Why is it important to override the equals() method in your class?

Overriding the equals() method is important for correctly comparing objects by content rather than by reference. By default, in Java, the equals() method compares references (i.e., checks if variables point to the same object).

If you want to consider two objects equal when certain fields match (for example, ID, name, etc.), you need to override equals().

Example:

@Override
public boolean equals(Object obj) {
    if (this == obj) return true;
    if (obj == null || getClass() != obj.getClass()) return false;
    MyClass other = (MyClass) obj;
    return Objects.equals(field1, other.field1) &&
           Objects.equals(field2, other.field2);
}

Without overriding equals(), collections like HashSet or search methods may not work correctly.
