I am trying to create a GUI in Java, but this error keeps popping up and I do not know what to do to fix this error. Any help would be appreciated with fixed java code

$//$ Arrays to store data

public int$[]$ itemCode;

public String$[]$ itemName;

public float$[]$ unitPrice;

$//$ Item constructor

HW$4()\{//$ Reading file$//$ Getting dataitemName $=$ new String$[$data$.$length$]$;for $($int i $=0$; i $$ data.length; i$++)\{$ itemCode$[$i$]=$ Integer.parseInt$($dataDivided$[0])$; unitPrice$[$i$]=$ Float.parseFloat$($dataDivided$[2])$;$\}$

$//$ Reading files from the source provided

public String$[]$ readFile$($String$[]$ records$)\{$ String line; while $(($line $=$ br$.$readLine$())!=$ null$)\{$ recordsList.add$($String$.$join$(",",$ values$))$; return recordsList.toArray$($new String$[0])$; e$.$printStackTrace$()$;return records;

$\}$

$//$ GetName function

public String getName$($int code$)\{\}$

$//$ GetPrice function

public double getPrice$($int code$)\{\}$
