✅ Example: Average of All Numbers in a Set 🔹 Output:

✅ Example: Sum of All Numbers in a Set 🔹 Output: ✅ Breakdown Method Description stream() Turns the Set into a Stream mapToInt() Converts Integer objects to primitives sum() Sums all elements in the IntStream 🧠 Bonus: Using reduce() If … Continue reading →

To find the minimum number in a Set, you can use the min() method in a stream — just like you did with max(). ✅ Example: Find Min in a Set 🔹 Output: ✅ Explanation Method Purpose .stream() Turns the … Continue reading →

👑 To find the maximum number in a Set using Java Streams, you can use the max() terminal method with a comparator. ✅ Example: Find Max in a Set 🔹 Output: ✅ Explanation: .stream() – converts the Set to a … Continue reading →

👌 To display 10 random numbers in ascending order, you can: Generate 10 random numbers, Sort them using sorted(), Print them using forEach(). ✅ Example Using Random and Streams

✅ Goal: Use filter() to keep only empty strings. Use count() to get the number of them. 🔹 Example: 🔹 Output: ✅ Breakdown: filter(String::isEmpty): keeps only strings that are “” count(): returns the total number of elements remaining after filtering

✅ Goal: Square each number in a list. Remove duplicates (make them unique). Print them using forEach().

✅ Example using Stream.generate() 🔹 Breakdown: Stream.generate(…): creates an infinite stream random.nextInt(100): generates a random number between 0 and 99 limit(10): keeps only the first 10 forEach(…): prints them one by one

✅ Common Intermediate Stream Methods Here’s a full list of the most important ones grouped by purpose: 🔹 1. Transformation Method Description map() Transforms each element flatMap() Flattens nested streams mapToInt(), mapToDouble(), mapToLong() Special for primitives

🔹 1. Collecting Results Method Description collect() Accumulates elements into a collection (like List, Set, Map) toArray() Converts the stream into an array Example:
