# Project

# Project rules

• Choose and share your idea with the teachers before 01.11
• You are working on the project until the end of the course
• You can work in groups (you should tell us that you are working in a group)
• Try to use what we learnt during the course
• You can use something that was not covered during the course
• You can (but don't have to) use one of our ideas

# Project ideas 💡 💡 💡

# Text analysis 📖

# Description:

A user can enter a text using the console. The application should calculate a statistics and show it to the user:

• amount of the sentences
• amount of the words
• the longest word
• the longest sentence
• top 5 the most popular words in the text

# Bonus: ↗️

If you finished the exercise, here some ideas how you can make it more complex and use something else:

• Read a text from a file
• Application receives a path to a folder, checks all files in this folder and create a statistics as a json file for each file + a statistics for the folder, that contains:
  • How many files were processed
  • The biggest text
  • The smallest text
  • The longest sentence
  • The longest word
  • The top 5 the most popular words across all the texts
• Add tests for your application

# You will use from the course: ✅

• OOP
• Data Structures
• Tests
• File IO

# You will need to learn yourself: 🔍

• String operations

# Phone Index 📱

# Description:

A user can enter a text using the console. Which contains phone number and name and they should be able to

• save number
• add new numbers later
• search for contact by name or phone number

# Bonus: ↗️

If you finished the exercise, here some ideas how you can make it more complex and use something else:

• user can search for number and delete it from phone index

# You will use from the course: ✅

• OOP
• Data Structures
• Tests
• File IO

# You will need to learn yourself: 🔍

• String operations

# Accounting software 📈

# Description:

A user can enter expenses and earnings using a console. They should be able to:

• retrieve all previously inserted expenses and earnings
• receive summaries and balances
• save and load data to and from file, to use it later on

# Bonus: ↗️

If you finished the exercise, here some ideas how you can make it more complex and use something else:

• have a simple user management system that allows different users to register and log in the system, and store their data in different files
• use a real db!

# You will use from the course: ✅

• OOP
• Data Structures
• Tests
• File IO

# You will need to learn yourself: 🔍

• String operations
• Potentially, simple database operations

# Twitter analysis 🐦

# Description:

A lot of things are said on Twitter every day - the analysis of tweets can be very valuable! The user of your program should be able to select a tag/topic, anx the program could fetch the last tweets on the topic and return some basic statistics

• most mentioned words (removing very common words?)
• most used emojis
• most active user

# Bonus: ↗️

If you finished the exercise, here some ideas how you can make it more complex and use something else:

• you could use a graphing library to actually output nice graphs!

# You will use from the course: ✅

• OOP
• Data Structures
• Tests
• File IO

# You will need to learn yourself: 🔍

• using Twitter Java API (maybe http://twitter4j.org/en/? )
• potentially, using a graphing library
