Can anyone help me with this program?

Question

A real estate company keeps in a text file information about properties ( house,
apartment, and land)and their prices.

Each line in this file is of the following form: property_id property_type price (e.g. 12123 apartment 600000).

Note that the file is space delimited (one space between each field and the next one).
Write a program that reads the information from this file and calculates the following totals then write them in another file.
total price for houses apartments lands

Answer 1

//I would use the Scanner class with the File as input:
File f = new File("path/filename.txt");
Scanner scan = new Scanner(file);

//While the end of the File is not reached you can read out the data and store it in variables or Arrays:
int result = 0;
while(scan.hasNext()){
int price = scan.next();
result += price;
}

//write the result to a file (using PrintWriter):

//remember to use try-catch Blocks when working with files but your IDE should suggest them anyway. This is one way to do it obviously there are many more and better ways.
