## Arrays (Cont.)
|
|
|
|
### Another way of Array Initialization
|
|
|
|
```java
|
|
String[] names = {"Jennifer", "Noodle", "Fluffy", "Rosie", "Cinnamon", "Brianne", "Oliver"}
|
|
```
|
|
|
|
Everything between the `{}` is the initial values in the names array in the order that it is written.
|
|
|
|
Recall that arrays are of a fixed size. The `names` array above has 7 elements.
|
|
|
|
### What can I do if I want to add something to the names array?
|
|
|
|
Do the following steps:
|
|
|
|
1. Create an empty array with the same size as the array
|
|
2. Take all the contents in the array and store it in a temporary array
|
|
3. Set names equal to another array of a bigger size
|
|
4. Take all the contents in temp and store it back to the array of choice
|
|
5. Add an element to the array by index
|
|
|
|
```java
|
|
// (1)
|
|
String[] temp = new String[7];
|
|
// (2)
|
|
temp.clone(names);
|
|
// (3)
|
|
names = new String[20]; // Now it can hold up to 20 names
|
|
// (4)
|
|
names.clone(temp);
|
|
// (5)
|
|
names[7] = "New name!";
|
|
```
