[Solved] Why you can’t just paste method to make it work?

Introduction

When it comes to programming, it can be tempting to think that you can just copy and paste a method from one program to another and expect it to work. Unfortunately, this is not the case. There are a variety of reasons why you can’t just paste a method to make it work, and understanding these reasons can help you become a better programmer. In this article, we’ll discuss why you can’t just paste a method to make it work and how you can use this knowledge to your advantage.

Solution

The reason you can’t just paste a method to make it work is because the code needs to be tailored to the specific problem you are trying to solve. Different problems require different solutions, and the code needs to be written to address the specific issue. Additionally, the code needs to be written in the language that the program is written in, and it needs to be compatible with the existing code. Without taking all of these factors into account, simply pasting a method into a program is unlikely to work.


String is immutable. so, sub.toUpperCase() doesn’t change the string internals. It just returns you a new string value that is uppercased:

To uppercase sub, rather assign sub to the result of the toUpperCase() method like so:

sub = sub.toUpperCase();

That way, you return a new uppercase string.

Solved: Why You Can’t Just Paste Method to Make It Work?

Have you ever tried to copy and paste a method from one program to another, only to find that it doesn’t work? It can be incredibly frustrating, especially if you’re in a hurry. But why can’t you just paste a method and make it work?

The answer lies in the way that different programs are designed. Each program is written in a specific programming language, and the code that makes up the program is written to work with that language. When you copy and paste a method from one program to another, the code is not written in the same language, so the program won’t understand it.

In addition, different programs have different ways of organizing their code. Even if the code is written in the same language, the way it is organized may be different. This means that the code you copied and pasted may not be in the right place, or it may not be formatted correctly for the new program.

Finally, different programs may have different requirements for the code. For example, one program may require that the code be written in a certain way, while another program may require that the code be written in a different way. If the code you copied and pasted doesn’t meet the requirements of the new program, it won’t work.

So, the next time you try to copy and paste a method from one program to another, remember that it won’t always work. You may need to rewrite the code in the new program’s language, or you may need to make sure that the code is organized and formatted correctly. With a little bit of effort, you can make sure that your code works in the new program.
