java - Knuth Morris Pratt application no error but not working -

here's application

"textform", take value searchbox.

"listkamus", take value array. "player name", change value string.

"kmp.knutmorris(textform, playername)", send textform, playername value knutmorris class

main class

public void ontextchanged(charsequence s, int arg1, int arg2, int arg3) {     string textform = s.tostring();     searchresults.clear();      for(int i=0;i<listkamus.size();i++)        {       string playername=listkamus.get(i).tostring();       kmp.knutmorris(textform, playername);         if(kmp.value==1){         searchresults.add(listkamus.get(i));         }         }     adapter.notifydatasetchanged(); } 

kmp class

public class kmp {  /** failure array **/  private int[] failure; public static int value;  /** constructor **/  public kmp(string text, string pat)  {  /** pre construct failure array pattern **/  failure = new int[pat.length()];  fail(pat);  /** find match **/  int pos = posmatch(text, pat);  if (pos >= 0) { kmp.value = 1; } }  /** failure function pattern **/  private void fail(string pat)  {  int n = pat.length();  failure[0] = -1;  (int j = 1; j < n; j++)  {      int = failure[j - 1];      while ((pat.charat(j) != pat.charat(i + 1)) && >= 0)          = failure[i];      if (pat.charat(j) == pat.charat(i + 1))          failure[j] = + 1;      else          failure[j] = -1;  }  }  /** function find match pattern **/  private int posmatch(string text, string pat)  {  int = 0, j = 0;  int lens = text.length();  int lenp = pat.length();  while (i < lens && j < lenp)  {      if (text.charat(i) == pat.charat(j))      {          i++;          j++;      }      else if (j == 0)          i++;      else          j = failure[j - 1] + 1;  }  return ((j == lenp) ?

i want when people type on searchbox shows right list of array.

i think error 1 here

main class

 if(kmp.value==1){         searchresults.add(listkamus.get(i));         } 

or here

kmp class

if (pos >= 0) { kmp.value = 1; } 

can tell me how fix ?
