- Array of an object is full with specific default  value of that object .
- Resizing an array can be done by copying array to annother one bigger.
using 
```java
System.arraycopy()
Arrays.copyof(<source_array>, <destination_array_size>)
```
- We cann compare arrat content **Arrays.equals(array_1,array_2)**

- We can label loops in Java like that
```java
outerLoopLabel:
for(...){
	for(...){
	
	}
}
// we can do: 
// continue OuterLoopLabel:
// break outerLoopLabel:
```
