1.Java class file is compiled, there will be a class constant pool
2. During class loading, the class constant pool is loaded into the runtime constant pool
so does this runtime pool have one for each class, or does all classes share one?
in JAVA8, is this runtime constant pool in the heap area or in metaspace?
what is the relationship between the runtime constant pool and the global string constant pool, and where is the global string constant pool?
String constant pool location:
I suggest you take a look at the Java8 Virtual Machine Specification, which has the answers you need. There is an electronic version of books
the runtime constant pool stores all kinds of literals and symbolic references (as the run changes the symbolic references used into direct references), each class has one, not a shared
string constant pool is a StringTable (which can be understood as weak HashMap), a String reference is stored, and the globally shared
these two pools are not the same thing at all!

Why does JAVA have multiple loaders I know that the function of the loader is to get the binary byte stream through the class name. It is mainly divided into four kinds of loaders: startup class-> extension class-> application class-> custom class. I al...
