Answer:
An online company wants to conduct real-time sentiment analysis about its products from its social media channels using SQL. The solution which has lowest cost and operational burden is as follow:
B. Configure the input stream using Amazon Kinesis Data Streams. Use Amazon Kinesis Data Analytics to write SQL queries against the stream.
Explanation:
- The option A is not correct as this solution doesn't have lowest cost and operational burden as set up a streaming data ingestion application on Amazon EC2 and connect it to a Hadoop cluster for data processing will have more cost and operational burden.
- The lowest cost and operational burden solution is that we configure input stream using Amazon Kinesis Data Streams. We can use Amazon Kinesis Data Analytics to write SQL queries against the stream.
- The option c and d are also more pricey in terms of cost and operational burden as compared to Amazon Kinesis Data stream and analytics.
Answer:
int age = 10;
switch (age){
case 0:
case 1:
System.out.println("ineligible");
break;
case 2:
System.out.println("toddler");
break;
case 3:
case 4:
case 5:
System.out.println("early childhood");
break;
case 6:
case 7:
System.out.println("young reader");
break;
case 8:
case 9:
case 10:
System.out.println("elementary");
break;
case 11:
case 12:
System.out.println("middle");
break;
case 13:
System.out.println("impossible");
break;
case 14:
case 15:
case 16:
System.out.println("high school");
break;
case 17:
case 18:
System.out.println("scholar");
break;
default:
System.out.println("ineligible");
}
Explanation:
In java and many other programming languages, a switch statement is a way of having multiple branching options in a program. This is usually considered a more efficient way than using multiple if....else if statements. and the expression variables could be byte, char int primitive data types. etc. every branch (option) in a switch statement is followed by the break statement to prevent the code from "falling through". In the question The variable age is declared as an int and initialized to 10. and tested against the conditions given in the question.
you can install a 64 bit operating system on a 32 bit machine.
hope this helps!
