JAVA - Please complete the following method Integer2Boolean() in bold below:

/*

*/

import binarytree.*;

/** A program that tests the integer2Boolean() method. */ public class Integer2Boolean { /** A method that converts a binary tree of integer values into a bnary tree of booleans, true for even integers and false for odd integers. */ public static BTreeLinked integer2Boolean(BTree btree) {

}

// A simple test case for integer2Boolean(). public static void main(String[] args) { BTree btree1 = new LinkedBTree<>(1, new LinkedBTree<>(12), new LinkedBTree<>(123));

BTree btree2 = integer2Boolean( btree1 );

System.out.println( btree1 ); BTree2dot.btree2dot(btree1, "btree1"); BTree2png.btree2png("btree1");

System.out.println( btree2 ); BTree2dot.btree2dot(btree2, "btree2"); BTree2png.btree2png("btree2"); } }
