In addition to language changes, significant 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 5.0. Entire new APIs, such as Swing and Java 2D, have evolved, and many of the original JDK 1.0 classes and methods have been deprecated (thereof some "terminally deprecated"), e.g. related to finalization.cite-ref-74[74]

At least one very rarely-used API (for threading) has been removed from Java 22.cite-ref-75[75]cite-ref-76[76]

Current Java is supported on 64-bit Windows 10 (and Server 2016) and later, 64-bit macOS 13.x and later, and 64-bit Linux (e.g. Oracle Enterprise Linux). Others are not supported by Oracle (for building, but may be by IBM, SAP etc.), though are known to work e.g. AIX, Ubuntu, RHEL, and Alphine/musl. 32-bit Windows support is deprecated since Java 22 (and 32-bit JVM no longer builds without non-default options).
