Use a for loop to generate an array of ten random integers, all in the range from 100 to 200, inclusive. Use the Arrays class to both sort and display the entire array. Next, pass the array as the sole argument to a method that doubles each element of the array and then returns the array. Use a foreach loop to show all elements in the returned array on one line separated by a single space. This latter loop should also determine the sum of all elements in the returned array.

Write a class named Distance that contains the following two methods, then write a test program named TestDistance that uses just one loop to generate the table below. TestDistance should run both statiic methods below in the loop.

Write a program that generates a table showing the sine, cosine, and tangent for angles from 0 to 90 degrees. Each line in the table should increment the angle by 5 degrees. Include column headings.

Hi there i am so sorry to bother with such a length question but i am unable to do it. I am struggling with the following question:

Once the user starts the thread by clicking a button, the program must choose a random image out of an image array, and display the image in the center. When the program starts, the user must be prompted for their name. The time must also be displayed (hh:mm) and must be part of the thread, to keep it updated. The pictures name must be displayed in the appropriate box. When the user stops the thread, the picture name must be cleared and the component in which the image was found must be set to a random color. The thread must also be stopped when the exit button is clicked.

i have an assignment to create a subject marks calculator in java netbeans, I've already done the GUI which includes the labels : mark, total, percentage, textfields for those 3. i have to find the percentage and the coding must be done in a calculate button and the percentage must appear in the percentage label when running the program. This is the code i have :

public static void main(String[] args){
int total, score;
float percentage;
Scanner inputNumScanner = new Scanner(System.in);

System.out.println("Enter the total, or max, score: ");
total = inputNumScanner.nextInt();

System.out.println("Enter the score obtained: ");
score = inputNumScanner.nextInt();

percentage = (score * 100/ total);

System.out.println("The percentage is = " + percentage + " %");
}

but the problem is that it is not appearing in the GUI.

1. encrypt the information word by word.
2.use the last alphabetic character in each word as the key for encrypting that word.
3.consider the value of each alphabetic character as its alphabetic position i.e.
a=A=1
b=B=2
and so on
z=Z=26
1.for every word use the last alphabetic charater in the world as the key.replace all the
alphabetic character in the word with new alphabetic characters formed by subtracting the key value
from each character.
2.key character(last alphabetic character in each word)should not be encrypted.
3.encryption should be performed only on alphabetic characters and not on non-alphabetic character
such as digits or special character.
4.all alphabetic characters should be preserved as uppercase in their respective position but should be replaced with the new character.

In a class room everyone is very friendly and has bonded with others in a short span of time.
