This overview of basic terms at 3:01 is very useful for beginners like me!

Please maam, only one program code write at a time, some code line of previous program are present in present program code and also more coment line so that program code so long and we are not able to see all code line at a time on screen so that we couldn't understood programprogram.
I request to you maam, you try to write all code line which see at a time on screen 🙏🙏🙏

[pawanrajput]

Thank you so much ma'am ❤️
For more lecture of arrays
Please ma'am continue

[Aditya-ftlz]

Mam please we want a complete your college journey video how you start your coading journey and how you manage your college also....please mam its help us alot to motivate in our journey 🙏😊

[bluelegend]

It' too much easy to learn Java with mam🥳

[handledByHandle]

to rotate array without using space:
static int [] reverseArray(int [] arr){
int j = arr.length - 1;
int n = 5;
n = n % arr.length;
while(n > 0) {
for (int i = 0; i < arr.length; i++) {
int temp = arr[i];
arr[i] = arr[j];
arr[j] = temp;
}
n--;
}
return arr;

}
thank you :)

[bharagava]

examples are explained very well ...❤‍🔥

[kunalpatidar]

for swaping we have 4 popular logics
int a=12;
int b=10;

//first logic
int temp=b;
b=a;
a=temp;

//2nd logic
a=a+b;
b=a-b;
a=a-b;

//3rd logic this logic not work properly if any value is 0;
a=a*b;
b=a/b;
a=a/b;

//4th logic
a=a^b;
b=a^b;
a=a^b;

Unable to access notes and assignment page. It is showing error saying that Page not found. Please look towards this concern manvi ma'am.
And at last, Both of you Raghav Sir and Manvi Ma'am are one of the best educator. Doing great job.

Why my queston 5 Rotate the array with k steps without extra spaces, is not working in VS Code. I haev checked my code many times it is right but the code is not rotating the array at all in the output.

Physics wallah series बहुत बढ़िया हे मेने रात भर जाग जाग कर पूरे, सभी episodes देखे
And thank you for caring students

[PrabhatSharma-zlff]

YOU WRITE MANY CODE ON SINGLE SCREEN SO THIS IS VERY DIFFICULT TO UNDERSTANT THIS LECTURE IS VERY HARD TO UNDERSTAND

[KrishnaNayak-ohlj]

50:25 wala code me last line printArray error de Raha hai😢
