以下示例显示java.io.CharArrayReader.close()方法的用法。
package com.jc2182;
import java.io.CharArrayReader;
import java.io.IOException;
public class CharArrayReaderDemo {
public static void main(String[] args) { CharArrayReader car = null;
char[] ch = {'H', 'E', 'L', 'L', 'O'};
try {
// create new character array reader
car = new CharArrayReader(ch);
// closes the character array stream
car.close();
// read the character array stream
car.read();
} catch(IOException e) {
// if I/O error occurs
System.out.print("Stream is already closed");
} finally {
// releases any system resources associated with the stream
if(car!=null)
car.close();
}
}
}
