  • Method Details

    • max

      long max()
      Returns the maximum amount of memory in bytes that can be used for memory management. This method returns -1 if the maximum memory size is undefined.

      This amount of memory is not guaranteed to be available for memory management if it is greater than the amount of committed memory. The Java virtual machine may fail to allocate memory even if the amount of used memory does not exceed this maximum size.

      Returns:
      the maximum amount of memory in bytes; -1 if undefined.

    • committed

      long committed()

      Returns:
      the amount of committed memory in bytes.

    • used

      long used()
      Returns the amount of used memory in bytes.
