【java學習】IO FileOutputStream

剛剛學習了字節流中的FileOutStream：

 

package stream;

/**
 * 輸出文件字節流 --FileOutputStream 
 * 
 * @author Administrator
 *
 */

import java.io.*;

public class TestFile_OutputStream {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		// TODO Auto-generated method stub

		int b = 0;
		FileInputStream in = null;
		FileOutputStream out = null;

		try {

			in = new FileInputStream("H://forpassword.txt");  //讀入流
			out = new FileOutputStream("H://password.txt");   //讀出流
			
			while((b=in.read())!=-1){  //條件：直到完全數據讀取完畢    -1
				
				out.write((char)b);
			}
			
			//關閉字節流--良好的編程習慣
			in.close();  
			out.close();
			
			System.out.println();
			System.out.println("複製成功！");

		} catch (FileNotFoundException e) {
			
			System.out.println("WebBrowser.java未發現");
		}
		 catch (IOException e1) {

			 System.out.println("複製失敗！");
		}
	}
}
