stringwriter类是writer类的子类，它将字符串写入输出流。为了写入字符串，该字符流将字符串收集到字符串缓冲区中，然后构造一个字符串。 stringwriter的缓冲区根据数据自动增长。 stringwriter类的重要方法有write()、append()、getbuffer()、flush()和close()。 p>
语法public class stringwriter extends writer
示例import java.io.*;public class stringwritertest { public static void main(string args[]) { string str = "welcome to tutorials point"; try { stringwriter sw = new stringwriter(); sw.write(str); stringbuffer sb = new stringbuffer(); sb = sw.getbuffer(); system.out.println("stringbuffer: "+ sb); system.out.println("string written by stringwriter: "+ sw); sw.close(); } catch (ioexception ioe) { system.out.println(ioe); } }}
输出stringbuffer: welcome to tutorials pointstring written by stringwriter: welcome to tutorials point
以上就是stringwriter在java中的重要性是什么？的详细内容。
