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!
