Example

1public class User {  
2    private String name;  
3    private int age;  
4
5    // YAGNI violation: A method to calculate the user's retirement age,  
6    // which is not currently necessary for the User class.  
7    public int calculateRetirementAge() {  
8        return 65 - this.age;  
9    }  
10}

Description

Keep things simple and avoid investing time and effort in building features based on assumptions about what the future might hold.

YAGNI is like a friendly warning against filling your backpack with too many "just in case" items for a hike; it only weighs you down.

This approach aligns with Agile methodologies, which emphasize iterative development, responding to changes, and streamlining work to what's currently valuable.
