Java SE 7 is binary-compatible with Java SE 6 except for the incompatibilities listed below. Except for the noted incompatibilities, class files built with the Java SE 6 compiler will run correctly in Java SE 7. Any tool that modifies bytecode in a version 51 classfile must be sure to update the stackmap information to be consistent with the bytecode in order to pass verification. This list includes some of the notable RFEs that relate to JDK 7, Oracle’s implementation of Java SE 7. Changes to JDK 7 includes changes to javac, to HotSpot (and related tools), and to the implementation of the Java SE 7 API.

In addition to the language changes, other changes have been made to the Java Class Library over the years, which has grown from a few hundred classes in JDK 1.0 to over three thousand in J2SE 5. Entire new APIs, such as Swing and Java2D, have been introduced, and many of the original JDK 1.0 classes and methods have been deprecated. Some programs allow conversion of Java programs from one version of the Java platform to an older one (for example Java 5.0 backported to 1.4) (see Java backporting tools). Java SE 7 is strongly compatible with previous versions of the Java platform. Almost all existing programs should run on Java SE 7 without modification.

After Installing the JDK and JRE adds the java command to your command line. You can verify this through the command java se 7 tutorials prompt by the java -version command. In some cases, you need to restart your system after installing the JDK.

Applications will encounter the above exception if the size of the XSL template is too large. Alternatively, applications can override the JDK XSLT Transformer by providing third-party implementation JAR files in the class path. GraalVM for JDK 21 will receive updates under the GFTC, until September 2026, a year after the release of the next LTS. JDK 21 will receive updates under the NFTC, until September 2026, a year after the release of the next LTS. Subsequent JDK 21 updates will be licensed under the Java SE OTN License (OTN) and production use beyond the limited free grants of the OTN license will require a fee.
