Обеспечение 'int' размер 32 бита в Java после компиляции с 64 битным компилятором JAVAC и интерпретировать с использованием 64-битнойРазмер примитивного данных является частью virtual machine specification, и не меняется. Что изменит размер ссылок на объекты, от 32 бит...
To compare the performance of 64-bit WebSphere® to 31-bit WebSphere, an attempt was made to identify the optimal percentage of available memory to dedicate The correlation of response time with CPU utilization when scaling the Java™ heap size indicates that both have a common dependency. Misc 64-bit questions with java. Hi, 1) Using 64-bit allows an application to access a much larger space of virtual memory. It looks as if you cannot have more than 4gb as the heap size on a 64-bit machine, and 2gb on a 32-bit 2) The default for the 64-bit system is that int is 32 bits, long is 64 bits. See this page from Sun: http... What will be if java program is being shifted from 64 bit machine to 32... A Java program should run on any platform (hardware + operating system) for which a JVM (Java Virtual Machine) is installed. Unlike the "C" language, the size of data items in Java does not depend on the platform; for example, an int will always have a size of 32 bits, no matter how the underlying...
64 bit - 32-bit vs. 64-bit systems - Super User Sun's 64-bit Java virtual machines are slower to start up than their 32-bit virtual machines because Sun has only implemented the "server" JIT compiler (C2) for 64-bit platforms.[9] The "client" JIT compiler (C1), which produces less efficient code but compiles much faster, is unavailable on 64-bit platforms. Q&A: Java 32 and 64 on 64 bit machines? | ITNinja The weird thing is the only reason I even looked at the java control panel is because with this last push of 7v17, whoever had 6v31 installed would get a prompt in IE to make changes per 6v31, which never happned before and I thought it was because this past push I pused 32 java to 32 and 64 bit machines.

int on a 64-Bit machine Correct - in unmanaged C++ an int is 64 bit on a 64 bit machine with a 64 bit compiler. The only reason I can see you wanting 64 bits in a managed situation is if you were trying to access over the 4 GB addressable memory limit (for which there are collections such as BigArray), or if you were... Java Primitive Data Types. Size, Range and Default Value of Basic... *boolean represents one bit of information, but its "size" isn't something that's precisely defined. [Source: Sun's data type tutorial]. It is important to note that Java does not support unsigned types. All int variants are signed. But char is an exception; it is unsigned and consumes 2 bytes in memory. c++ Size of int and sizeof int pointer on a 64 bit machine? - Recalll
