> Usage:

> )
> .withSchema(
> schema

> {code}
>
> (1) RowTypeInfo(fieldsType,fieldNames) calls toString method:
> Row(name: String, age: Integer, sex: String, datatime:
> BasicArrayTypeInfo<String>)
> `datatime` field type is BasicArrayTypeInfo<String>.
>
> (2)Schema shema :
> schema = schema.field(fieldNames[i],fieldsType[i]);
> `datatime` field type is BasicArrayTypeInfo<String>
