To make a class Immutable, we need to ensure that its state cannot be modified after creation.

• Make all fields final and private

• Do not provide any setters

Replace odd numbers with their square using stream on a given List of Integers.

• Use stream() method to convert the List of Integers into a stream.

• Use map() method to apply the square function to each odd number.

• Use filter() method to filter out even numbers.

• Use collect() method to convert the stream back to a List.

• Example: List numbers = Arrays.asList(1, 2, 3, 4, 5); numbers.stream().map(n -> n % 2 == 0 ? n : n * n).col
