If the current entry’s key is greater than the reference entry’s value, then store the current entry as the reference entry. Repeat this process for all the entries in the map. In the end, the reference variable has the required entry with the highest key in the map. Print this entry Below is the implementation of the above approach: filter_none edit play_arrow brightness_4 // Java program to find entry // with highest key in a map import java.util.*; public class GFG { // Find the entry with highest key public static &
