Java 8 introduces several new language features designed to make it easier to write such blocks of code-the key feature being lambda expressions, also colloquially referred to as closures or anonymous methods. A lambda expression is just a shorter way of writing an implementation of a method for later execution.
1. Write a Java program to implement a lambda expression to find the sum of two integers.
2. Write a Java program to implement a lambda expression to check if a given string is empty.
3. Write a Java program to implement a lambda expression to convert a list of strings to uppercase and lowercase.
4. Write a Java program to implement a lambda expression to filter out even and odd numbers from a list of integers.
5. Write a Java program to implement a lambda expression to sort a list of strings in alphabetical order.
6. Write a Java program to implement a lambda expression to find the average of a list of doubles.
7. Write a Java program to implement a lambda expression to remove duplicates from a list of integers.
8. Write a lambda expression to implement a lambda expression to calculate the factorial of a given number.
9. Write a Java program to implement a lambda expression to create a lambda expression to check if a number is prime.
10. Write a Java program to implement a lambda expression to concatenate two strings.
11. Write a Java program to implement a lambda expression to find the maximum and minimum values in a list of integers.
12. Write a Java program to create a lambda expression to multiply and sum all elements in a list of integers.
13. Write a Java program to implement a lambda expression to count words in a sentence.
14. Write a Java program to implement a lambda expression to check if a given string is a palindrome.
15. Write a Java program to implement a lambda expression to calculate the sum of squares of all odd and even numbers in a list.
16. Write a Java program to implement a lambda expression to check if a list of strings contains a specific word.
17. Write a Java program to implement a lambda expression to find the length of the longest and smallest string in a list.
18. Write a Java program to implement a lambda expression to check if a given number is a perfect square.
19. Write a Java program to implement a lambda expression to find the second largest and smallest element in an array.
20. Write a Java program to implement a lambda expression to sort a list of objects based on a specific attribute.
21. Write a Java program to implement a lambda expression to calculate the sum of all prime numbers in a given range.
22. Write a Java program to implement a lambda expression to check if a list of strings are all uppercase or all lowercase or mixedcase.
23. Write a Java program to implement a lambda expression to find the average length of strings in a list.
24. Write a Java program to implement a lambda expression to find the largest prime factor of a given number.
25. Write a Java program to implement a lambda expression to convert an integer to their corresponding binary representation.
