Create a java program in array that find the duplicate values in an array
In this video, I will demonstrate and explain each line of code used to solve a common Java programming problem: finding duplicate values in an array.
📌 Problem Statement:
Create a Java program that identifies duplicate values in an array and displays their indexes.
✅ Example Input: {1, 2, 3, 1, 2, 4, 1}
✅ Expected Output:
Duplicate value found
value 1 at index 0, 3, 6
value 2 at index 1, 4
📖 Topics Covered:
✔️ Java Arrays
✔️ Iterating through arrays
✔️ Using HashMaps for frequency counting
✔️ Printing formatted output
💻 Code Walkthrough:
I go through each line of the code, explaining how it works and why it’s written that way, so you can easily understand the logic behind it.
