Java Tutorial: Practice Questions on Arrays in Java

// Question 7 - Finding out the minimum element of Array int[] arr2 = {-1, -4, 53, -32, -6, 92, 10, -372}; int min = Integer.MAX_VALUE; for (int elem: arr2) { if (elem < min) { min = elem; } } System.out.println(min);

Thanks

or you can keep the int min = arr2[0]; that also works.

This is actually funn, Watching this video at 2 AM, Understanding something new in the silence of night, I watched your 2D array video 4 times before moving ahead and it turns out that i understood array but was having difficulty with understanding nested loops, i needed to watch some other videos about nested loops to understand them, i am not complaining about that, this playlist is awesome, a single person cannot handle everything so perfectly but you still made it perfect!! Thankyou for this amazing Playlist and listing it on the internet for free, You are not teaching a youtube user, you are shaping the Indian future!

[@vkumar1066]

Clearing the doubts in Q5 . Many people had this confusion.. For reversing the array. brother you have to reverse the array. Not just u have to print the values in reverse. think on it once. Earlier I also used to think the same way. But got cleared. In the method explained by harry bhai he is trying to reverse the actual array and that is what the question is about. The question is not to print the array in reverse order.

Use two array that's similar to your process , just store the values in reverse order of one into other and equate them later

29:03 instead of going through broader way ,we can reverse an array by this way int [] arr = {1,2,3,4,5,6,7,8,9}; int l = arr.length; for(int i=l-1;i>=0;i--) { System.out.print(arr[i] +" "); } above program i think is simplest way to reverse an array

But here the problem is that you have just printed the array in reverse order...and not actually reversed it...like by that logic used in the video,you are actually changing the value stored at the i th address with the value stored at( l-i-1)th address..and in whole reversing the array

Sir, it's getting complex. Difficult to understand 😭

in 2d array

[@rohananand8253]

Yes then watch again this video

[@salmanmehmood180]

this is replacement of answer 5 int [] rev={6,5,4,3,12,1}; for (int i=rev.length-1;i>=0;i--){ System.out.println(rev[i]); }

[@gametimewitharyan6665]

To understand it better, just first listen the question and then try to solve it by yourself, and if you are not able to solve then watch the solution for answer and understanding

for practice problem 2 (without using for each loop and boolean) :- int [ ] nm = {8,9,10}; for (int i =0; i

Bole to mja aa gya 🤟🤩 thanku harry bhaiya

[@suprabhatnandi8598]

Hi,Just want to know by when you will complete this java playlist,just a rough estimate.

Concepts Pura clear ho gaya Harry Bhaiya maja hi aagaya ekdam.

[@shantanupanditiitdelhi5515]

Maja aa gaya , Harry Bhai !!

[@mightyprogrammer2899]

harry bhai question no 5 practice problem no. 5 // to reverse an array element what a lesson yrr superb idk how to thanks Thank you so much.

[@ramphapal6610]

Maja Aa gaya😊 bohat hi Aachhye the problem,, or bohat kuch sikhane ko mila,, thanks harry bro❤

[@faizanjan102]

46:24 we can also use ---------------------------------- for (int i=1; i h[i]){ isSorted = false; break; } }

[@ytuser0101]

can you tell me why in second loop -1 was used (int i=0; i

[@hameedferoz8804]

Sabse Best Practice Set tha ye. Thank you Harry Bhai

[@ashutosh5406]

maza aa raha h harry bhai... thank you so much bro. you're doing great work for our country.

[@biggestcomeback-w8x]

everything is temporary but "right click karke run karna hai" is permananent" and also thanks for your videos .i am currently studying in class 10 and your videos helped me a lot(till video no 66.) in my boards... batch 2024-2025.......love from bihar....

[@NoobCoder623]

Best video on all concepts of array at beginners level. Best explanation.May god bless you for giving us this course ❤️❤️.

[@chetnabansal370]

Needless to say that videos are full of new concepts and fun. Earlier I thought, in order to reverse the array we could just start iteration from arr.length till 0 but it didn't work (of course, how stupid was I !). Idk if you will ever read my comment or not but I literally want you to say a big THANK YOU !!

[@randomx7629]

try arr.length-1 till 0...coz last index is not equal to arr.length

[@miracleatom8680]

Sachii Amazing lectures Good Job MashaAllaha !!!!!!!

[@chetanranghani9695]

int [] arr = {5, 2100, 3, 455, 5, 34, 67}; int min = Integer.MAX_VALUE; for(int e: arr){ if(e

[@abhinavrawat2048]

man you are too good when it comes to explaining things...thank you so much

[@maytan1475]

24:33 to reverse a string : public class demo { public static void main(String[] args) { int[] array= {1,2,3,4,5,6}; for(int i =array.length-1;i>0;i--) { System.out.print(array[i]+" "); } } }

[@abdulwahabkaladgi2027]

public class Arrays { public static void main(String[] args) { String [] months = {"January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"}; for (int i=months.length-1; i>=0; i--){ System.out.println(months[i]); } } } this one executed perfectly

[@AnimeFusionHub25]

41:40 we can also find min value like this public static void main(String[] args) { int []arr = {1,2,3,4,34,-3,68,22}; int max = 0,min=0; for(int i=0;i

[@faizan_moazim_123]

21:17 Practice Problem 5 simple way // Practice Problem 5 int[] arr = {10,20,30,40}; // arr.length -1 = length ko minus karo and print kro or reverse array found for(int i = arr.length -1; i >= 0; i--){ System.out.print(arr[i] + " "); }
