Need help with the last part of this java code! How would the last part of this code be written to display the duplicates?

class OrdArray { private long[] a; // ref to array a private int nElems; // number of data items //----------------------------------------------------------- public OrdArray(int max) // constructor { a = new long[max]; // create array nElems = 0; } //----------------------------------------------------------- public int size() { return nElems; } //----------------------------------------------------------- public long getValueAt(int index) { return a[index]; } //----------------------------------------------------------- public void setValueAt(int index, long value) { a[index] = value; } //----------------------------------------------------------- public int find(long searchKey) { int lowerBound = 0; int upperBound = nElems-1; int curIn;

while(true) { curIn = (lowerBound + upperBound ) / 2; if(a[curIn]==searchKey) return curIn; // found it else if(lowerBound > upperBound) return nElems; // can't find it else // divide range { if(a[curIn] < searchKey) lowerBound = curIn + 1; // it's in upper half else upperBound = curIn - 1; // it's in lower half } // end else divide range } // end while } // end find() //----------------------------------------------------------- public void insert(long value) // put element into array { int j; for(j=0; j value) // (linear search) break; for(int k=nElems; k>j; k--) // move bigger ones up a[k] = a[k-1]; a[j] = value; // insert it nElems++; // increment size } // end insert() //----------------------------------------------------------- public boolean delete(long value) { int j = find(value); if(j==nElems) // can't find it return false; else // found it { for(int k=j; k
