Answer 2

You initialize an array in the following format:
```
int numOfArrayElements = 2;
String[] strArrayVariable = new String[numOfArrayElements];
//now you've essentially created 2 string variables --
//one called
//strArrayVariable[0];
//and the other called
//strArrayVariable[1];
//now I''ll assign them both to a string value:
strArrayVariable[0] = "Hello";
String space = " "; //holds a space
strArrayVariable[1] = "World";

//and display
System.out.print(strArrayVariable[0] + space + strArrayVariable[1]);

```

Your question reads in from the keyboard; if you are familiar with the scanner class, then you can use process of elimination -- if not, I can teach you the scanner class if you want.

Answer 3

note the [] after the data type, and the [] again at the end.. I'll show some other examples:

```
int[] intArray = new int[5]; //5 arrays intArray[0] - intArray[4]
double[] dubArray = new double[6323]; //6323 arrays dubArray[0] - [6322]
String[] strArray = new String[1]; //1 string array of strArray[0]

//now I'll extract the number of elements of each array:
int intArrayElements = intArray.length;
int dubArrayElements = dubArray.length;
int strArrayElements = strArray.length;
System.out.println((intArrayElements + dubArrayElements +
strArrayElements)); //prints out 6329

//notice none of the arrays hold values yet.. now I'll
//assign 1 - 6323 to the dubArray element
for(int i = 0; i < 6323; i++)
dubArray[i] = i+1;

//now dubArray holds 1-6323
//now print out the 6323 numbers in ascending order:

for(int i = 0; i < 6323; i++)
System.out.println(dubArray[i]);
```
