将byte []转换为ArrayList <String>

Question

我在SO上找到了一个问题:将ArrayList <String>转换为byte []

它是关于转换ArrayList<String>为byte[].

现在可以转换byte[]成ArrayList<String>？

看起来没有人读原来的问题:)

如果您使用第一个答案中的方法分别序列化每个字符串,则完全相反的操作将产生所需的结果:

    ByteArrayInputStream bais = new ByteArrayInputStream(byte[] yourData);
    ObjectInputStream ois = new ObjectInputStream(bais);
    ArrayList<String> al = new ArrayList<String>();
    try {
        Object obj = null;

        while ((obj = ois.readObject()) != null) {
            al.add((String) obj);
        }
    } catch (EOFException ex) { //This exception will be caught when EOF is reached
        System.out.println("End of file reached.");
    } catch (ClassNotFoundException ex) {
        ex.printStackTrace();
    } catch (FileNotFoundException ex) {
        ex.printStackTrace();
    } catch (IOException ex) {
        ex.printStackTrace();
    } finally {
        //Close the ObjectInputStream
        try {
            if (ois != null) {
                ois.close();
            }
        } catch (IOException ex) {
            ex.printStackTrace();
        }
    }
}

如果你的byte []包含ArrayList本身,你可以这样做:

    ByteArrayInputStream bais = new ByteArrayInputStream(byte[] yourData);
    ObjectInputStream ois = new ObjectInputStream(bais);
    try {
        ArrayList<String> arrayList = ( ArrayList<String>) ois.readObject();
        ois.close();
    } catch (EOFException ex) { //This exception will be caught when EOF is reached
        System.out.println("End of file reached.");
    } catch (ClassNotFoundException ex) {
        ex.printStackTrace();
    } catch (FileNotFoundException ex) {
        ex.printStackTrace();
    } catch (IOException ex) {
        ex.printStackTrace();
    } finally {
        //Close the ObjectInputStream
        try {
            if (ois!= null) {
                ois.close();
            }
        } catch (IOException ex) {
            ex.printStackTrace();
        }
    }
}

这样的事情应该足够了,原谅任何编译错字我刚刚在这里喋喋不休:

for(int i = 0; i < allbytes.length; i++)
{
    String str = new String(allbytes[i]);
    myarraylist.add(str);
}
