MySQL not executing (Java)

For some reason I'm not able to update my database using this code. Can someone help me out? What I've got is when a player completes a certain task it records the time it took them if and only if their time is lower than the best recorded time.

    public void setScores(MapleCharacter chr, int mapid, float time) {
    Connection con1 = DatabaseConnection.getConnection();
    try {
        PreparedStatement ps;
        ps = con1.prepareStatement("SELECT time from jumpquests WHERE characterid = ? AND mapid = ?");
        ps.setInt(1, chr.getId());
        ps.setInt(2, chr.getMapId());
        ResultSet rs = ps.executeQuery();
        if (rs.next()) {
            if (time < rs.getFloat("time")) {
                executeScores(chr, mapid, time);
            }
        } else {
            executeScores(chr, mapid, time);
        }
        rs.close();
        ps.close();
    } catch (Exception Ex) {
        System.out.println("Ran into exception.");
    }
}

public void executeScores(MapleCharacter chr, int mapid, float time) {
    System.out.println("Setting scores for " + chr.getName() + " for map " + mapid + " at time " + time);
    Connection con1 = DatabaseConnection.getConnection();
    try {
        PreparedStatement ps = con1.prepareStatement("REPLACE INTO jumpquests (characterid, mapid, time) values (?,?,?)");
        ps.setInt(1, chr.getId());
        ps.setInt(2, chr.getMapId());
        ps.setFloat(3, time);
        ps.close();
    } catch (Exception e) {
        System.out.println("Executing scores ran into exception.");
    }
}
