问题描述

是否有一种干净简单的方法将 java.io.PrintWriter 的实例转换为 java.io.PrintStream ?

解决方案

首先从 Writer 获得 OutputStream .请参阅此问题

然后将其作为参数传递给 PrintStream 构造函数:

  OutputStream os = new WriterOutputStream(writer);PrintStream ps =新的PrintStream(os); 

更新: commons-io 2.0具有 解决方案

First obtain an OutputStream from the Writer. See this question

Then pass it as argument to the PrintStream constructor:

OutputStream os = new WriterOutputStream(writer);
PrintStream ps = new PrintStream(os);

Update: commons-io 2.0 has WriterOutputStream, so use it.
