Java Coding Programs

 

1. Reverse a String:
Write a Java program to reverse a given string.

2. Find the Largest Element in an Array:
Find and print the largest element in an array.

3. Check for Palindrome:
Determine if a given string is a palindrome (reads the same backward as forward).

4. Factorial Calculation:
Write a function to calculate the factorial of a number.

5. Fibonacci Series:
Generate the first n numbers in the Fibonacci sequence.

6. Check for Prime Number:
Write a program to check if a given number is prime.

7. String Anagrams:
Determine if two strings are anagrams of each other.

8. Array Sorting:
Implement sorting algorithms like bubble sort, merge sort, or quicksort.

9. Binary Search:
Implement a binary search algorithm to find an element in a sorted array.

10. Duplicate Elements in an Array:
Find and print duplicate elements in an array.

11. Linked List Reversal:
Reverse a singly-linked list.

12. Matrix Operations:
Perform matrix operations like addition, multiplication, or transpose.

13. Implement a Stack:
Create a stack data structure and implement basic operations (push, pop).

14. Implement a Queue:
Create a queue data structure and implement basic operations (enqueue, dequeue).

15. Inheritance and Polymorphism:
Implement a class hierarchy with inheritance and demonstrate polymorphism.

16. Exception Handling:
Write code that demonstrates the use of try-catch blocks to handle exceptions.

17. File I/O:
Read from and write to a file using Java's file I/O capabilities.

18. Multithreading:
Create a simple multi threaded program and demonstrate thread synchronization.

19. Lambda Expressions:
Use lambda expressions to implement functional interfaces.

20. Recursive Algorithms:
Solve a problem using recursion, such as computing the factorial or Fibonacci sequence.
