Senior java developer Interview Questions

Suggestion - Give only 10-15 minutes for the MCQs then you can easily do remaining SQL & Java code questions easily in remaining time.

Anyone looking for the exact code then leave the message.

Answers of both these questions are over internet & here on Glassdoor.

let string:String = "AAAAABBBVVVCVCAA" let characters = Array(string) var counter:Int = 1 var newArray:[String] = [String]() let lastCount = characters.count - 1 for count in 0...(characters.count - 2) { if characters[count] == characters[count + 1] { counter = counter + 1; }else { newArray.append("\(counter)\(characters[count])") counter = 1 } if lastCount == count + 1 { newArray.append("\(counter)\(characters[count])") } } print(newArray)

public static void main(String[] args) { String s = "AAAAAAAAAAAAAAAAAABBBBBBBBBBBBBBCC"; Set set = new HashSet(); char b = 0; int count = 1; String newString = ""; for (int i = 0; i 0) { b = s.charAt(i - 1); } char c = s.charAt(i); if (!set.add(c)) { count++; } else { if (b != 0) { newString = newString + b + count; count = 1; } } } newString = newString + b + count; System.out.println(newString); }

I said due to salary & work there. To this HCL manager says that I am a selfish person & because of my kind of people India is not getting good work. What a rubbish statement from a Manager.

Don't believe any positive negative reviews, just apply your logic, these HCL like companies hire cheap, third class managers to exploit other employees. And these companies manipulate the reviews on Glassdoor also.

spring, hibernate, rest jsp and servlet and threading. prepare each module of spring in detail. Thread synchronization and all the possible scenario on the same, all the basic keywords of java, string programs, for loop programs and what not basically u need to be good at everything to clear deloitte

Inner class- it is used for nested class, it can have all the access of outer class and can have access to private method as well. It can have any type of modifier defined.

what kind of program they ask?

plz tell me what kinf of program they ask?

No Multiple inheritance is not permitted in java. This is to avoid the diamond problem

Yes, java supports multiple inheritances where a class can inherit properties of more than one parent class.

int val = 1; for(int i = 1; i <= n; i++) { for(int j = 0; j < i; j++) { System.out.print(val + " "); val++; } System.out.println(); }

Python code for the same: def pattern(n): num = 0 for i in range(1,n+1): for j in range(i): num += 1 print(num, end=' ') print() pattern(4)
