Use the Heap class provided to implement a sort routine in a Main class where the user enters a series of values, each value is then pushed onto a heap, then the values are printed out in ascending order.public class Heap {    public static final int SIZE = 1025;        public Heap() {        elt = new Element[SIZE];        lastLoc = 0;    }        public void push(String k, Object o) {        if (!fullCheck()) {            lastLoc++;            elt[lastLoc] = new Element(k,o);            int loc = lastLoc;            while (loc > 1 && elt[loc].key.compareTo(elt[loc/2].key) < 0) {                Element hold = elt[loc];                elt[loc] = elt[loc/2];                elt[loc/2] = hold;                loc = loc/2;            }        }    }        public void pop() {        if (!emptyCheck()) {            elt[1] = elt[lastLoc];            lastLoc--;            int loc = 1;            while (2*loc <= lastLoc) {                loc = 2*loc;                if (loc < lastLoc && elt[loc +1].key.compareTo(elt[loc].key) < 0) loc=loc+1;                if (elt[loc].key.compareTo(elt[loc/2].key) < 0) {                    Element hold = elt[loc/2];                    elt[loc/2] = elt[loc];                    elt[loc] = hold;                }            }        }    }                public Object top() {        return elt[1].payload;    }    public Object topKey() {        return elt[1].key;    }    public boolean emptyCheck() {        return (lastLoc == 0);    }        public boolean fullCheck() {        return (lastLoc == SIZE-1);    }            private Element[] elt;    private int lastLoc;}
