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

• Last Updated : 17 Mar, 2020

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

Examples:

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

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

## Recommended: Please try your approach on {IDE} first, before moving on to the solution.

Approach

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` ` > Map.Entry``    ``getMaxEntryInMapBasedOnValue(Map map)``    ``{``        ``// To store the result``        ``Map.Entry entryWithMaxValue = ``null``;`` ` `        ``// Iterate in the map to find the required entry``        ``for` `(Map.Entry 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()``                           ``.compareTo(entryWithMaxValue.getValue())``                       ``> ``0``) {`` ` `                ``entryWithMaxValue = currentEntry;``            ``}``        ``}`` ` `        ``// Return the entry with highest value``        ``return` `entryWithMaxValue;``    ``}`` ` `    ``// Print the map``    ``public` `static` `void` `print(Map map)``    ``{`` ` `        ``System.out.print(``"Map: "``);``        ``// If map does not contain any value``        ``if` `(map.isEmpty()) {``            ``System.out.println(``"[]"``);``        ``}`` ` `        ``else` `{``            ``System.out.println(map);``        ``}``    ``}`` ` `    ``// Driver code``    ``public` `static` `void` `main(String[] args)``    ``{`` ` `        ``Map map``            ``= ``new` `HashMap<>();``        ``map.put(``"ABC"``, ``10``);``        ``map.put(``"DEF"``, ``30``);``        ``map.put(``"XYZ"``, ``20``);`` ` `        ``print(map);`` ` `        ``System.out.println(``            ``"Entry with highest value: "``            ``+ getMaxEntryInMapBasedOnValue(map));``    ``}``}`
Output:
```Map: {ABC=10, DEF=30, XYZ=20}
Entry with highest value: DEF=30
```
