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 ...
A compiled Java program can run on a 32- or 64-bit Java virtual machine with no modification. The lengths and precision of all the built-in types, such as char, short, int, long, float, and double, and the types that can be used as array indices, are specified by the standard and are not dependent on the underlying architecture. Java programs ...
The Java language has undergone several changes since JDK 1.0 as well as numerous additions of classes and packages to the standard library.Since J2SE 1.4, the evolution of the Java language has been governed by the Java Community Process (JCP), which uses Java Specification Requests (JSRs) to propose and specify additions and changes to the Java platform.
Consequently, you can install a 32-bit or 64-bit JVM on a 64-bit operating system. The primary advantage of running Java in a 64-bit environment is the larger address space. This allows for a much larger Java heap size and an increased maximum number of Java Threads, which is needed for certain kinds of large applications; however there is a ...

Notable extensions include the .NET PE format for managed code, PE32+ for 64-bit address space support, and a specialized version for Windows CE. To determine whether a PE file is intended for 32-bit or 64-bit architectures, one can examine the Machine field in the IMAGE_FILE_HEADER. [6]
Tiered compiling, an option introduced in Java 7, uses both the client and server compilers in tandem to provide faster startup time than the server compiler, but similar or better peak performance. [9] Starting in Java 8, tiered compilation is the default for the server VM. [10] HotSpot is written in C++ and Assembly.
