Answer:
Following are the types of installation matched to its respective definitions.
<h3>Upgrade installation:</h3>
What you do when you have a computer with an existing operating system that needs to be upgraded.
This means that while working on a window when you get attracted by the update introduced recently and you upgrade your window accordingly.
For example: Updating a window from 8 to 10 or desired features.
<h3>Multiple boot installation:</h3>
What you do when you have several operating systems on one computer.
In this type of installation, a computer has different windows for different accounts. You can boot to the desired installed window by switching account.
<h3>Clean installation:</h3>
What you do on a brand new computer that has never been set up before and does not have an operating system on it yet.
It can be defined as the installation of window done very first time on to the computer. Sometimes when the window gets deleted due to virus or any other factor, the installation at that time will also be termed as Clean Installation.

Answer:
Implicit type casting means the type casting done by the compiler during compilation of program whereas Explicit type casting means the programmer explicitly type casts the variables. This is the difference implicit and explicit type casting.
Explanation:
Type casting means the conversion of one data type into another data type. There are two types of type casting. They are Implicit type casting and Explicit type casting.
<u>Implicit type casting:</u> The type casting which is done by the compiler during the compilation of a program. This occurs when we assigning smaller data type to larger data type and also both the data type are compatible. Below example clears the above concepts.
Ex: 
In the above example " i " is " int " data type whereas " l " is long data type but as we assigned the value of " i " to " l ". Here " int " and " long " are compatible data types and we assigned smaller data type ( int - i ) to larger data type ( long - l ) implicit type casting occurs.
<u>Explicit type casting:</u> The type casting which is done by the programmer explicitly to convert one data type into other data type. If we want to assign a value of larger data type to smaller data type explicit type casting is required. Below example clears the above concepts.
Ex: 
In the above example " d " is " double " data type whereas " l " is " long " data type. Here we are explicitly type casting to change larger data value ( double - d ) to smaller data value ( long - l ).
Answer:
Boundary folding method is basically used in the java algorithm and in the hash table. In the hash function, the left and the right value are basically folded in the fixed boundary between the given center values by using the boundary folding methods.
There are basically two types of folding method in the hashing that are:
- Folding shift
- Folding boundary
In the folding boundary method the outside value are get reversed and the alternate values are get flipped at the boundary folding method.

Check the explanation
Explanation:
// include the necessary packages
import java.io.*;
import java.util.*;
// Declare a class
public class DataReader
{
// Start the main method.
public static void main(String[] args)
{
// create the object of scanner class.
Scanner scan = new Scanner(System.in);
// Declare variables.
boolean done = false;
boolean done1 = false;
float sum = 0;
double v;
int count = 0;
// start the while loop
while (!done1)
{
// start the do while loop
do
{
// prompt the user to enter the value.
System.out.println("Value:");
// start the try block
try
{
// input number
v = scan.nextDouble();
// calculate the sum
sum = (float) (sum + v);
}
// start the catch block
catch (Exception nfe)
{
// input a character variable(\n)
String ch = scan.nextLine();
// display the statement.
System.out.println(
"Input Error. Try again.");
// count the value.
count++;
break;
}
}
// end do while loop
while (!done);
// Check whether the value of count
// greater than 2 or not.
if (count >= 2)
{
// display the statement on console.
System.out.println("Sum: " + sum);
done1 = true;
}
}
}
}
Sample Output:
Value:
12
Value:
12
Value:
ten
Input Error. Try again.
Value:
5
Value:
nine
Input Error. Try again.
Sum: 29.0
