How to do this same using JDK 8 features???

[@varanasivamsikrishna7795]

1) convert the array to list
2) Then, list.stream().collect(Collectors.groupingBy(Function.indentity(), Collectors.counting()));

[@ashishsingh8222]

Map numsInMap = Arrays.stream(nums).boxed()
.collect(Collectors.groupingBy(x -> x, Collectors.counting()));
numsInMap.entrySet().forEach(x -> System.out.println(x.getKey() + " -> " + x.getValue()));
for java 8
