FlavorEvent java.awt.datatransfer.FlavorListener java.awt.MouseInfo java.awt.peer.KeyboardFocusManagerPeer java.awt.peer.MouseInfoPeer java.awt.PointerInfo java.beans.IndexedPropertyChangeEvent java.io.Closeable java.io.Flushable java.lang.Appendable java.lang.Deprecated java.lang.Enum java.lang.EnumConstantNotPresentException java.lang.Iterable java.lang.Override java.lang.ProcessBuilder java.lang.Readable java.lang.reflect.AnnotatedElement java.lang.reflect.GenericArrayType java.lang.reflect.GenericDeclaration java.lang.reflect.GenericSignatureFormatError java.lang.reflect.MalformedParameterizedTypeException java.lang.reflect.ParameterizedType java.lang.reflect.Type java.lang.reflect.TypeVariable java.lang.reflect.WildcardType java.lang.StringBuilder java.lang.SuppressWarnings java.lang.TypeNotPresentException java.math.MathContext java.math.RoundingMode java.net.CacheRequest java.net.CacheResponse java.net.CookieHandler java.net.HttpRetryException java.net.Proxy java.net.ProxySelector java.net.ResponseCache java.net.SecureCacheResponse java.rmi.server.RemoteObjectInvocationHandler java.security.AuthProvider java.security.CodeSigner java.security.interfaces.ECKey java.security.interfaces.ECPrivateKey java.security.interfaces.ECPublicKey java.security.KeyRep java.security.spec.ECField java.security.spec.ECFieldF2m java.security.spec.ECFieldFp java.security.spec.ECGenParameterSpec java.security.spec.ECParameterSpec java.security.spec.ECPoint java.security.spec.ECPrivateKeySpec java.security.spec.ECPublicKeySpec java.security.spec.EllipticCurve java.security.spec.MGF1ParameterSpec java.security.Timestamp java.security.UnrecoverableEntryException java.util.AbstractQueue java.util.DuplicateFormatFlagsException java.util.EnumMap java.util.EnumSet java.util.FormatFlagsConversionMismatchException java.util.Formattable java.util.FormattableFlags java.util.Formatter java.util.FormatterClosedException java.util.IllegalFormatCodePointException java.util.IllegalFormatConversionException java.util.IllegalFormatException java.util.IllegalFormatFlagsException java.util.IllegalFormatPrecisionException java.util.IllegalFormatWidthException java.util.InputMismatchException java.util.InvalidPropertiesFormatException java.util.jar.Pack200 java.util.logging.LoggingMXBean java.util.MissingFormatArgumentException java.util.MissingFormatWidthException java.util.PriorityQueue java.util.Queue java.util.regex.MatchResult java.util.Scanner java.util.UnknownFormatConversionException java.util.UnknownFormatFlagsException java.util.UUIDas well as 86 classes of the four completely new packages
java.lang.annotation java.lang.instrument java.lang.management java.util.concurrentFurther there are around 300 new types in
javax. packages. The JMX Management Extension 1.2, javax.management, adds more than 170 classes and is a major addition. Further there are several smaller new packages, mainlyjavax.jnlp javax.sql.rowset javax.xml.datatype javax.xml.namespace javax.xml.validation javax.xml.xpathi.e. JNLP-Client 1.0 for JavaWebStart, SQL RowSet implementations and several XML functions from JAXP 1.3 like schema mapping, name-spaces, schema validation and XPath.
Full Class List
Here is the complete list of all classes from Java 1.0 to 1.5, to be more precise from Sun's JDK 1.02 and 1.1.8_09, J2SE 1.2.2_13, 1.3.1_08 and 1.4.2_03, and the new Java5 1.5.0_07. This list gets more and more valuable because it becomes more and more difficult to get older JDKs.
