Answer:
import java.util.Arrays;
public class swap{
public static void main(String []args){
int [] arr = {2,4};
swapValues(arr);
}
public static void swapValues(int[] values){
int temp;
System.out.println(Arrays.toString(values));
temp=values[0];
values[0]=values[1];
values[1] =temp;
System.out.println(Arrays.toString(values));
}
}
Explanation:
In the program above, we created the method swapValues that receives an array of integers as parameters. in the method definition, we created a temp variable that is used to swapp the element at index 0 and index 1. Java's Arrays.to string method is used to print the array before and after the swap.
Answer:
Windows 8.1 Core
Explanation:
In this particular example, we're going to use Windows 8.1 Core, is the most basic of the window's family, in this case, only we need an OS to connect the hardware with the cloud computing for security and is not necessary another license, in addition, Windows 8.1 core is easiest to use, is so friendly with the user.
Answer / Explanation:
Coordination numbers, grain growth in ice, and till deformation.
The Web of Science lists 5 papers that Dr. Alley helped write and that have 1986 publication dates. Dr. Alley was studying why some parts of the Antarctic ice sheet move rapidly, and helped learn that deformation of a special type of mud beneath, called till, was involved. He also was studying the physical properties of ice cores, including why and how some crystals or grains in the ice get bigger over time. Some of the physical properties of the ice cores are related to how many different grains are touching each other, which is the coordination number.
Later, Dr. Alley used his knowledge of physical properties in ice to learn how old ice cores are, and to help learn about climate history from them. The other possibilities listed are all things that he studied, some rather closely related, but that were not published in 1986.
Answer:
Marcia Wilson owns and operates Marcia’s Dry Cleaning, which is an upscale dry cleaner in a well-to-do suburban neighborhood. Marcia makes her business stand out from the competition by providing superior customer service. She wants to keep track of each of her customers and their orders. Ultimately, she wants to notify them that their clothes are ready via e-mail. Suppose that you have designed a database for Marcia’s Dry Cleaning that has the following tables:
Assume that all relationships have been defined, as implied by the foreign keys in this table list, and that the appropriate referential integrity constraints are in place.
Create a dependency graph that shows dependencies among these tables. Explain how you need to extend this graph for views and other database constructs such as triggers and stored procedures.
Assume you want to change the name of the INVOICE table to CUST_INVOICE. Use the following steps to change the table name:
(1) Create a new table with the new name.
(2) Alter any constraints, triggers, or views that may be affected.
(3) Copy all data from the old table to the new table.
(4) Create any needed foreign key constraints
(5) Drop the old table.

Complete Question:
Write code that prints: Ready! userNum ... 2 1 Blastoff! Your code should contain a for loop. Print a newline after each number and after each line of text Ex: userNum = 3 outputs: Ready! 3 2 1 Blastoff!
Answer:
public class TestClock {
public static void main(String[] args) {
int userNum= 3;
System.out.print("Ready! "+userNum+" ");
for (int i=userNum;i>1; i--){
userNum--;
System.out.print(userNum+" ");
}
System.out.println("Blasoff!");
}
}
Explanation:
- Create and initialize userNum
- Use System.out.print to print the sequence ("Ready! "+userNum+" ") on same line
- use for statement with this condition for (int i=userNum;i>1; i--) decremeent userNum by 1 after each loop iteration and print userNum on same line
- outside the for loop print "Blasoff!"
