MuhammedSaheerPS/Java-Logical-Programs

This repository contains a comprehensive collection of Java-based logical programs that demonstrate my ability to solve problems using clear, efficient, and structured programming techniques. Each file solves a unique task using core Java principles such as loops, conditionals, arrays, strings, and user input.

These programs were created as a demonstration of:

• My knowledge of Java fundamentals
• Logical thinking and step-by-step problem-solving
• Preparation for coding interviews and academic assessments
• Building a strong base in algorithmic programming

• Armstrongnum.java – Check for Armstrong numbers
• Leapyear.java – Determine leap years
• Fibonacci.java – Generate Fibonacci series
• PrimeNumber.java – Check for prime numbers
• Simpleinterest.java – Calculate simple interest
• Numtowords.java – Convert numbers to words

• Palindrome.java – Check if a string is a palindrome
• Removevowel.java – Remove vowels from input
• VowandCons.java – Count vowels and consonants
• Wordreverseprint.java – Reverse each word in a sentence
• Stringtochar.java – Convert string to character array

• array.java – Array basics
• Largestandseclargest.java – Find two largest elements
• Reverseingarr.java – Reverse an array
• Movezero.java – Move all zeros to end
• Ascending.java – Sort array in ascending order

• BinarySearchProg.java – Binary search algorithm
• Occurance.java – Frequency of elements
• Nonrepeating.java – Identify non-repeating characters
• NumberOfOccurance.java – Count number of occurrences

• Login.java – Simulate a login system
• Ebbilling.java – Electricity billing calculator
• Swap.java – Swap two numbers
• Splitdigit.java – Split number into digits
• Tables.java – Generate multiplication tables

• Java (JDK 8 or above)
