Answer:

DecimalFormat form1= new DecimalFormat ("0.####");  // create an instance of                                                                                            .                                                                                            //DecimalFormat

System.out.println (form1.format(res)); // display the value in proper format

Explanation:

Following are the description of the program

  • Firstly we create the instance of DecimalFormat i.e  "form1"  that will round a formatted value to four decimal places. To create an instance or object of the class we can use a new keyword.
  • Finally, we print the format by using the format method.In the format method, we pass the variable "res".The System.out.println() is used to display the value of the format.

. Reorder the following efficiencies from smallest to largest:
alexdok [17]

Answer:

The order of the efficiencies is as following:-

10,000 < 2n < nlog(n) < n5 < n!.

Explanation:

10,000 is constant time whatever will be the size of the problem the efficiency will remain the same.

2n this efficiency is linear it will grow proportionally as the size of the problem increases.

nlog(n) this efficiency is is a bit greater than 2n though it will grow faster than 2n but slower than n2 as the size of the problem increases.

n5 this efficiency is very poor.It is growing very rapidly as the size of the problem increases.

n! is the worst efficiency of them all.

n!=n*(n-1)*(n-2)*(n-3)*(n-4)*.......2*1.

It will grow beanstalk in jack and the beanstalk.
