for(int i=a.length-1;i>=0;i--) {
System.out.println(a[i]);
} you can give like this also simple method to reverse array

[@BTechComputerScience]

Hey there, this is also a good solution, but here all u can do is print in reverse order. Many interviewers won't accept this... they ll ask for an array which has reversed elements of the original array, which can be used for any other operation if needed. For example if the question says - reverse the array and find the index of the largest/smallest number in it.
Hence leaning to create a reversed array is also important. 😊

[@pranavdeshpande3676]

Worked!! I wondered after watching the video that how will it work for odd number of elements in array, but later realized that it does and why it does. Thanks for the video.

[@pravarkunnath3519]

Why does it work with odd array?

[@pranavdeshpande3676]

@@pravarkunnath3519 In odd array there will be left a middle element right!
We don't have to touch it, it will stay at its position only even after reversing.
Hence It works
Hope it helps
Enjoy coding

Very helpful Thank you boss

thanks bro..i could not understand swapping part

Bro what if it's not arranged in ascending or descending order ?

[@BTechComputerScience]

It doesn't matter, it ll work😊

Please explain" reverse string"

[@sarankarthic5772]

This code doesn't work if there are duplicates in array

[@happyteen7195]

it works

[@HNTAutumnleaf]

Nice video! But can you do it in recursive?😁

[@BTechComputerScience]

I should give it a try 🤔

[@Jobupdates29]

thank you

[@aasimkhan271]

why using j=a.lenght-1 ??

[@prathameshshaniware2377]

Because the index of the array starts form 0, to access last index of the array you have to set array.lenght - 1.

Uspe tum 5 bhi likh sakte ho

[@harishkumarreddy1999]

@@kartikpaul3161what if you don’t know the length of an array?

[@naveenkumar6768]

a.length - it is used to find the length of one particular array, here the array name is a, so we put a.length and the reason for a.length-1 is simple we just need the index to its common to do -1 with the length of that particular array, hope it's useful

[@thakursclub6432]

Because the length of the array is 6 but the last index is 5 . So we did length-1

Why in last array.tostring ?

[@mafia53042]

it is a predefined method that shows arrays in a string format
and similarly for 2d arrays we use arrays.deepToString method for output

[@yesitsme5948]

Error vasthundhi bro
Last lo sop lo (array.to string (a));. ???

[@BTechComputerScience]

Arrays.toString(a)

[@Notfound.5019]

you need to import import java.util.Arrays;
