How to find the Entry with largest Value in a Java Map

Given a map in Java, the task is to find out the entry in this map with the highest value.


Input: Map = {ABC = 10, DEF = 30, XYZ = 20}
Output: DEF = 30

Input: Map = {1 = 40, 2 = 30, 3 = 60}
Output: 3 = 60


  1. Iterate the map entry by entry
    for (Map.Entry entry : map.entrySet()) 
        // Operations
  2. Store the first entry in a reference variable to compare to initially.
  3. If the current entry’s value is greater than the reference entry’s value, then store the current entry as the reference entry.
  4. Repeat this process for all the entries in the map.
  5. In the end, the reference variable has the required entry with the highest value in the map.
  6. Print this entry

Below is the implementation of the above approach:





// Java program to find entry
// with the highest value in a map
import java.util.*;
public class GFG {
    // Find the entry with highest value
    public static <K, V extends Comparable<V> > Map.Entry<K, V>
    getMaxEntryInMapBasedOnValue(Map<K, V> map)
        // To store the result
        Map.Entry<K, V> entryWithMaxValue = null;
        // Iterate in the map to find the required entry
        for (Map.Entry<K, V> currentEntry : map.entrySet()) {
            if (
                // If this is the first entry, set result as this
                entryWithMaxValue == null
                // If this entry's value is more than the max value
                // Set this entry as the max
                || currentEntry.getValue()
                       > 0) {
                entryWithMaxValue = currentEntry;
        // Return the entry with highest value
        return entryWithMaxValue;
    // Print the map
    public static void print(Map<String, Integer> map)
        System.out.print("Map: ");
        // If map does not contain any value
        if (map.isEmpty()) {
        else {
    // Driver code
    public static void main(String[] args)
        Map<String, Integer> map
            = new HashMap<>();
        map.put("ABC", 10);
        map.put("DEF", 30);
        map.put("XYZ", 20);
            "Entry with highest value: "
            + getMaxEntryInMapBasedOnValue(map));



Map: {ABC=10, DEF=30, XYZ=20}
Entry with highest value: DEF=30
