I am writing a code which gives different colors to key works.
I have written following code which will compare with key word say "ABC" when ever it finds "ABC" it will make it into blue color else red color.I am not getting whats wrong in my code.

private void jTextPane1KeyPressed(java.awt.event.KeyEvent evt) {                                      
        StyledDocument d = jTextPane1.getStyledDocument();
        MutableAttributeSet a = new SimpleAttributeSet();
    String sr,sr1;
    sr=jTextPane1.getText();
    int i,j,k=0,l,len=0;
    l=0;
    i=sr.length();
    while(k<jTextPane1.getText().length())
    {
        if(jTextPane1.getText().charAt(k)==' ')
        {
           len++;
        }
        k++;
    }
    do
    {
       j=sr.lastIndexOf(" ",i-1);
      if(j>=0)
      {
        k=j;
        sr1=sr.substring(j,i);
        if(sr1.compareToIgnoreCase("ABC")==0){
            StyleConstants.setForeground(a, Color.blue);
            d.setCharacterAttributes(j, i+1, a, false);
        }
       else
       {
         StyleConstants.setForeground(a, Color.red);
         d.setCharacterAttributes(j, i, a, false);
       }
        i=j;
        l++;
      }
      else
      {
           if(sr.substring(0,i).compareToIgnoreCase("ABC")==0){
            StyleConstants.setForeground(a, Color.blue);
            d.setCharacterAttributes(0, i+1, a, false);
        }
        else
        {
            StyleConstants.setForeground(a, Color.red);
            d.setCharacterAttributes(0, i, a, false);
        } 
          l++;
      }
    }
    while(l <= len);
}
