JavaIO之StringReader 与 StringWriter
CharArray,通过构造方法传递 CharArrayWriter 是写, 写入到一个CharArray中去,所以它内部提供了一个CharArray 用来保存数据 StringReader 和 StringWriter 也是类似的道理 String作为数据源 StringReader 是读, 从一个String中读取,所以需要一个String ,通过构造方法传递 StringWriter是写, 写入到一个String 构造方法 StringReader只有一个版本的构造方法,接受一个String作为参数String str指向这个字符串length 为字符串长度next为读取元素的下标索引mark为标记点 StringWriter 向后跳读不可能倒过字符串的开头 如果读取或跳读了整个字符串，则此方法无效且始终返回 0 了解到他可以为负数,而且返回值也可能是负数 close close方法仅仅是置空 StringWriter append(char c)public StringWriter append(CharSequence csq)public StringWriter append(CharSequence csq

浅谈StreamWriter类
学习TextWriter类之后，我们会使用StringWriter来对TextWriter类做一个简单的练习，在之前简单认识一下StringWriter： public class StringWriter : TextWriter { public StringWriter(); public StringWriter(IFormatProvider formatProvider); public StringWriter(StringBuilder sb); public StringWriter(StringBuilder sb, IFormatProvider formatProvider _sb.ToString(); } 我们使用StringWriter来对TextWriter类做一个简单的练习： using (TextWriter writer = new StringWriter( 最后我们看看TextWriter，StringWriter和StreamWriter的OO图： ?

理解和运用Java中的append()方法
Java中的append()方法是StringBuffer和StringBuilder类以及StringWriter类中的一个重要方法，用于在现有字符串的尾部追加字符或者字符串，构建和修改字符串内容 类中的应用 不仅仅是StringBuffer和StringBuilder，Java中的StringWriter类也同样支持append()方法，但这是用于将内容保存到字符流中。 https://s.10zhan.com // 创建StringWriter对象，调用append方法将字符保存到字符流 StringWriter stringWriter = new StringWriter (); stringWriter.append("Hello"); stringWriter.append(" World"); System.out.println(stringWriter.toString ()); StringWriter的每次调用append()方法，实际上是将字符串保存到内部的缓冲区中，最后通过toString()方法一次性取出所有的字符串。

dotnet 使用 IndentedTextWriter 辅助生成代码时生成带缩进的内容
其中 StringWriter 用于辅助写入 StringBuilder 对象，基本输出限制在内存里面。 而 StreamWriter 则是输出到 Stream 里，至于这个 Stream 是文件还是网络，那就看你的心情了 作为例子，咱使用 StringWriter 作为 IndentedTextWriter IndentedTextWriter 写入的内容，最终将会写入到 StringBuilder 里面，初始化的代码如下 var stringBuilder = new StringBuilder(); var stringWriter = new StringWriter(stringBuilder); var indentedTextWriter = new IndentedTextWriter(stringWriter, " " = new StringWriter(stringBuilder); var indentedTextWriter = new IndentedTextWriter(stringWriter, " "

java string转inputstream(substring截取字符串)
StringWriter writer = new StringWriter(); IOUtils.copy(inputStream, writer, encoding); String theString = writer.toString(); 首先把inputStream转换为StringWriter，然后使用StringWriter获取字符串。
