You can do smth like:

String StrRead() {
    byte[] enter = new byte[256];
    int num = 0;
    String str = new String();
    try {    
        num = System.in.read(enter);
    }
    catch (Exception e)
    {
        System.out.println(e.toString());
    }
    str = new String(enter,0,num);
    return str.trim();
}

and then just call String s = StrRead();
