java manipulating local files

1. Write a local file

/**
 *
 * @param sDestFile filename
 * @param sContent content
 *  autho whh
 */
    public static void appendToFile(String sDestFile, String sContent) {
    // String sContent = "I love Ysm";
    // String sDestFile = "F:/work/logParse/autoCreateHql/myWrite.txt";
    File destFile = new File(sDestFile);
    BufferedWriter out = null;
    if (!destFile.exists()) {
        try {
            destFile.createNewFile();
        } catch (IOException e) {
            e.printStackTrace ();
        }
    }
    try {
        out = new BufferedWriter(new OutputStreamWriter(new FileOutputStream(sDestFile, true)));
        out.write(sContent);
        out.newLine();
    } catch (Exception e) {
        e.printStackTrace ();
    } finally {
        try {
            if (out != null) {
                out.close();
            }
        } catch (IOException e) {
            e.printStackTrace ();
        }
    }
}

2. Find all files with file names ending with a certain string

public static void findFile(File file) {
//1. First determine whether the incoming path exists
        if (file.exists()) {

            // 2. If it is a file, determine whether it ends with java

            if (file.isFile()) {
                String filePath = file.getPath();
                if (file.getPath().endsWith("createtable.sh")) { //limited to end with "createtable.sh"
                    appendToFile("G:\\work\\compareHiveMetaToTreasury\\createtableFileName",filePath);
                   // System.out.println(filePath);
                }
            }
            // 3 If the folder is given, it needs to be called recursively
            if (file.isDirectory()) {
                File[] otherFile = file.listFiles();
                for (File f : otherFile) {
                    findFile(f);// Called recursively
                }
            }
        } else {
            System.out.println("The folder you gave does not exist");
        }
    }
