This is false. Data warehousing is storing the data. Data mining is retrieving and analyzing data from the data warehouse.
It is grouped according to raster and vector format. Raster format are images used in a computer or printed. Vector format stores data and is compressed.
Examples of common raster formats usually used in a computer are; jpeg, png, bitmap, and gif. Vector formats are; CGM, SVG and 3D vector.
Answer:
The program displays 5 4 3 2 1 and then raises an Array Index Out Of Bounds Exception.
Explanation:
A sample of code output is attached.
The code snippet contain xMethod that takes an array and array length as argument.
In the given snippet, the array {1, 2, 3, 4, 5} and length (5) is passed as argument to the method.
First the method display the element of the array in reverse order
System.out.print(" " + x[length - 1]);
and then the method call itself again. This displays
5 from x[4]
4 from x[3]
3 from x[2]
2 from x[1]
1 from x[0]
but after displaying 1, when it tries to call the method again, an array index out of bound exception is thrown because it will try accessing an element from the array when it is already exhausted.
import java.util.Scanner;
public class U2_L3_Activity_Four {
public static void main(String[] args) {
Scanner scan = new Scanner(System.in);
System.out.println("Enter a sentence.");
String sent = scan.nextLine();
int count = 0;
for (int i = 0; i < sent.length(); i++){
char c = sent.charAt(i);
if (c != ' '){
count++;
}
else{
break;
}
}
System.out.println("The first word is " + count +" letters long");
}
}
We check to see when the first space occurs in our string and we add one to our count variable for every letter before that. I hope this helps!
