Before the introduction of generics, developers had to write separate methods for handling different data types, such as `getStringList()`, `getIntList()
The Struggle is Real (Before Generics)
2
Generics allow you to create code that works with various data types without code duplication.
Generics to the Rescue!
3
In generics, placeholders like `<T>` are used to represent the data type. The actual type is specified later in the code.

Type Safety: Generics catch errors at compile time, preventing runtime ClassCastException.
Reusability: With generics, you can write code once and use it with many data types.
Readability: Generics make your code clearer and more expressive.
Why Use Generics?
5
The built-in `ArrayList` class in Java uses generics. You specify the data type when creating the list.

By using generics, you can write cleaner, more robust, and maintainable Java code
