File f = new File("new.txt");
try{
FileOutputStream fos = new FileOutputStream(f); //输出流
Byte[] bu = "www.baidu.com".getBytes(); //Type mismatch: cannot convert from byte[] to Byte[]
fos.write(bu); //The method write(int) in the type FileOutputStream is not applicable for the arguments (Byte[])
fos.close();
}catch(Exception e){
e.printStackTrace();
}
try{
FileInputStream fis = new FileInputStream(f); //输入流.
Byte[] buf = new Byte[1024];
int len = fis.read();
System.out.println(new String(buf,0,len)); //The constructor String(Byte[], int, int) is undefined
}catch(Exception e){
e.printStackTrace();
}问题补充:
为什么我用eclipse写运行就有上面的问题,用命令去敲的时候就不行了?
