Increase the java heap space for browser applets

A common problem for java programmers is the "java.lang.OutOfMemoryError: Java heap space" error. It means that your application uses too much memory. You can increase the amount of memory your applet is allowed to use on the command line. However you can also set it at the Java Control Panel.

Note that where I fill in -Xmx800m (800MB), you can also do -Xmx300m (300MB) and -Xmx1g (1GB) etc.

@SuperHobo1234567 Absolute bullshit. Good luck getting a stable clock with so much RAM. Assuming it would be supported by anything but servers, the timings would have to be too high to use it as a normal computer user. Please dont spread false information.

@picorettte Common sense. Know how much RAM your system uses, find out how much you actually have and then estimate how much RAM you want Java to take up without disturbing your usual computer usage.

HELP!

@R33TaRDationNaTIon 2 lines means you have 2 versions of Java installed, uninstall the lesser version.
