Simple Java project themes based on your Step 1: Java Basics – The Foundation

 Here are some simple Java project themes based on your Step 1: Java Basics – The Foundation, without using OOP, Collections, Exception Handling, or File Handling. These projects rely purely on core syntax, arrays, strings, loops, and conditions.

🔹 1. Number Guessing Game

  • User guesses a number generated by the program.

  • Uses if-else, loops, random number generation, and input handling.

🔹 2. Simple Calculator

  • Performs operations: +, -, *, /, %.

  • Uses switch-case and operators.

🔹 3. Grade Calculator

  • User enters marks for 5 subjects.

  • Calculates average and assigns grade using if-else.

🔹 4. Palindrome Checker

  • Checks if a string is the same forwards and backwards.

  • Uses strings, loops, and conditions.

🔹 5. Vowel and Consonant Counter

  • Takes a string input and counts vowels and consonants.

🔹 6. Even or Odd Number Finder

  • Takes a number and checks if it’s even or odd using %.

🔹 7. Multiplication Table Generator

  • User enters a number, program prints its multiplication table using for loop.

🔹 8. Prime Number Checker

  • User enters a number, program checks if it is prime using loops.

🔹 9. Array Sorting (Bubble Sort)

  • Takes an array of numbers and sorts them in ascending order.

🔹 10. Frequency of Elements in an Array
