经过不断尝试终于得到了java中IO的的相对路径问题
啥也不说看例子吧
public static void main(String[] args) {
try {
FileInputStream fin = new FileInputStream(".\\src\\Hello.java");
FileOutputStream fou = new FileOutputStream("./src/hh.java");
while (fin.read()!=-1) {
int b=fin.read();
fou.write(b);
System.out.print((char)b);
}
fin.close();
fou.close();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
try {
FileInputStream fin = new FileInputStream(".\\src\\Hello.java");
FileOutputStream fou = new FileOutputStream("./src/hh.java");
while (fin.read()!=-1) {
int b=fin.read();
fou.write(b);
System.out.print((char)b);
}
fin.close();
fou.close();
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
