应用FileInputStream类,编写应用程序,从磁盘上读取一个Java程序,并将源程序代码显示在屏幕上。(被读取的文件路径为:d:/myjava/Hello.java 内容自己决定);
package stage3; import java.io.BufferedInputStream; import java.io.File; import java.io.FileInputStream; import java.io.IOException; import java.io.PrintStream; public class Test6 { public static void main(String[] args) { // TODO Auto-generated method stub File f = new File("d:/data/Hello.java"); try(FileInputStream fin = new FileInputStream(f); BufferedInputStream bin = new BufferedInputStream(fin); PrintStream ps = new PrintStream(System.out); ){ byte [] b = new byte[(int)f.length()]; bin.read(b); ps.println(new String(b,"gbk")); }catch(IOException e) { e.printStackTrace(); } } }
