JavaIO之StringReader 与 StringWriter
CharArray 中读取,所以需要一个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中去,所以它内部提供了一个StringBuffer中用来保存数据 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 为读取元素的下标索引mark为标记点 StringWriter内部有两个版本的构造方法在构造方法内部初始化了内部的buf 创建了一个StringBuffer一个指定大小 一个不指定 其他方法 StringReader int len) throws IOException 读取len个数的字符到指定的字符数组cbuf[] ,保存到指定位置off可以看得出来,底子还是依赖StringBuffer本身 标记相关StringReader

java中讲讲StringReader的用法，举例？
2.1 StringReader的用法 StringReader是Reader的继承类，从字面上就可看出，它是专门处理字符串的。 public static void main(String args[]) throws Exception { // /from multiline string to StringReader ; System.out.println(s); /* A character stream whose source is a string. */ StringReader in2 = new StringReader(s); int c; /*in2.read() Read a single character,(qixy: two bytes
