How does the single responsibility principle facilitate the work of a programmer?

The Single Responsibility Principle (SRP) states that every class or module should have only one reason to change, meaning it should be responsible for a single specific task.

This makes it easier for programmers in the following ways:

• Simplifies understanding of the code: when a class handles only one task, it is easier to understand and maintain.
• Facilitates testing: testing small modules is easier because they have limited functionality.
• Increases flexibility: changes in one part of the system do not affect others, reducing the risk of errors.
• Improves reusability: modules with a single responsibility are easier to reuse in different places.

For example, in an Android application, a class responsible for loading data from the network should not handle displaying this data — that is the task of another class. This approach makes the code more modular and easier to maintain.
