JAVA操作字符集

mysql4.1.2的默认字符集是latin1，latin1属于ISO8859-1的子集(或者是一回事？)，写入时需要为iso8859-1的编码，读出时要转换成gbk编码，就不会是乱码。 Class.forName("org.gjt.mm.mysql.Driver");  String url ="jdbc:mysql://localhost/mysql";  Connection conn=DriverManager.getConnection(url,"root","root");    Statement stmt=conn.createStatement();  String a="老哈斯蒂芬";  a=new String(a.getBytes("GBK"),"iso8859-1");  stmt.executeUpdate("insert into zquan (name) value ('"+a+"')");      ResultSet rs=stmt.executeQuery("select name from zquan");  while(rs.next()){    String aaa=rs.getString(1);    System.out.println(new String(aaa.getBytes("iso8859-1"),"GB2312"));  }
