在Java中使用ReadFile方法需要帮助吗？

Question

I'm stuck with this question and was hoping to get help here. I just need to know how to get started because that's what I'm stuck on.

Here's the question:

Assume file employees.txt exists and has the following format: name id number gross pay Write method readFile. readFile accepts an id number, searches file, employees.txt, for the employee with that id number, and returns their gross pay.

Answer 1

here you can see the basic steps.

1.First create a File object like this:

File myfile = new File("path of the particular file");

2.Create FileReader object and give the created myfile object as a parameter.

FileReader fr = new FileReader(myfile);

3.Make buffered reader object.

BufferedReader br = new BufferedReader(fr);

4.now you can read the file line by line and put it into a string as like below. String str = br.ReadLine(); System.out.println(str);
