//正常的方法 先做input再做output
File file = new File("test.txt");
DataInputStream din = new DataInputStream(new FileInputStream(file);
int cnt = din.readInt();
din.close();
DataOutputStream dout = new DataOutputStream(new FileOutputStream(file));
dout.writeInt(++cnt);
dout.close();
//有问题的方法
File file = new File("test.txt");
DataInputStream din = new DataInputStream(new FileInputStream(file);
DataOutputStream dout = new DataOutputStream(new FileOutputStream(file));
int cnt = din.readInt();
dout.writeInt(++cnt);
din.close();
dout.close();
一做readInt()就跳出EOFException
怎麽会这样咧...
是因为我对同样的档案同时做存取的关系吗?
