以下示例显示java.io.CharArrayReader.reset()方法的用法。
package com.jc2182;
import java.io.CharArrayReader;
import java.io.IOException;
public class CharArrayReadDemo {
public static void main(String[] args) { CharArrayReader car = null;
char[] ch = {'A', 'B', 'C', 'D', 'E'};
try {
// create new character array reader
car = new CharArrayReader(ch);
int value = 0;
// read till the end of the stream
while((value = car.read())!=-1) {
// convert integer to char
char c = (char)value;
// print characters
System.out.print(c + " ");
}
// reset invoked
car.reset();
System.out.println("\nReset() invoked");
// read till the end of the stream
while((value = car.read())!=-1) {
// convert integer to char
char c = (char)value;
// print characters
System.out.print(c + " ");
}
} catch(IOException e) {
// if I/O error occurs
e.printStackTrace();
} finally {
// releases any system resources associated with the stream
if(car!=null)
car.close();
}
}
}
让我们编译并运行以上程序,这将产生以下结果-
A B C D E
Reset() invoked
A B C D E
