Learn Java for free with this interactive course, and get a handle on one of the most popular programming languages in the world.

You'll start with a simple hello world program and proceed to cover common concepts such as Conditional Statements, Loop Statements, Math, and Logic in Java, before moving on to more advanced concepts like Inheritance, Generics, and ArrayLists, along with much more.

By the time you're done, you'll be an intermediate level Java developer, ready to take on your own projects.

## Problem statement

Given a `Character` ArrayList, you have to implement a Java method to remove all the _duplicate elements_ from it.

### Function prototype
```java
void removeDuplicates(ArrayList<Character> arrList)
```
### Output
An ArrayList with all the unique elements.
### Sample input
```java
arrList = [a,b,b,c,c,c,d]
```

### Sample output
```java
arrList = [a,b,c,d]
```
