Implement a program that asks the user to enter three integers and writes them to a text file called ints.txt.
Implement a program that asks the user to enter three doubles and writes them to a binary file called doubles.bin.
Implement a program that reads all of the integers in ints.txt and displays the sum.
Modify the first program so that it appends to ints.txt rather than overwriting the file each time the program runs.
Implement a program that reads two doubles from doubles.bin and displays larger of the two numbers.

Implement the following utility class:

classDiagram
    class ListGenerator {
        -rand: Random$
        +generateInts(max: int) List~Integer~$
        +generateDoubles(max: int) List~Double~$
        +generateStrings(max: int) List~String~$
        -generateString(max: int) String$
    }

where the last method generates a string containing a random number of digits (no more than max) and each other method generates a random number of desired objects (no more than max).

Implement the following methods:
- void writeDoubles(Path path, List<Double> list) — write the list to a text file with one value on each line
- static void main(String[] ignored) — program that generates a list of up to ten doubles and writes it to a file called nums.txt
Implement the following methods:
- void readDoubles(Path path, List<Double> list) — reads a text file filled with doubles and adds each double to the list.
- static void main(String[] ignored) — a different program that reads up to ten doubles and from a file called nums.txt and displays the sum of the values
Implement the following methods:
- void writeInts(OutputStream out, List<Integer> list) — write the list to a text file with one value on each line
- void writeStrings(OutputStream out, List<String> list) — write the list to a text file with one value on each line
Implement the following methods:
- void readInts(InputStream in, List<Integer> list) — reads a text file filled with integers and adds each integer to the list.
- void readStrings(InputStream in, List<String> list) — reads a text file filled with strings and adds each string to the list.
Refactor the writeDoubles() and readDoubles() methods so that they accept a stream instead of a path.
Implement a program that writes a random number of doubles, followed by a random number of strings, followed by a random number of integers.
Implement another program that reads all numbers in a file ignoring all strings and displays the sum of all the numbers.
Implement another program that reads all the strings in the file and ignores all integers and doubles..
