此文献介绍字节输出输入流
字节输入流 InputStream 将内容以字节(byte)的形式输入,如果要输入普通文本,假设文本内容为
通过以下代码:
public class CeShi {
public static void main(String[] args) {
InputStream in;
try {
in = new FileInputStream(new File(“F:\表.txt”));
byte[] bs = new byte[100];//缓冲区
int count = 0;
while((count = in.read(bs,0,bs.length))!=-1){
String str = new String(bs,0,count);
System.out.println(str);
}
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}//文本路径
catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}finally {
try {
if(in != null) {
in.close();
}
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
}运行代码结果为:
字节输出流,将普通文本以字节的形式输出,代码部分相较输入流较少。
public class CeShi {
public static void main(String[] args) {
OutputStream out = null;
try {
out = new FileOutputStream(new File(“F:\表.txt”));
out.write(new String (“天下大同”).getBytes());
out.flush();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}finally {
try {
if(out != null) {
out.close();
}
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
代码运行后:
