java 的 io 相比别的语言真是啰嗦而复杂. 发现有些人在做 io 时并没有处理异常甚至没有关闭, 有的人做了异常处理但是然并卵, 做的是错的. 大家是怎么做的, 非java7

发现比较好的一种方法
public void test createSource(byte[] bytes) throws IOException {
File file = createFile();
OutputStream out = new FileOutputStream(file);
try {
out.write(bytes);
} finally {
out.close();
}
}
}
public void test createSource(byte[] bytes) throws IOException {
File file = createFile();
OutputStream out = new FileOutputStream(file);
try {
out.write(bytes);
} finally {
out.close();
}
}
}
