A simple program that will write a byte[] into a file.
一个将 byte[] 写入文件的简单程序。
import java.io.File;
import java.io.FileOutputStream;
public class BytesToFile {
public static void main(String[] args) {
byte[] demBytes = null; //instead of null, specify your bytes here.
File outputFile = new File("LOCATION TO FILE");
try ( FileOutputStream outputStream = new FileOutputStream(outputFile); ) {
outputStream.write(demBytes); //write the bytes and your done.
} catch (Exception e) {
e.printStackTrace();
}
}
}
Note: The try-catch statement requires a Java Version >= 1.7. remember to change the bytes from null to correspond your byte array.
注意：try-catch 语句需要 Java 版本 >= 1.7。请记住将字节从 null 更改为对应于您的字节数组。

try this
尝试这个
Files.write(Paths.get("filename"), bytes);
