Is the value of Integer.MAX_VALUE different between 32bit JVMs and 64bit JVMs?
I am compiling a Java class using 32bit JDK and deploy it on a 64bit machine. I just want to make sure that I can rely on detecting if (aNumber == Integer.MAX_VALUE).

In a 64-bit JVM, you can specify more memory for heap size than in a 32-bit JVM; for example, in a 32-bit JVM, the theoretical maximum memory limit is 4GB, whereas 64-bit is much higher.
Java with 64 and/or 32 bit web browsersUsers that run Applets and Web Start applications through web browsers should choose the version of Java that matches their web browser. Generally speaking, 64 bit browsers run only 64 bit plugins and 32 bit browsers run only 32 bit plugins.
MAX_VALUE is a number in the Java Integer сlass of java. lang package. It is the maximum possible Integer number that can be represented in 32 bits. Its exact value is 2147483647 i.e. 231-1.
No. By definition Integer.MAX_VAlUE = 2^31 - 1
Integer.MAX_VALUE

No. The 32-bit JDK makes 32-bit addresses for the instances, and the 64-bit JDK makes 64-bit addresses for the object instances. Thus, Integer.MAX_VALUE is the same, because it's just an value, not an object address. :)

This constant has the same value regardless of whether the JVM the code is running on is 32-bit or 64-bit. The documentation for Integer.MAX_VALUE describes this value as:
A constant holding the maximum value an
intcan have, 231-1.
