Javaでのファイル作成方法の違い

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

public class Modify {

        String path = "F:\\Users\\yyy\\Desktop\\111.docx";
        Modify modify = new Modify();

    }

     *
     * @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);
