I still remember the first time I saw a builder chain: it read like a sentence and yet compiled into efficient Java. That moment stuck with me because it solved a daily pain point—cluttered setup code with scattered intermediate variables. If you've ever felt that the shape of your code hides the intent, method chaining […]

I still remember the first time a teammate "fixed" a bug by making a field public. The issue went away, but a week later we were chasing a regression caused by a class in another package mutating that field at the wrong time. That's the real reason access modifiers matter: they don't just control visibility, […]
The public keyword is an access modifier, which is used to set the access level/visibility for classes, fields, methods and properties. C# has the following access modifiers: ... There's also two combinations: protected internal and private protected. For now, lets focus on public and private modifiers.

Public and private In C# a public member can be called from external locations. Used on members, classes and method declarations, public is not the default accessibility. Meanwhile, a private method cannot be called from outside its class. It can be called only from other class methods—this promotes information hiding. Public example
