How to use BufferedReader?

[ProgramBeginner]

How do I use BufferedReader to read whole paragraph? I dont know how to start it except typing:

class Reader throws IO Exception
{
BufferedReader reader - new BufferedReader();
}


I know Im supposed to use readline() but I just dont know how to put it......
BTW can Bufferedreader read strings inside a vector?

File file = new File(filePath);
try {
    BufferedReader br = new BufferedReader(
                        new InputStreamReader(
                        new FileInputStream(file)));
    String line;
    while((line = br.readLine()) != null)
        System.out.println(line);
    br.close();
} catch(IOException e) {
    ...
}

Vector<String> v = new Vector<String>();
for(int j = 0; j < 5; j++) {
    v.add(String.valueOf(j));
}
// retrieve the third element
String s = v.get(2);
