java hashmap find largest value code example
Example 1: find the greatest number in hashmap
public class NewClass4 {
public static void main(String[] args)
{
HashMap<Integer,Integer>map=new HashMap<Integer, Integer>();
map.put(1, 50);
map.put(2, 60);
map.put(3, 30);
map.put(4, 60);
map.put(5, 60);
int maxValueInMap=(Collections.max(map.values()));
for (Entry<Integer, Integer> entry : map.entrySet()) {
if (entry.getValue()==maxValueInMap) {
System.out.println(entry.getKey());
}
}
}
}
Example 2: find highest value in keyset java
countMap.entrySet().stream().max((entry1, entry2) -> entry1.getValue() > entry2.getValue() ? 1 : -1).get().getKey();
