i keep getting the following error. it says it's found an int, but the heap is made up of Comparables, so i don't get it.

WorstFit.java:36: inconvertible types
found : int
required: java.lang.Comparable
if ((Comparable)(new Integer(s)).compareTo(myHeap.heap[1])<=0)



(the &quot;^&quot; is pointing at the &quot;(&quot; after &quot;compareTo&quot;)


here's the code, if it helps:

package dataStructures;
import java.util.*;

public class WorstFit
{

//s <= c for all i
public static void worstFitPack(int []s, int c)
{

//output packing information one by one


int j=1;

MaxHeap myHeap=new MaxHeap(s.length);

if (s[1]>c)
{
throw new IllegalArgumentException(&quot;an element in the array is bigger than the capacity of the containers&quot;);
}

myHeap.put((Comparable)(new Integer(s[1])));


for (int i=2; i<s.length; i++)
{

if (s>c)
{
throw new IllegalArgumentException(&quot;an element in the array is bigger than the capacity of the containers&quot;);
}



if ((Comparable)(new Integer(s)).compareTo(myHeap.heap[1])<=0)
{
Comparable previousAmount=myHeap.heap[1];
MyHeap.put((Comparable)((int)myHeap.removeMax())-((int)element));

System.out.println(+element[1] +&quot;is added to container with &quot; +previousAmount +&quot;. container now holds &quot; +myHeap.heap[1]);


}

else
{
myHeap.put((Comparable)(c-((int)(element))));

System.out.println(&quot;new container holds &quot; +element);

}

}
}


// test

public static void main(String []args)
{
int n = 10;

int c = 99;

int [] s = {0, 22, 84, 97, 47, 20, 64, 43, 11, 56, 96}; //s[0] is not used

WorstFit.worstFitPack(s, c);
}
}
 
nevermind. i put some more parentheses in and it works now
