java - Refactoring Code Between Projects Results in RuntimeException: Uncompilable Code -

-

when copied on gui classes project new one, thought easy. unfortunately, wasn't. made game named entwine, who's package name net.jibini.entwine , new project's package name net.jibini.pilgrim. when attempt run refactored code (taken entwine , put pilgrim), error: java.lang.runtimeexception: uncompilable source code - package net.jibini.entwine not exist. can not find link original classes, don't know coming from.

this base gui class:

package net.jibini.pilgrim.gui;  /**  *  * @author zgoethel12  */ public abstract class gui {      public abstract void render();  }

this guipause class:

package net.jibini.pilgrim.gui;  import net.jibini.pilgrim.main; import org.lwjgl.opengl.display;  /**  *  * @author zgoethel12  */  import static org.lwjgl.opengl.gl11.*;  public class guipause extends gui {      guielementbutton back, quit;      public guipause() {         controls();     }      @override     public void render() {          glpushmatrix();         gltranslatef(0, 0, 10);          glbegin(gl_quads);         glvertex2f(10, display.getheight() - 10);         glvertex2f(440, display.getheight() - 10);         glvertex2f(440, 10);         glvertex2f(10, 10);         glend();          if (display.wasresized()) {             controls();         }          gltranslatef(0, 0, 1);          back.render();         quit.render();          glpopmatrix();      }      public void controls() {          = new guielementbutton(20, 20, 400, "back");         quit = new guielementbutton(20, display.getheight() - (back.height + 20), 400, "quit");          back.onclick = new onclicklistener() {             @override             public void onclick() {                 main.instance.gui = null;             }         };         quit.onclick = new onclicklistener() {             @override             public void onclick() {                 main.instance.exitgame();                 main.instance.gui = new guimainmenu();             }         };      }  }

and lastly, how set gui in game:

if (pressedi.contains(keyboard.key_escape)) {     if (gui == null) {         try {             gui = new guimainmenu();         } catch (exceptionininitializererror err) {             system.out.println(err.getcause());         }     } else {         gui = null;     } }

since happens every gui try show, think may problem base gui class or call controls(); in constructor. know problem , how fix , appreciate help!

regards, john smith

the solution problem go "project properties > compiling" , disable "compile on save"

i need hash algorithm produces 64-bit hash code ( long ) fewer collisions string.gethashcode() , fast (no expensive calls cryptographic functions). here's implementation of fnv still shows 3% of collisions after testing 2 million random strings. need number way lower. void main() { const string chars = "abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz!#@$%^&*()_+}{\":?><,./;'[]0123456789\\"; const int n = 2000000; var random = new random(); var hashes = new hashset<long>(); int collisions = 0; for(int = 0; < n; i++) { var len = random.next(chars.length); var str = new char[len]; (int j = 0; j < len; j++) { str[j] = chars[random.next(chars.length)]; } var s = new string(str); if(!hashes.add(get64bithash( s ))) collisions++; } console.writeline("collision percentage after " + n + " random strings: " + ((doubl
