Allow a user to enter any number of double values up to 15. The user should enter 99999 to quit entering numbers. Display an error message if the user quits without entering any numbers; otherwise, display each entered value and its distance from the average. Write Java code please import java.util.*; public class DistanceFromAverage { public static void main (String[] args) { // Write your code here } }
When the given integer variable numberOfTools is: less than 14, output "Small tool box". between 14 inclusive and 39 inclusive, output "Mid-sized tool box". greater than 39, output "Need wall storage". End with a newline. Ex: If the input is 13, then the output is: (in java) Given Code: import java.util.Scanner; public class ToolDetails {public static void main(String[] args) {Scanner scnr = new Scanner(System.in);int numberOfTools; numberOfTools = scnr.nextInt();
Write a java code for this problem General Statement: Read a string and determine whether each left parenthesis ‘(‘ has a matching right parenthesis ‘)’. Input: The first line of the data set for this problem is an integer that represents the number of strings that follow. Each string is on a separate line. Output: Output either MATCH or NO MATCH. All letters are upper case. The output is to be formatted exactly like that for the sample output given below. Assumptions: All letters are upper case. ( and ) are the only enclosure symbols in the string. Discussion: The left parenthesis must come before the right parenthesis in order to count as a matched set of parentheses. Sample Input: 3(3 + (7 * 2) – 6) HELLO AND (WELCOME (TO THE) TCEA (CONTEST) TODAY) IS ((SATURDAY()) Sample Output: MATCHNO MATCH NO MATCH

Problem specification: There is a grid of NXN squares. We can easily determines how many different rectangles (squares are excluded) there are in the grid. For example, in a 3X3 grid, you can find 22 different rectangles, marked as the green rectangles. You can see that we did not count the red ones as they are squares. In this assignment, you will write a Java program that takes the value of N as input and determines the total area of all the rectangles in the grid. Assume that the smallest squares in the grid have length 1. So a 3X2 rectangle will have an area of 6. For example, the total area of all the rectangles in the 3X3 grid is 66.…

How do I code: If the difference is positive, return “a is bigger by” + diff. If the difference is negative, return “b is bigger by” + diff. If there is NO difference between the two numbers, return “EQUAL” in Java.
