以下示例显示java.io.BufferedReader.reset()方法的用法。
package com.jc2182;
import java.io.BufferedReader;
import java.io.StringReader;
public class BufferedReaderDemo {
public static void main(String[] args) throws Exception {
String s ="ABCDE";
StringReader sr = null;
BufferedReader br = null;
try {
sr = new StringReader(s);
// create new buffered reader
br = new BufferedReader(sr);
// reads and prints BufferedReader
System.out.println((char)br.read());
System.out.println((char)br.read());
// mark invoked at this position
br.mark(0);
System.out.println("mark() invoked");
System.out.println((char)br.read());
System.out.println((char)br.read());
// reset() repositioned the stream to the mark
br.reset();
System.out.println("reset() invoked");
System.out.println((char)br.read());
System.out.println((char)br.read());
} catch (Exception e) {
// exception occurred.
e.printStackTrace();
} finally {
// releases any system resources associated with the stream
if(sr!=null)
sr.close();
if(br!=null)
br.close();
}
}
}
让我们编译并运行以上程序,这将产生以下结果-
A
B
mark() invoked
C
D
reset() invoked
C
D
