    copied!<p>I am doing a game in J2ME . I want save data level and score in RMS .This is my code This is class RMSData :</p> <pre><code>public class RMSData { private static RecordStore rs = null; static final String REC_STORE = "ReadWriteRMS"; public static void openRecStore(){ try { rs = RecordStore.openRecordStore(REC_STORE, true); } catch (Exception e) {} } public static void closeRecStore(){ try { rs.closeRecordStore(); } catch (Exception e) {} } public static void deleteRecStore(){ if(RecordStore.listRecordStores()!= null){ try { RecordStore.deleteRecordStore(REC_STORE); } catch (Exception e) {} } } public static void writeRecStore(String str){ byte[] rec = str.getBytes(); try { rs.addRecord(rec, 0, rec.length); } catch (Exception e) {} } public static String readRecStore(){ String kq =null; try{ byte[] recData = new byte[5]; int len; if (rs.getNumRecords()==0) return null; for(int i = 1; i &lt;= rs.getNumRecords(); i++){ if(rs.getRecordSize(i) &gt; recData.length){ recData = new byte[rs.getRecordSize(i)]; } len = rs.getRecord(i, recData, 0); if (i==rs.getNumRecords()) kq = new String(recData, 0, len); } }catch (Exception e){} return kq; } } </code></pre> <p>I write level and score to RMS :</p> <pre><code>RMSData.openRecStore(); RMSData.writeRecStore(String.valueOf(LevelPlay)); RMSData.writeRecStore(String.valueOf(Score)); RMSData.closeRecStore(); </code></pre> <p>And then I read it :</p> <pre><code>RMSData.openRecStore(); String st = null; if(RMSData.readRecStore() == null) st = "Level : 0"+"Score : 0"; else st = "Level : "+RMSData.readRecStore()+"Score : "+RMSData.readRecStore(); RMSData.closeRecStore(); </code></pre> <p>But it can't read the data.</p>
