Q2.  Create a Sim Class with following Attributes
int simId;
String customerName;
double balance;
double ratePerSecond;
String circle;

Create a public Class Solution in which take input of 5 object and then take 2 input (circle1, circle2) for circle of matches as circle1 and choose only those objects which are match with circle1.

Create a method named as transferCircle() and passed sim object and circle1, circle2 as parameter and arrange sim object in descending order as per ratePerSecond
Print the output as simId, customerName, circle, ratePerSecond.

​

Input:
1
