Nit: I'd suggest to make get() an instance method. It will be a little bit
simpler and more natural.
It wiill look as below:
static void check(Class cls) throws Exception {
FieldExplorer explorer = new FieldExplorer(cls);
List<String> fields = explorer.get();
check(cls, fields.toArray(new String[0]));
}
. . .
List<String> get() throws Exception {
System.out.println("Class " + cls.getName());
try (InputStream classBytes = getClassBytes()) {
ClassReader classReader = new ClassReader(classBytes);
classReader.accept(this, 0);
}
return fieldNameAndSig;
}
