示例

public class ClassA { private FileOutputStream stream; public void makeStream (File file) { try { stream = new FileOutputStream(file); } catch(FileNotFoundException fnfe) { //perform exception handling } //do something... } }

解决方案

为了避免资源泄漏，请确保对每个 java.io.FileOutputStream 都调用 close()。注意：此规则适用于所有形式的 FileOutputStream 构造函数。

public class ClassA { private FileOutputStream stream; public void makeStream (File file) { try { stream = new FileOutputStream(file); } catch(FileNotFoundException fnfe) { //perform exception handling } //do something... try { stream.close(); } catch(IOException ioe) { //perform exception handling } } }
