1. Complete the body of this method. Use a ChaQueue to store the input line as it is being read. The parameter is an EasyReader from Appendix B of the text. Use the method in charlnput) to read and return the nexi character of the EasyReader, and use in.isEOLN) to detemine whether he ext input character is the end-of-line. public static int counter (EasyReader in) // Precondition : There is line af nput waiting to be read from in Postcondition: A ine of input has heen read fron in, up to tut not includine the newiine character. The return value of the nethad is the number of times that the LAST character of the 1ine appeared somewhere in this line XAPLE Input: ABExDxxzx The value returned by counter would be 4 for this input sinc- there are 4 X's in the input lino 2. I am going to execute this code ith THREE inserts and ONE get front: IntQueue qne IntQueue; q.insert(1) q.insert(2); q.insert(3); Systen.out-println q-BotFront; Suppose that q is represented by a circular array. Draw the state of these private instance variables ofter the above code: data 3. I amgoing to execute this code with THREE insert and ONE get front: IntQueue q new IntQueue( ); q.insert(1): q.insert(2); q.insert(3); Systen.out printlniq.BetFront); Suppose that q is represented by a linked list.
