Question

怎么用JAVA程序从一个TXT文件中按指定行读取内容?

Answer 1

基本结构如下，楼主可参考一下:
try{
pwd=System.getProperty("user.dir");//获取当前目录
FileReader
fr
=
new
FileReader(pwd
+
"\\1.txt");
BufferedReader
br
=
new
BufferedReader(fr);
String
Line
=
br.readLine();
while
(Line
!=
null)
{
System.out.println(Line);
Line
=
br.readLine();
}
br.close();
fr.close();
}catch(IOException
ex){}
