How to found a file by utilizing a variable for 'Startswith' in JAVA?

[MOHAMMAD ZAINUL ABIDEEN]

I'm trying to find a file based on the starting eight digits extracted from an excel sheet for every iteration. I am receiving the error notice "Local variable CaseID declared in an enclosing scope must be final or effectively final" so i am using the code below and still appears to be fresh, so I don't know how to correct this, Even after it happen to be a straightforward repair.

package Chrome;
//CHROME
import java.io.File;
import java.io.FileFilter;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.FilenameFilter;

import org.apache.poi.ss.usermodel.Cell;
import org.apache.poi.ss.usermodel.DataFormatter;
import org.apache.poi.xssf.usermodel.XSSFCell;
import org.apache.poi.xssf.usermodel.XSSFSheet;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;
import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.chrome.ChromeDriver;
import org.openqa.selenium.chrome.ChromeOptions;

public class ValidateInput {

public static void main(String[] args) throws Throwable {
// TODO Auto-generated method stub

// String filePath=System.getProperty("user.dir")+"\\UP.xlsx";
//File src = new File(filePath);
//System.out.println(filePath);
File src = new File("C:\\Users\\Z246379\\Documents\\TestDataFolder\\ValidateInput.xlsx");
FileInputStream fis = new FileInputStream(src);

XSSFWorkbook wb = new XSSFWorkbook(fis);
XSSFSheet Sheet1 = wb.getSheetAt(0);
int i1 = 2;
//Username
String data0 = Sheet1.getRow(2).getCell(0).getStringCellValue();
//Password
String data01 = Sheet1.getRow(2).getCell(1).getStringCellValue();
//Case ID
String caseID = Sheet1.getRow(i1).getCell(2).getStringCellValue();
// Description
String Desc = Sheet1.getRow(2).getCell(3).getStringCellValue();
//Internal Claim File
String ICF = Sheet1.getRow(1).getCell(4).getStringCellValue();
String CRPT = Sheet1.getRow(1).getCell(5).getStringCellValue();

// final String caseID1 = caseID1;

//Chrome driver code

System.out.println("Called openBrowser");
String exePath = System.getProperty("user.dir")+"\\chromedriver.exe";
System.setProperty("webdriver.chrome.driver", exePath);
ChromeOptions options = new ChromeOptions();
options.setExperimentalOption("useAutomationExtension", false);
options.addArguments("start-maximized");
options.addArguments("--no-sandbox");
options.addArguments("--disable-extensions-except");
options.addArguments("disable-extensions");
//options.setE

Try this:

final String caseId1 = caseID; // add this final variable
FilenameFilter filter = new FilenameFilter() {
public boolean accept (File dir, String name) {
return name.startsWith(caseId1); // use the final variable here
}
};
