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.
