How can I sort a Map Key, Value by Values in Java?

To sort a Map Key, Value by values, you can convert it to a List of entries and then use Collections. Sort with a custom comparator that compares the values. Example:

Map<String, Integer> map = new HashMap

map. Put (“a”, 3)

map. Put (“b”, 1)

map. Put (“c”, 2)

List<Map. Entry<String, Integer>> list = new Array List<>(map.entrySet

In Java, you can sort a Map by its values using the following approaches:

• Using Java 8 Stream API
• import java.util.HashMap;
• import java.util.LinkedHashMap;
• import java.util.Map;
• import java.util.stream.Collectors;

public class Main – public static void main (String args {Map<String, Integer> map = new HashMap<>

map.put(“John”, 25)

map.put(“Alice”, 30)

map.put(“Bob”, 20)

• LinkedHashMap::new
• System.out.println(sortedMap)
• Using Comparator and TreeMap
• import java.util.Comparator;
• import java.util.Map;
• import java.util.TreeMap;
