在学习 java 内存分析时，除了“堆”之外，我不断看到术语“永久空间”。我知道堆是什么——烫发空间是什么？
最佳答案
它代表permanent generation :
The permanent generation is special because it holds meta-data describing user classes (classes that are not part of the Java language). Examples of such meta-data are objects describing classes and methods and they are stored in the Permanent Generation. Applications with large code-base can quickly fill up this segment of the heap which will cause
java.lang.OutOfMemoryError: PermGen no matter how high your -Xmx and how much memory you have on the machine.
