Question

这可能是一个愚蠢的问题，但我想将2维字符串数组转换为java中的可序列化对象。这样做的最佳方式是什么？

Answer 1

数组已经是Serializable。 String也是如此。你不需要任何其他的东西。

这是一个完整的例子：

import java.io.*;
import java.util.Arrays;

/**

public class Serial {

    public static void main(String[] args)
            throws IOException, ClassNotFoundException {
        PipedOutputStream pos = new PipedOutputStream();
        PipedInputStream pis = new PipedInputStream(pos);

        String[][] strings = new String[][]{{"q","w","e"},{"a","s","d"},{"z",
                "x","c"}};

        serialize(strings, pos);

        String[][] strings2 = deserialize(pis);

        System.out.println(Arrays.deepEquals(strings, strings2));
    }

    public static String[][] deserialize(InputStream is)
            throws IOException, ClassNotFoundException {
        ObjectInputStream ois = new ObjectInputStream(is);
        return (String[][]) ois.readObject();
    }

    public static void serialize(String[][] array, OutputStream os)
            throws IOException {
        ObjectOutputStream oos = new ObjectOutputStream(os);

        oos.writeObject(array);
        oos.flush();
    }
}

        ObjectOutputStream stream = null;
    try {
        stream = new ObjectOutputStream(out);
        String strings[][] = {
                {"a", "b", "c"},
                {"1", "2", "3"},
        };
        stream.writeObject(strings);
    } catch (IOException e) {
        e.printStackTrace();  //$REVIEW$ To change body of catch statement use File | Settings | File Templates.
    }

这就是答案。默认情况下，数组是可序列化的。只需将其写入ObjectOutputStream，就像另一个可序列化对象

一样

转换为Serializable对象
