Question

使用BufferedReader类，其中有个方法是readLine();只能读取一个文本行。我想读第二行怎么办？

BufferedReader filebr = new BufferedReader(new FileReader(sourceName));
try {
String str=filebr.readLine();
} catch (IOException e) {
e.printStackTrace();
}

Answer 1

BufferedReader filebr = new BufferedReader(new FileReader(sourceName));
try {
String str=filebr.readLine();
String str1=filebr.readLine();//第二行
String str2=filebr.readLine();//地三行
...
} catch (IOException e) {
e.printStackTrace();
}

Answer 2

再读一次
