Convert boolean inside if statement

Hello, I am working on a program where I am using a particular logic for a flag, I am declaring a boolean variable, and then making an if statement that executes if the statement and then add value to an array, but I want to alternatively add values to my array. EG I have 1001 I want to add 1 in array1, 0 in both arrays, 0 in both arrays, 1 in array1. This is how I have written this in code. But the problem is that the boolean is always true, it doesn't get flase even after the if statement has executed. This is my code: ``` for(int i = 0; i < reversedBinaryValue.size(); i++) {...

fix code :)

hello how do you fix this?

Help for revisiting Java

Hi everyone!👋 I hope you're all doing well. I’m Portuguese and I'm a student, and I'm currently revisiting Java. I studied it 2 years ago, but I feel like I've forgotten a lot since then, especially regarding Object-Oriented Programming concepts like classes, objects, inheritance, and polymorphism. If anyone has any suggestions for resources or tutorials, I would really appreciate it! I’m eager to learn and improve, but I feel a bit lost right now. As you know, most articles are in English, so I don’t mind reading in English....

Personal-finance app dividing into class

Hi! Like most people starting out with coding, I've made a code of a finance-app in one single file.

Where does Spring's HttpServiceProxyFactory create the client proxy implementation?

I am trying to understand how using the "@HttpExchange" annotation works. From what I know, it creates an implementation class that has the Http methods I've defined in my interface. But unlike lombok annotations I can't find in my project how this class is implemented? Or is there no actual class that's being generated at compile time? I can't seem to find resources going into this, and looking at the actual source code just left me confused. "@HttpExchange": https://docs.spring.io/spring-framework/docs/current/javadoc-api/org/springframework/web/service/annotation/HttpExchange.html...
