以下示例显示java.io.CharArrayWriter.close()方法的用法。
package com.jc2182;
import java.io.CharArrayWriter;
public class CharArrayWriterAppendDemo {
public static void main(String[] args) {
CharArrayWriter chw = null;
try {
// create character array writer
chw = new CharArrayWriter();
// declare character sequence
CharSequence csq = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
// closes the stream
chw.close();
// append character sequence to the writer
chw.append(csq);
// prints out the character sequences
System.out.println(chw.toString());
} catch(Exception e) {
// for any error
e.printStackTrace();
} finally {
// releases all system resources from writer
if(chw!=null)
chw.close();
}
}
}
让我们编译并运行以上程序,这将产生以下结果-
ABCDEFGHIJKLMNOPQRSTUVWXYZ
