Usage

From source file:Main.java

public static byte[] readStream(InputStream inputStream) throws Exception {
    ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
    byte[] buffer = new byte[1024];
    int len = 0;//from www  . jav a 2s  .  c o  m
    while ((len = inputStream.read(buffer)) != -1) {
        outputStream.write(buffer, 0, len);
    }
    outputStream.close();
    inputStream.close();
    return outputStream.toByteArray();
}

From source file:Main.java
