用Java将字节数组写入文件 [英] Write byte array to file in java

问题描述

我想将字节数组写入txt文件.首先，我想在eclipse控制台中看到该数据，然后看到这些数据是真实的.但是，当我想将此数据写入txt文件时，问题出在清单本身. txt文件出现错误.

我的代码如下.

FileOutputStream fos;
try {
    fos = new FileOutputStream("/usr/text110.txt");
    fos.write(imageInByte);
    fos.close();
} catch (FileNotFoundException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
} catch (IOException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}

我的txt文件如下.如何将字节数组正确保存到文件中.请帮助我.

推荐答案

FileOutputStream fos = FileOutputStream("path/to/the/file/to/write/in");
fos.write(theByteArray);
fos.close();

将以字节形式写入字节数组 .

Will write the byte array in byte form.

FileOutputStream fos = FileOutputStream("path/to/the/file/to/write/in");
for (byte b : bytes) {
    fos.write(String.format("%02X ", b).getBytes());
}
fos.write(theByteArray);
fos.close();

将以易读的形式写入字节数组.

Will write byte array in human readable form.
