Java追加文件的三种方式

import java.io.BufferedWriter;
import java.io.File;
import java.io.FileOutputStream;

            randomFile.seek(fileLength);
            randomFile.writeBytes(content);
        } catch (IOException e) {
            e.printStackTrace();
        } finally{
            if(randomFile != null){
                try {
                    randomFile.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }
    }

    public static void main(String[] args) {
        try{
            File file = new File("d://text.txt");
            if(file.createNewFile()){
                System.out.println("Create file successed");
            }
            method1("d://text.txt", "123");
            method2("d://text.txt", "123");
            method3("d://text.txt", "123");
        }catch(Exception e){
            System.out.println(e);
        }
    }
