Hi Naveen, You will always be one of the best teacher! The passion you have for technologies and what you teach is contagious! We always look forward to your videos - A big "Thank you!" . One request I had - Can you make a series/videos where you can tell us that what should an Automation Tester prepare and what all points we should follow so that we can also work in companies like Amazon, Oracle, Adobe, Walmart etc. Thanks in advance.

Hi naveen I was working as manual tester I started watching your classes started practicing simultaneously really I have seen many changes in me with in very less days heart full thanks for your support

Swapping numbers program might be asked without using any 3rd variable so below code works just by doing addition and subtraction

int a = 10;
int b = 20;
a = a + b; // 10+20 = 30 now a =30
b = a - b; // 30 - 20 = 10 now b = 10
a = a - b; // 30 - 10 = 20 now a = 20

Hi Naveen, the logic used for leap year will not work for years 1400, 1800
public class LeapYear {

public static void main(String[] args) {
int year=1400;
if((year%4==0) && ((year%400==0 || year%100!=0))) {
System.out.println(year+" is a leap year");
}else {
System.out.println(year+" is not a leap year");
}
}
}

[akshayrohankar]
