示例

public class ClassA { private PrintStream stream; public void makeStream (OutputStream os) { stream = new PrintStream(os); //do something... stream.flush(); } }

解决方案

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

public class ClassA { private PrintStream stream; public void makeStream (OutputStream os) { stream = new PrintStream(os); //do something... stream.flush(); stream.close(); } }
