更多信息和选项

  • To use JavaBlock, you first need to load J/Link using Needs["JLink`"].
  • JavaBlock is a way to mark a set of objects as temporary so they can be automatically cleaned up when the block of code ends.
  • JavaBlock affects only new objects, not additional references to ones that have previously been seen.
  • If a JavaBlock returns a single JavaObject as a result, that object will not be released.
