Java programming How do i change this program to scan data from file and find the sum of the valid entry and count vaild and invalid entries The provided data file contains entries in the form ABCDE BB That is $-$ a value ABCDE, followed by the base BB$.$ Process this file, convert each to decimal $($base $10)$ and determine the sum of the decimal $($base $10)$ values. Reject any entry that is invalid. Report the sum of the values of the valid entries and total number of invalid entries $//$data$.$txt file contains following as input $//$First word is number and second is base, desired base is always $10$; $//$ for example thVkFu$632$ thVkFu$6$ is the number that should be converted into base $10$ and $32$ is the current base of thVkFu$6.$ thVkFu$6326$b$416$C$1$bD$23$A $14$ Ie$7$E$0$CHjgfej $22$ DXBV$8$bON$6$L$3$KMoRM $342$KiomlR$4$t$0$T$7$IO$630712$d$6$Ab$8148231489531$b$759125813045482$d$0$b$110$ lJ$3939$oG$06256$EhE$85$I$73$Da$52$fb $19$ aE$1$GfIi$42$D$1$ck$1$GgC$9$H $214$Lg$9$e$34$b$9$j $22$ ebA $1564$KJdan$8$n$052725$F$48$ccC$4$bCI$2$Jg$91$D$482064$dCf$51810111010021135$ aD$5$X$5772114$ a$41511105$ F$5$V $3231$LpjOb$73487216601747410738//$This is my program import java.math.BigInteger; import java.util.ArrayList; import java.util.List; import java.util.Scanner; public class BaseConversion $\{$ public static boolean isValidInteger$($String number, int base$)\{$ List $<$ Character $>$ occc $=$ new ArrayList $<$ Character $>()$; for $($int i $=0$; i $<10$ && i $<$ base; i$++)\{$ occc.add$(($char$)(\text{'}0\text{'}+$ i$))$; $\}$ if $($base $>=10)\{$ for $($int i $=0$; i $<=$ base $-10$; i$++)\{$ occc.add$(($char$)(\text{'}$A$\text{'}+$ i$))$; $\}\}$ for $($char c: number.toCharArray$())\{$ if $(!$occc.contains$($c$))\{$ return false; $\}\}$ return true; $\}$ private static int charValueInDecimal$($char c$)\{$ if $($c $<=\text{'}9\text{'}$ && c $>=\text{'}0\text{'})\{$ return c $-\text{'}0\text{'}$; $\}$ return c $-\text{'}$A$\text{'}+10$; $\}$ private static char digitInChar$($int c$)\{$ if $($c $<=9$ && c $>=0)\{$ return $($char$)($c $+\text{'}0\text{'})$; $\}$ return $($char$)(($c $-10)+\text{'}$A$\text{'})$; $\}$ public static String convertInteger$($String firstValue, int firstBase, int finalBase$)\{$ BigInteger num $=$ BigInteger.ZERO; for $($char c: firstValue.toCharArray$())\{$ BigInteger x $=$ num.multiply$($new BigInteger$($String$.$valueOf$($firstBase$)))$; num $=$ x$.$add$($new BigInteger$($String$.$valueOf$($charValueInDecimal$($c$))))$; $\}$ String result $=""$; BigInteger desired $=$ new BigInteger$($String$.$valueOf$($finalBase$))$; while $(!$num.equals$($BigInteger$.$ZERO$))\{$ BigInteger remain $=$ num.mod$($desired$)$; result $=$ digitInChar$($remain$.$intValue$())+$ result; num $=$ num.divide$($desired$)$; $\}$ return result; $\}$ public static void main$($String$[]$ args$)\{$ Scanner in $=$ new Scanner$($System$.$in$)$; System.out.println$("$Welcome to Base Conversion program!"$)$; System.out.println$("")$; System.out.println$("$Enter the value to be converted: $")$; String number $=$ in $.$nextLine$().$toUpperCase$()$; System.out.println$("$Enter the base of the entered value: $")$; int base $=$ Integer.parseInt$($ in $.$nextLine$())$; int desiredBase $=10$; $//$ Desired base is always $10$ if $(!$isValidInteger$($number$,$ base$))\{$ System.out.println$("$Invalid number entered for base $"+$ base$)$; $\}$ if $($base $<2||$ base $>36)\{$ System.out.println$("$Base value $"+$ base $+"$ Must be in $[2,36]")$; System.exit$(0)$; $\}\}$ System.out.println$("$Converting $"+$ number $+"$ from base $"+$ base $+"$ to base $"+$ desiredBase $+"...")$; System.out.println$("")$; System.out.println$($convertInteger$($number$,$ base, desiredBase$))$; in $.$close$()$; $\}\}$
