Vector based heap in java

Can anyone help me to complete my following program??

im****t java.util.vector;

class Heap{
        Vector data;
        void insert(Object obj) {
              int loc=data.size();
              data.addatLastLoc(obj);

   while(loc != 0){
        int parent = floor((loc-1)/2);
        Object par = data.getIthElement(parent);
       if(par.compareTo(obj)<=0) break;

       Object temp = par;
       data.replaceIthElement(parent,obj);
       data.replaceIthElement(loc,temp);
       loc = parent;
      obj= data.getIthElement(loc);
}

Object removeMin(){
       int loc = data.size()-1;
        swap(root && loc objects)
        int curr =0;
        int leftchild=curr*2+1;
        int rightchild = curr*2+2;
