如何转换一个String数组字节数组？ （JAVA） [英] How to convert a String array to a Byte array? (java)

问题描述

我有我想转换成一维字节数组的一维字符串数组。我该怎么做呢？这是否需要ByteBuffer的？我怎样才能做到这一点？ （该字符串可以是任意长度，只是想知道如何去这样做，这种行为，而且可以将其转换为字节数组后，我怎么可能把它转换回一个String数组？

I have a one dimensional String array that I want to convert into a one dimensional byte array. How do I do this? Does this require ByteBuffer? How can I do this? (The strings can be any length, just want to know how to go about doing such an act. And after you convert it into a byte array how could I convert it back into a String array?

推荐答案

在阵列则应将手动与解析成两边，但是如果你刚刚字符串可以 String.getBytes（）和新的字符串（字节[]数据）;
像这样

Array to Array you should convert manually with parsing into both sides, but if you have just a String you can String.getBytes() and new String(byte[] data); like this

public static void main(String[] args) {
    String[] strings = new String[]{"first", "second"};
    System.out.println(Arrays.toString(strings));
    byte[][] byteStrings = convertToBytes(strings);
    strings = convertToStrings(byteStrings);
    System.out.println(Arrays.toString(strings));

}

private static String[] convertToStrings(byte[][] byteStrings) {
    String[] data = new String[byteStrings.length];
    for (int i = 0; i < byteStrings.length; i++) {
        data[i] = new String(byteStrings[i], Charset.defaultCharset());

    }
    return data;
}


private static byte[][] convertToBytes(String[] strings) {
    byte[][] data = new byte[strings.length][];
    for (int i = 0; i < strings.length; i++) {
        String string = strings[i];
        data[i] = string.getBytes(Charset.defaultCharset()); // you can chose charset
    }
    return data;
}

有一个字节[]从string []你有：

---

for one byte[] from string[] you have to:

• 来从每个字符串使用一些分隔符的字节数组CONCAT字节数组

从ByteArray的分裂由TE相同的分隔符
• 并创建String作为我
  如上所述。
