예제

public class ClassA { public void makeStream (Writer writer) { try { BufferedWriter stream = new BufferedWriter(writer); stream.write(7); //do something... stream.close(); } catch (IOException e) { //stream leaked... } } }

솔루션

자원 누수를 피하려면 모든 java.io.BufferedWriter에서 close()가 호출되는지 확인하십시오. 참고: 이 규칙은 모든 BufferedWriter 생성자 형식에 적용됩니다.

public class ClassA { public void makeStream (Writer writer) { BufferedWriter stream = new BufferedWriter(writer); try { stream.write(7); //do something... } catch (IOException e) { //do something... } finally { if (stream != null) { try { stream.close(); } catch(IOException e) { //do something... } } } } }
