Write java statements that inputs two integers (n and k) entered by the user, generate n random double numbers in a range [0, 100], then calculate the followings: Sum of these numbers, Average of these numbers, • Average of their square roots, • Round these numbers to specified decimals k, find average of rounded numbers. One of the methods to round a double number to k decimal places is by using a DecimalFormat object and format method: import java.text.DecimalFormat; String formatStr = "#. ###"; DecimalFormat df = new DecimalFormat (formatStr); double rounded_number = Double.valueOf (df.format (random_number)); // round 3 decimal places If you use this method, before generating numbers, you must create appropriate formatStr by appending k times "#" to the end of "#.", and then create the DecimalFormat object.

Question
Can you write java code according to the conditions ?
![Write java statements that inputs two integers (n and k) entered by the user, generate n random
double numbers in a range [0, 100], then calculate the followings:
• Sum of these numbers,
Average of these numbers,
Average of their square roots,
• Round these numbers to specified decimals k, find average of rounded numbers.
One of the methods to round a double number to k decimal places is by using a DecimalFormat object
and format method:
import java.text.DecimalFormat;
String formatStr = "#.###";
DecimalFormat df = new DecimalFormat (formatStr);
double rounded_number = Double.valueof (df.format (random_number) );
// round 3 decimal places
If you use this method, before generating numbers, you must create appropriate formatStr by
appending k times "#" to the end of "#.", and then create the DecimalFormat object. Then in the loop,
you can use the last line above to obtain rounded number from randomly generated number.
