在這段代碼中,我收到了's'和'p'的資源泄漏警告。這個警告是否有效?虛假資源泄漏警告?
try (StringWriter s = new StringWriter(); PrintWriter p = new PrintWriter(s)) {
p.print(InetAddress.getLocalHost().getHostName());
p.print('/');
Enumeration<NetworkInterface> e = NetworkInterface.getNetworkInterfaces();
while (e.hasMoreElements()) {
NetworkInterface i = e.nextElement();
System.out.println(i);
if (i.getHardwareAddress() == null || i.getHardwareAddress().length == 0)
continue;
for (byte b : i.getHardwareAddress())
p.printf("%02x", b);
return s.toString();
}
throw new RuntimeException("Unable to determine Host ID");
}
在Eclipse的編譯器中可能是錯誤的?嘗試在try塊外拋出異常 – Adrian
這就是我所懷疑的,但嘗試與資源對我來說仍然有點新,所以我想三重檢查。 –
也許你可以在Netbeans或IntelliJ IDEA中打開你的代碼,並檢查他們說什麼。 – Adrian
