**Advantages of Arrays**
- **Code Optimization**: It makes the code optimized, we can retrieve or sort the data efficiently.
+ **Random access**: We can get any data located at an index position.
**Disadvantages of Arrays**
- **Size Limit**: We can store only the fixed size of elements in the array. It doesn't grow its size at runtime. To solve this problem, collection framework is used in Java which grows automatically.
