Can someone please help me with implementing this class of a B+ tree? Help with the algorithm for this class to get me on the right track would be helpful too.

Any help that can be provided is much appreciated, thanks! -------------------------------------------------------------------------------------------------------- import java.io.RandomAccessFile;

import java.util.LinkedList;

public class BTree {

RandomAccessFile f;

int order;

int blockSize;

long root;

long free;

//add instance variables as needed.

private class BTreeNode {

private int count;

private int keys[];

private long children[];

private long address; //the address of the node in the file

//constructors and other method

public BTreeNode() {

}

public BTreeNode(long addr) {

}

}

public BTree(String filename, int bsize) {

//bsize is the block size. This value is used to calculate the order

//of the B+Tree

//all B+Tree nodes will use bsize bytes

//makes a new B+tree

}

public BTree(String filename) {

//open an existing B+Tree

}

public boolean insert(int key, long addr) {

/*

If key is not a duplicate add, key to the B+tree

addr (in DBTable) is the address of the row that contains the key

return true if the key is added

return false if the key is a duplicate

*/

return false;

}

public long remove(int key) {

/*

If the key is in the Btree, remove the key and return the address of the

row return 0 if the key is not found in the B+tree

*/

return 0;

}

public long search(int k) {

/*

This is an equality search

If the key is found return the address of the row with the key

otherwise return 0

*/

return 0;

}

public LinkedList rangeSearch(int low, int high){

//PRE: low <= high

/*

return a list of row addresses for all keys in the range low to high inclusive

return an empty list when no keys are in the range

*/

LinkedList list = new LinkedList<>();

return list;

}

public void print() {

//print the B+Tree to standard output

//print one node per line

//This method can be helpful for debugging

}

public void close() {

//close the B+tree. The tree should not be accessed after close is called

}
