Assume that the SampleQueue class, with the given code below, is used in the TestSampleQueue that is also shown below. Show the output of the TestSampleQueue. Do the exercise without using a computer (i.e. Make amanual trace of the program):// SampleQueue classimport java.lang.*;import java.util.*;public class SampleQueue<T> {private LinkedList<T> list;public SampleQueue() {list = new LinkedList<T>();}public void setList(LinkedList<T> list) {this.list = list;}public void clear() {list.clear();}public boolean isEmpty() {return list.isEmpty();}public T firsElement() {return list.getFirst();}public T dequeue() {return list.removeFirst();}public void enqueue(T element) {list.addLast(element);}public LinkedList<T> getList() {return list;}public String toString() {return list.toString();}} // end of SampleQueue class
: Imagine you are reading in a stream of integers. Periodically, you wish to be able to look up the rank of a number x (the number of values less than or equal to x). Implement the data structures and algorithms to support these operations. That is, implement the method track(int x), which is called when each number is generated, and the method getRankOfNumber(int x), which returns the number of values less than or equal to x (not including x itself). EXAMPLE Stream (in order of appearance): 5, 1, 4, 4, 5, 9, 7, 13, 3 getRank Of Number (1) = 0 getRankOf Number (3) = 1 getRankOfNumber (4) = 3
Use for loop in Java language Write the method stringSplosion().* * The method takes one parameter, a non-empty String str (such as "Code") and* returns a String in the form "CCoCodCode". Notice that this includes the* first character of the original String, followed by the first two characters,* and so on until the whole String is used.* * Examples: stringSplosion("Code") returns "CCoCodCode" stringSplosion("abc")* returns "aababc" stringSplosion("x") returns "x"* * @param str the input String to process.* @return a new String as described above.
