Hello all, I'm compiling a little program and receiving the following error. Error occurred during initialization of VM Could not reserve enough space for object heap I assume that VM stands for Virtual Machine, but not too sure about object heap. Any ideas??
Probably refers to the portion of memory allocated to a process in which objects "reside" at runtime. If you read about the String class, you will run across the term "string pool" and "heap" as in:
Bartenders and Sheriffs, do I understand it right? J. Lacar
sp is in the Constant Pool (which is usually in ROM). a new String containing "bar" is created on the heap (in RAM: Brodie this is what your problem is - just not enough of it) However ss is not an object. It is a variable that is holding an object. Variables get created in the stack (which is also in RAM)
Me again, I rebooted and now I'm receiving a new error. Even for my HelloWorld script, which was running properly, I'm receiving this error. I can compile the programs, but when I run them I receive the error: Error occurred during initialization of VM java/lang/NoClassDefFoundError: java/lang/Ojbect I installed Opera with the Java package bundled with it. I'm wondering if this is part of the problem.
What kind of computer and what platform are you working on? Your JRE may be too beefy for your hardware. Or ... the Java package that came with Opera may be fluff. You should go to java.sun.com/products and download a new JDK or JRE. Hope this helps ------------------ Chris Stehno (Sun Certified Programmer for the Java 2 Platform)
If the Opera app reconfigured your path and classpath, you might get such and error. Check them out and either put them back the way you want them or do your testing from the opera directories.
The J2SE API is a JavaDoc document providing information about all of the classes that come with the J2SE JVM. You use it to look up what methods are available in each class and how you can structure the constructor when creating an instance of each class etc. Unfortunately most of us mortals can not memorize the entire API, so we keep a reference to it handy at all times. There is an API document for each of the specialty areas also. There is an API doc for the 3D package that you can add on to the basic java classes, and another for Java Security, etc. Mostly I just keep a link to the plain API in my favorites and run off to read parts of it on a daily basis.
