这些代码能转成groovy代码吗：ByteArrayOutputStream outputStream = new ByteArrayOutputStream FileInputStream inputStream = new FileInputStreamfile byte buf = new byte1024 int len = -1 w

可以将这些代码转换为Groovy代码。以下是转换后的代码：

import java.io.ByteArrayOutputStream import java.io.FileInputStream import java.io.FileOutputStream

ByteArrayOutputStream outputStream = new ByteArrayOutputStream() FileInputStream inputStream = new FileInputStream(file) byte[] buf = new byte[1024] int len = -1 while ((len = inputStream.read(buf)) != -1) { outputStream.write(buf, 0, len) } outputStream.flush() byte[] data = outputStream.toByteArray() //密钥 byte[] key = [2, 0, 2, 3, 0, 7, 7, 7] byte[] result = new byte[data.length] for (int i = 0; i < data.length; i++) { int index = i % key.length byte add = key[index] int newVal = data[i] ^ add result[i] = (byte) newVal } File newFile = new File(file.parent, "config.dat") FileOutputStream out = new FileOutputStream(newFile) out.write(result, 0, result.length) out.flush() out.close(
