Answer
There are a lot of advantages of web based applications.
Explanation:
Below are the advantages:
- Web based applications can be accessed from device that is connected to the device.
- No physical software required to download, install, update or manage which saves a lot of administration work for large companies.
- Web based software is compatible with any device or platform. The software is delivered through a browser of the users' choice.
- Mobile device applications allow for access to the software when out of the office.

Answer:
Int
byte
Explanation:
In java there are eight primitive data types has a class dedicated, and then we can find eight wrapper classes, I'm going to let you the next table with the 8 example:
Assume the next table byte and Int are primitive data, the different with byte is only the capital letter Byte.
Primitive Wrapper Class
boolean Boolean
byte Byte
char Character
int Integer
float Float
double Double
long Long
short Short
Answer:
public class Main
{
public static void main(String[] args) {
System.out.println(starString(4));
}
public static String starString(int n){
double p = Math.pow(2,n);
String s = "";
for(int i=0; i<p; i++)
s += "*";
return s;
}
}
Explanation:
Create a method named starString that takes an integer parameter, n
Get the 2 to the nth power using pow method and set it to the p
Create an empty string that will hold the asterisks
Create a for loop that will iterate p times. Inside the loop, concatenate an asterisk to the s
Return the s
Inside the main method, call the method with an integer parameter
