## Using `sort()` Method

### In Ascending Order

```java
Map<Integer, Integer> map = new HashMap<>();
// omitted map population for brevity

List<Entry<Integer, Integer>> list = new ArrayList<>(
	map.entrySet()
);

list.sort(
	Entry.comparingByValue()
);
```

### In Descending Order

```java
Map<Integer, Integer> map = new HashMap<>();
// omitted map population for brevity

list.sort(
	Entry.comparingByValue(
		Comparator.reverseOrder()
	)
);
```

## Using `sorted()` Method

### In Ascending Order

```java
Map<Integer, Integer> map = new HashMap<>();
// omitted map population for brevity

Stream<Map.Entry<Integer, Integer>> sorted = map.entrySet().stream().sorted(
	Map.Entry.comparingByValue()
);
```

### In Descending Order

```java
Map<Integer, Integer> map = new HashMap<>();
// omitted map population for brevity

Stream<Map.Entry<Integer, Integer>> sorted = map.entrySet().stream().sorted(
	Map.Entry.comparingByValue(
		Comparator.reverseOrder()
	)
);
```
