java中讲讲PrintWriter的用法，举例？

1.2 PrintWriter的用法

PrintWriter和PrintStream类似，只不过PrintStream是针对字节流的，而PrintWriter是针对字符流的。

例：1.2.1
import java.io.*;
public class TestMark_to_win {
public static void main(String args[]) throws Exception {
String s1 = "我们" + "\n";
String s2 = "你们" + "\n";
PrintWriter p = new PrintWriter("c:/out.txt");
p.println("output" + s1);
p.println("output" + s2);
/*without using the following statement, the file name can be write out, but the content of the file is empty. */
p.close();
}
}
