💥Find Second Largest(Maximum) in Array ☕Java Interview Programs👨‍🎓Campus Interview Programs 🎁👩‍🏫Java

🎯 Java Program – Find Second Maximum Element in Array Welcome to our channel 🙏 In this video, we learn how to find the Second Largest (Second Maximum) element in an Array using Java. This is a very popular Java interview program and helps beginners clearly understand: ✅ Array traversal ✅ Comparison logic ✅ Using two variables (first and second) ✅ Finding second largest in a single loop This program is very useful for: ✔ Freshers ✔ College students ✔ Java beginners ✔ Campus placements Please watch till the end and practice on your own laptop. 🧠 What is Second Maximum? Second Maximum means: 👉 The second biggest number in the array. Example: Array: 2, 1, 4, 3, 9, 7, 8, 0, 10 Largest = 10 Second Largest = 9 🧠 Variables Used arr → array elements first → stores largest value second → stores second largest value i → loop counter ✅ Logic Explanation Step by Step Step 1 – Declare array int[] arr = {2,1,4,3,9,7,8,0,10}; Step 2 – Initialize variables int first = 0; int second = 0; first holds maximum second holds second maximum Step 3 – Loop through array for(int i=0; i is less than arr.length; i++) Loop checks every element. Step 4 – Compare with first (largest) if(arr[i] is greater than first) Then: second = first; first = arr[i]; Meaning: Old largest moves to second New value becomes largest Step 5 – Compare with second else if(arr[i] is greater than second) Then: second = arr[i]; This handles values between first and second. 🧪 Dry Run Array: 2, 1, 4, 3, 9, 7, 8, 0, 10 Start: first = 0 second = 0 Process: 2 → first becomes 2 1 → second becomes 1 4 → second becomes 2, first becomes 4 3 → second becomes 3 9 → second becomes 4, first becomes 9 7 → second becomes 7 8 → second becomes 8 0 → no change 10 → second becomes 9, first becomes 10 Final: first = 10 second = 9 Step 6 – Print result System.out.println(second); Output: 9 ⭐ Why Interviewers Ask This? Tests: ✔ Array traversal ✔ Nested comparison ✔ Logical thinking ✔ Optimized single loop ⚠ Common Mistakes ❌ Forgetting to update second before first ❌ Using sorting instead of logic ❌ Initializing wrongly ❌ Missing else condition second largest in array java find second maximum java java array interview programs second highest number java java logical programs #Java #ArrayPrograms #SecondLargest #JavaInterview #ProgrammingTamil #Freshers #CampusPlacement
