示例

public class ClassA { private BufferedReader reader; public void makeReader (Reader r) { reader = new BufferedReader(r); //do something... } }

解决方案

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

public class ClassA { private BufferedReader reader; public void makeReader (Reader r) { reader = new BufferedReader(r); //do something... try { reader.close(); } catch(IOException ioe) { //perform exception handling } } }
