示例

public class ClassA { private DataInputStream stream; public void makeStream (InputStream is) { stream = new DataInputStream(is); //do something... } }

解决方案

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

public class ClassA { private DataInputStream stream; public void makeStream (InputStream is) { stream = new DataInputStream(is); //do something... try { stream.close(); } catch(IOException ioe) { //perform exception handling } } }
