java - Custom "hash table" implementation: Why is it so slow? (bytecode generation) -

-
today, answered ordinary question of java beginner. little bit later thought fun take question , implemented wants. i created simple code runtime class generation. of code taken template, possible change declare fields. generated code written as: public class container implements storage { private int foo; // user defined (runtime generated) private object boo; // user defined (runtime generated) public container() { super(); } } the generated class file loaded jvm using custom classloader. then implemented "static hashtable". programmer enters possible keys , generates class (where each key field). in moment have instance of class, may save or read generated fields using reflection. here whole code: import java.io.bytearrayoutputstream; import java.io.ioexception; import java.util.arraylist; import java.util.hashtable; import java.util.random; class classgenerator extends classloader { private arraylist<fieldinfo> field

java - how can I find default attributes for JTextPane document? -

-
i'm working jtextpane. jtextpane pane = new jtextpane(); string content = "i'm line of text displayed in jtextpane"; styleddocument doc = pane.getstyleddocument(); simpleattributeset aset = new simpleattributeset(); if add aset textpane's document this: doc.setparagraphattributes(0, content.length(), aset, false); nothing visible happens. no big surprise since haven't set custom attributes aset . however, if allow aset replace current paragraphattributes of doc this: doc.setparagraphattributes(0, content.length(), aset, true); a lot of things happen. how can information on default values of jtextpane document? particularly problems when i'm defining custom font aset , set replace current attributes, font displayed if bold. styleconstants.setbold(aset, false); doesn't help. i have looked @ source code see data structures holding information want. modification of code prints attributes each paragraph. int offset, length;
