示例

public class ClassA { public void makeStream (OutputStream oStream) { PrintStream stream = new PrintStream(oStream); stream.write(7); //do something... } }

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 { public void makeStream (OutputStream oStream) { PrintStream stream = new PrintStream(oStream); stream.write(7); //do something... stream.close(); } }
