1. **Binary Search**
44+
- **Problem:** Implement a binary search algorithm to find the position of a
45+
target value within a sorted array.
46+
- **Link:** [View Code](https://github.com/jdevstatic/java-coding-problems/blob/main/src/BinarySearch.java)
47+
- **Discussion:** Binary search is an efficient algorithm for finding an item
48+
from a sorted list of items. It works by repeatedly dividing in half the
49+
portion of the list that could contain the item, until you've narrowed down
50+
the possible locations to just one.
51+
52+
2. **Checking Palindrome**
53+
- **Problem:** Check if a given string is a palindrome.
54+
- **Link:** [View Code](https://github.com/jdevstatic/java-coding-problems/blob/main/src/CheckPalindromeString.java)
55+
- **Discussion:** A palindrome is a word, phrase, number, or other sequence
56+
of characters that reads the same forward and backward (ignoring spaces,
57+
punctuation, and capitalization). The algorithm typically involves
58+
comparing characters from the beginning and end of the string moving
59+
towards the center.
60+
61+
3. **Inheritance**
62+
- **Problem:** Demonstrate the concept of inheritance in Java.
63+
- **Link:** [View Code](https://github.com/jdevstatic/java-coding-problems/tree/main/src/inheritance)
64+
- **Discussion:** Inheritance is a fundamental concept in object-oriented
65+
programming where a new class is created from an existing class. The new
66+
class (subclass) inherits attributes and methods from the existing class
67+
(superclass), allowing for code reuse and the creation of a hierarchical
68+
relationship between classes.
69+
70+
4. **Integer Array Sum**
71+
- **Problem:** Calculate the sum of all integers in an array.
72+
- **Link:** [View Code](https://github.com/jdevstatic/java-coding-problems/blob/main/src/IntegerArraySum.java)
73+
- **Discussion:** This problem involves iterating through an array of
74+
integers and accumulating the sum of its elements. It is a straightforward
75+
problem that demonstrates basic array manipulation and iteration.
76+
77+
5. **Merge Sort**
78+
- **Problem:** Implement the merge sort algorithm.
79+
- **Link:** [View Code](https://github.com/jdevstatic/java-coding-problems/blob/main/src/MergeSort.java)
80+
- **Discussion:** Merge sort is a divide-and-conquer algorithm that divides
81+
the input array into two halves, recursively sorts them, and then merges
82+
the sorted halves. It is known for its efficiency and stable sorting
83+
properties.
84+
85+
6. **Prime Number Checker**
86+
- **Problem:** Check if a given number is a prime number.
87+
- **Link:** [View Code](https://github.com/jdevstatic/java-coding-problems/blob/main/src/PrimeNumberCheck.java)
88+
- **Discussion:** A prime number is a natural number greater than 1 that has
89+
no positive divisors other than 1 and itself. The algorithm typically
90+
involves checking divisibility from 2 up to the square root of the number.
91+
92+
7. **Fibonacci Series**
93+
- **Problem:** Print the Fibonacci series up to a given number.
94+
- **Link:** [View Code](https://github.com/jdevstatic/java-coding-problems/blob/main/src/PrintFibonacciSeries.java)
95+
- **Discussion:** The Fibonacci series is a sequence where each number is the
96+
sum of the two preceding ones, usually starting with 0 and 1. This problem
97+
can be solved using iterative or recursive approaches.
98+
99+
8. **Remove A Character**
100+
- **Problem:** Remove all occurrences of a given character from a string.
101+
- **Link:** [View Code](https://github.com/jdevstatic/java-coding-problems/blob/main/src/RemoveAChar.java)
102+
- **Discussion:** This problem involves iterating through the string and
103+
building a new string that excludes the specified character. It
104+
demonstrates string manipulation techniques.
105+
106+
9. **Remove Whitespaces**
107+
- **Problem:** Remove all whitespaces from a string.
108+
- **Link:** [View Code](https://github.com/jdevstatic/java-coding-problems/blob/main/src/RemoveWhiteSpaces.java)
109+
- **Discussion:** This problem involves iterating through the string and
110+
building a new string that excludes all whitespace characters. It is a
111+
common string manipulation task.
112+
113+
10. **Reverse A Linked List**
114+
- **Problem:** Reverse a singly linked list.
115+
- **Link:** [View Code](https://github.com/jdevstatic/java-coding-problems/blob/main/src/ReverseALinkedList.java)
116+
- **Discussion:** Reversing a linked list involves changing the direction of
117+
the pointers in the list. This problem is a classic example of pointer
118+
manipulation in data structures.
119+
120+
11. **Reverse A String**
121+
- **Problem:** Reverse a given string.
122+
- **Link:** [View Code](https://github.com/jdevstatic/java-coding-problems/blob/main/src/ReverseString.java)
123+
- **Discussion:** Reversing a string involves swapping characters from the
124+
beginning and end of the string moving towards the center. It is a basic
125+
string manipulation problem.
126+
127+
12. **Shuffle Array**
128+
- **Problem:** Shuffle the elements of an array randomly.
129+
- **Link:** [View Code](https://github.com/jdevstatic/java-coding-problems/blob/main/src/ShuffleArray.java)
130+
- **Discussion:** Shuffling an array involves randomly permuting its
131+
elements. This can be achieved using algorithms like the Fisher-Yates
132+
shuffle.
133+
134+
13. **Sort Array**
135+
- **Problem:** Sort an array of integers.
136+
- **Link:** [View Code](https://github.com/jdevstatic/java-coding-problems/blob/main/src/SortArray.java)
137+
- **Discussion:** Sorting an array involves arranging its elements in a
138+
specific order (ascending or descending). Various algorithms can be used,
139+
such as quicksort, mergesort, or bubble sort.
140+
141+
14. **Check Vowels**
142+
- **Problem:** Check if a string contains any vowels.
143+
- **Link:** [View Code](https://github.com/jdevstatic/java-coding-problems/blob/main/src/StringContainsVowels.java)
144+
- **Discussion:** This problem involves iterating through the string and
145+
checking for the presence of vowel characters (a, e, i, o, u). It
146+
demonstrates basic string traversal and condition checking.
