How to read a Delimited Text file in Java?

We have following SEQ file from SFTP:

TSID ,D4 ; TEST ID # (PRIMARY)
TSNAME,A15 ; TEST NAME COMMON (ALTERNATE)
TSRNAM ,A15 ; PORT NAME
TSRELO ,A5 ; TEST REPEAT LOW VALUE
TSREHI ,A5 ; TEST REPEAT HIGH VALUE
TSSSRQ ,D2 ; SAMPLE SIZE REQ.
TSCTYP ,D2 ; CONTAINER TYPE
TSSUOM,A6 ; SAMPLE UNIT OF MEAS
TSINDX ,D4 ; WIDE REPORTING INDEX (ALTERNATE)
TSWKLF ,D2 ; WORKLIST FORMAT
TSMCCD,A8 ; MEDICARE CODE + MODIFIER 1 (ALTERNATE)
TSTADY ,D3 ; RESULT TURN-AROUND TIME IN DAYS
TSENOR ,A1 ; TEST HAS EXPANDED NORMALS Y/N
TSSRPT ,A1 ; ELIGIBLE FOR STATE NOTIFICATION REPORT Y/N
TSPLAB ,D2 ; SENDOUT LAB

The content of file are simple text like:

0001MONTH COMPOSITE                                     12319909110940                                                                                                                                MONTH COMPOSITE

Is there any Java Internal package (or Third party Java library) available to read file Delimited file (.SEQ) in such a way to assign each value to POJO directly using some sort of converters?

For ex:

public class ra(){
  @SomethigLength (0,4)
  private String tsId;
  @SomethigLength (4,15)
  private String tsName;
}

(Note we are using Apache Camel here but i think camel may be complicated compare to any simple library?)

Solution

You can use camel-bindy with Fixed-Length records(https://camel.apache.org/components/latest/bindy-dataformat.html#_4_fixedlengthrecord)

So your class will be like:

    @FixedLengthRecord(length = 15, paddingChar = ' ')
    public class Fastbox {

        @DataField(pos = 1, length = 4, align = "L")
        private String tsId; 

        @DataField(pos = 2, length = 11, align = "L")
        private String tsName; 
    }

and with unmarshal() you can convert the file to Java object.
