Cant resolve syntax error.

Question

In the current program I am trying to read multiple text files from a folder. I keep getting the following syntax error
"Syntax error on token ";", { expected after this token". I highlighted the line where im getting this error in red.
import java.io.*;
import java.util.*;
public class CacheData {
  // Directory path here
    String path = "C:\\myfiles\\*.txt";
    String files;
    File folder = new File(path);
    File[] listOfFiles = folder.listFiles();
    for (int i = 0; i < listOfFiles.length; i++)
        if (listOfFiles[i].isFile())
            files = listOfFiles[i].getName();
            if (files.endsWith(".txt") || files.endsWith(".TXT"))
                System.out.println(files);
                TreeMap<String, Integer> frequencyMap = new TreeMap<String, Integer>();
                String currentLine="";
                File textFile = new File(files);
                try {
                    BufferedReader br = new BufferedReader(new FileReader(textFile));
                    while ((currentLine = br.readLine()) != null) {
                        currentLine = currentLine.toLowerCase();
                        StringTokenizer parser = new StringTokenizer(currentLine, " \t\n\r\f.,;:!?'");
                        while (parser.hasMoreTokens()) {
                            String currentWord = parser.nextToken();
                            Integer frequency = frequencyMap.get(currentWord);
                            if (frequency == null) {
                                frequency = 0;
                            frequencyMap.put(currentWord, frequency + 1);
                    br.close();
                } catch (FileNotFoundException e) {
                } catch (IOException e) {
                    // TODO Auto-generated catch block

Code MUST BE in a method or static block.
Your code HAS NO METHODS.
I suggest you start by working with the many examples in the 'Reading, Writing, and Creating Files' trail of The Java Tutorials.
https://docs.oracle.com/javase/tutorial/essential/io/file.html
Then clone one of those examples and modify it for your own requirements.
