JTable与数据库 问题
public void out(){
String sql = "select * from admin";
db.dbconn();
int i=0,j;
try{
rs = db.stmt.executeQuery(sql);
ResultSetMetaData mm = rs.getMetaData();
while(rs.next()){
for(j=0;j<mm.getColumnCount();j++){
jTable.setValueAt(rs.getObject(j),i,j);
}
i = i + 1;
}
rs.close();
}catch(SQLException e){e.printStackTrace();}
db.closedb();

}

请问问题出在哪呢

------解决方案--------------------
jTable.setValueAt(rs.getObject(j),i,j); -> jTable.setValueAt(rs.getObject(j+1),i,j); // 数据是从1开始的，跟数组有点区别
