java中创建文件的方法之间的区别

import java.io.ByteArrayInputStream;
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;

public class Modify {

    public static void main(String[] args) throws IOException {
        String path = "F:\Users\yyy\Desktop\111.docx";
        Modify modify = new Modify();
        modify.create("hhh",path);
    }

    /**
     *
     * @param inputString 需写入的字符串内容
     * @param path 文件创建的路径
     * @throws IOException
     */
    private void create(String inputString,String path) throws IOException {
        String newPath = path.substring(0,path.lastIndexOf("\"));
        File file = new File(newPath);
        if (!file.exists()){
            file.mkdirs();
        }
        File newFile = new File(path);
        if (!newFile.exists()){
            newFile.createNewFile();
        }
        ByteArrayInputStream input = new ByteArrayInputStream(inputString.getBytes());
        int index;
        byte[] bytes = new byte[1024];
        FileOutputStream fs = new FileOutputStream(path);
        while ((index = input.read(bytes)) != -1) {
