以下示例显示java.io.CharArrayWriter.toString()方法的用法。
package com.jc2182;
import java.io.CharArrayWriter;
public class CharArrayWriterDemo {
public static void main(String[] args) {
char[] ch = {'A','B','C','D','E'};
CharArrayWriter chw = null;
try {
// create character array writer
chw = new CharArrayWriter();
// write character buffer to the writer
chw.write(ch);
// get buffered content as string
String str = chw.toString();
// print the string
System.out.print(str);
} catch(Exception e) {
// for any error
e.printStackTrace();
} finally {
// releases all system resources from writer
if(chw!=null)
chw.close();
}
}
}
