Hello my friends,
Today I want to share with you a little bit more of my learning progress with Java.
Banking Application (for learning and fun purposes)
This program simulates a banking app where you can 'play' and learn a bit more about Java commands. I'm still at a beginner level, so every progress is a victory!
As you will se below, in this lesson I was learning how to use the "if", "else", and "else if" statements.
I met a friend of mine last weekend, and he also taught me how to use the "while" command, which makes the program rerun automatically. You will see that every time I wrote "stop = false;", the program stopped rerunning automatically.
If you are into learning Java, follow me and I will keep you updated with my progress!
Have a great day and let's code together!

Eai meus amigos da Hive,
Esse programa simula um aplicativo de banco, onde é possível "brincar" e aprender um pouco mais sobre os comando de Java. Ainda estou num nível principiante, portanto cada progresso é uma vitória!
Aplicativo Bancário (para fins de aprendizado e diversão)
Como você verá abaixo, nesta lição eu estava aprendendo a usar as instruções "if", "else" e "else if". Encontrei um amigo meu no último fim de semana, e ele também me ensinou a usar o comando "while", que faz o programa ser executado automaticamente. Você verá que toda vez que escrevi "stop = false;", o programa parou de ser executado automaticamente.
Se você está interessado em aprender Java, siga-me e eu vou mantê-lo atualizado com meu progresso!
Tenha um ótimo dia e vamos codar juntos!

// related to a specific condition, while in the exam program
// else means ANYTHING ELSE THAN THE MINIMUM EXAM RESULT.
// in this banking program, we are giving an ORDER for the computer to OBEY.
// I can use a lot of IFs, but i need to remember that all of them will run at the same time. for example:
// if MALE=true,
// run the following orders: offer t-shirts, shorts, and shaving accessories.
// if olderthan40 = true, offer viagra, etc. take it easy for now
