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();
}
}
