Call the Generic parameterized method in java -

what error mesaage meant , how call generic parameterized method class: following error message:

the method add(int, integer) in type binaryminheap<integer> not applicable arguments (int, vertex<integer>) 

calling snippet:

 for(vertex<integer> vertex : graph.getallvertex()){                 minheap.add(integer.max_value, vertex);             } 

method being called is:

  public void add(int weight,t key) {             node node = new node();             node.weight = weight;             node.key = key;             allnodes.add(node);             int size = allnodes.size();             int current = size - 1;             int parentindex = (current - 1) / 2;             nodeposition.put(node.key, current);              while (parentindex >= 0) {                 node parentnode = allnodes.get(parentindex);                 node currentnode = allnodes.get(current);                 if (parentnode.weight > currentnode.weight) {                     swap(parentnode,currentnode);                     updatepositionmap(parentnode.key,currentnode.key,parentindex,current);                     current = parentindex;                     parentindex = (parentindex - 1) / 2;                 } else {                     break;                 }             }         } 

i'm not sure trying accomplish, cannot pass vertex<integer> takes integer. if want add every element of vertex, use nested loop. otherwise have map vexter<integer> integer somehow.

see method signature: binaryminheap<integer>.add(int, integer)

however, trying call vertex<integer> vertex that: add(int, vertex<integer>), not applicable (as stated in error)
