[英]How to write array of bytes to a binary file in Java
How to write an array of bytes b[i]
to a binary file in Java. 如何用Java将字节数组b[i]
写入二进制文件。
I need to write those bytes it into a "binary file" to be able to read it later using hex editor (AXE). 我需要将那些字节写入“二进制文件”,以便以后使用十六进制编辑器(AXE)读取它。
Some readers might be confused by "binary file", by binary file I don't mean a file filled by zeros and ones, I mean machine-readable form, something like this : binary files in text editor 某些读者可能会对“二进制文件”感到困惑,对于二进制文件,我不是指用零和一填充的文件,而是指机器可读的形式,例如: 文本编辑器中的二进制文件
The hex editor suppose to read this data, hex editor 十六进制编辑器假定要读取此数据, 十六进制编辑器
From what I understand I need to byte stream that data into a file Is there a command I could use for this purpose. 据我了解,我需要将数据按字节流式传输到文件中,是否可以使用此命令。
Any code would be appreciated. 任何代码将不胜感激。
Just write the byte[] to a FileOutputStream pointing to the file: 只需将byte []写入指向文件的FileOutputStream即可:
private static void writeBytesToFile(byte[] b, String f) {
try (FileOutputStream out = new FileOutputStream(f)){
out.write(b);
}
catch (IOException e) {
e.printStackTrace();
}
}
