Answer:
Below is java code that must be used for the given question:
// highArray.java
// demonstrates array class with high-level interface
// to run this program: C>java HighArrayApp
////////////////////////////////////////////////////////////////
class HighArray
{
private long[] a; // ref to array a
private int nElems; // number of data items
//-----------------------------------------------------------
public HighArray(int max) // constructor
{

nElems = 0; // no items yet
}
//-----------------------------------------------------------
public setValue find(long searchKey)
{ // find specified value
int j;
for(j=0; j<nElems; j++) // for each element,
if(a[j] == searchKey) // found item?
break; // exit loop before end
if(j == nElems) // gone to end?
return false; // yes, can't find it
else
return true; // no, found it
} // end find()
//-----------------------------------------------------------
public void insert(long value) // put element into array
{
a[nElems] = value; // insert it

}
//-----------------------------------------------------------
public void display() // displays array contents
{
