๐ŸŽฏ Java Program โ€“ Sum of Array Elements (Interview Program) Welcome to our channel ๐Ÿ™ In this video, we learn how to find the Sum of Array Elements in Java. This is one of the most common Java interview programs for freshers and beginners. Using this program, you will understand: โœ… What is an array โœ… How array indexing works โœ… What is array length โœ… How for-loop iterates array values โœ… How to calculate total using a temporary variable This program is very helpful for: โœ” College students โœ” Java beginners โœ” Freshers โœ” Campus placement preparation Please watch till the end and practice on your own laptop. ๐Ÿง  What is an Array? Array means: ๐Ÿ‘‰ Collection of multiple values stored in a single variable. Example: int[] arr = {60, 55, 70, 85, 75}; Here: 60 โ†’ index 0 55 โ†’ index 1 70 โ†’ index 2 85 โ†’ index 3 75 โ†’ index 4 Total elements = 5 That value is obtained using: arr.length ๐Ÿง  Variables Used arr โ†’ array values i โ†’ loop counter temp โ†’ stores sum โœ… Logic Explanation Step by Step Step 1 โ€“ Declare array int[] arr = {60,55,70,85,75}; Step 2 โ€“ Print array length System.out.println("length"+arr.length); Output: 5 Step 3 โ€“ Initialize sum variable int temp = 0; Step 4 โ€“ Loop through array for(int i=0; i is less than arr.length; i++) Loop runs 5 times (index 0 to 4) Step 5 โ€“ Add each element temp = temp + arr[i]; Process: temp = 0 + 60 temp = 60 + 55 temp = 115 + 70 temp = 185 + 85 temp = 270 + 75 Final temp = 345 Step 6 โ€“ Print result System.out.println("Sum of array elements"+temp); ๐Ÿงช Dry Run Array: 60, 55, 70, 85, 75 Sum: 60 + 55 + 70 + 85 + 75 = 345 Output: Sum of array elements 345 โญ Why Interviewers Ask This? Tests: โœ” Array basics โœ” Loop concept โœ” Index handling โœ” Accumulator variable โœ” Logical thinking โš  Common Mistakes โŒ Forgetting temp initialization โŒ Wrong loop condition โŒ Using fixed index instead of loop โŒ Confusing length with index java sum of array sum of array elements in java java array programs java interview programs array programs for freshers #Java #ArrayPrograms #SumOfArray #JavaInterview #ProgrammingTamil #Freshers #CampusPlacement
