一，打印流

二，常用方法

三，案例

package Print.sd;

import java.io.FileNotFoundException;
import java.io.PrintStream;
import java.nio.charset.Charset;

public class Main {
    public static void main(String[] args) throws FileNotFoundException {
        try ( //1,创建一个打印流管道
              PrintStream da =new  PrintStream("C:\\untitled1\\untitled\\src\\zifuji\\fangfa", Charset.forName("GBK"));
              ){
            da.println(54);
            da.println("ghfqohe");
            da.println("ghfqohe");
            da.println("星火");
            da.println("星火");
            da.println("星火");


        } catch (Exception e) {
            e.printStackTrace();
        }

    }
}

package Print.sd;

import java.io.FileNotFoundException;
import java.io.PrintWriter;

public class Main {
    public static void main(String[] args) throws FileNotFoundException {
        try ( //1,创建一个打印流管道
              PrintWriter da =new PrintWriter("C:\\untitled1\\untitled\\src\\zifuji\\fangfa");
              ){

            da.write("fhadiuf");
            da.write("gfhrgiudnf");


        } catch (Exception e) {
            e.printStackTrace();
        }

    }
}
