Write a Java application that calculates the sum of a series of integers that are passed to method sum() using a variable-length argument list. Test your method with several calls, each of which with different number of arguments

in Java   Read the input line one at a time. If you read less than 200 lines output nothing. If you read less than 500 lines then output the 200th line in sorted order of the input lines. If you read more than 1000 or more lines, then only consider the last 1000 lines, and output the 200th line in sorted order from the last 1000 lines. Do not store more than 1001 lines.

Write a program called Guests.java that prompts a user to enter how many guests he will host. Next, reads a series of the names into an array of Strings using Scanner, and then prints back "Welcome" to all of those guests.

An incomplete program named w_pl java, which must include three methods, is provided. You must implement two methods within the program as described below. The third method, which is a main method, is already written in the program and you can use it to test your program. The two methods you mast inplement are: • find method • Signature: public statie vold find(int[] a, int x) • Behavior: • Reccives an array of integers a and an integer x • Performs a linear search on a for x. • If x is in a, print the indexes of the aray slots where x is stored (there may be multiple x's in a) on the screen. • Ifx is not in a, print the message "x does not exist" on the screen. Note that you should not use Java's built-in method. Your program must scan and search the array. • isPrifie method • Signature: public statie boolean isPrefix(String s1, String s2) • Behavior: • Receives two strings sl and s2. Assume that length of sl length of s2. Returns true if sl is a prefix of s2 and returns false…

JAVA PROGRAM

Write a complete Java program that does the following: 1. Ask the user to enter the last number and the second last number of his / her student ID. 2. Stores the entered numbers in adequate variables. 3. Finds and prints the following using "printf": The sum of the two numbers. The boolean value of comparing the equality of the two numbers using the equality operator. The value of the first number is raised to the power of the second number using a method from the class Math. Note: The class name of your Java program must be your first name. Your answer should have the code as text as well as the screenshot of the program output (using your own student ID) as a part of your answer. Otherwise, zero marks will be awarded. A typical run of the program Compile Messages JGRASP Messages Run 1/0 Interactions End Clear Help GRASP x Java Question 2 Enter the last amber of your student ID Enter the second last number of your student ID 2 The sum of 5+2=7 (5 is equal to 2) false 3 to the power of…

Define the method printValue() that takes two integer parameters and outputs the product of all integers starting with the first and ending with the second parameter, followed by a newline. The method does not return any value. Ex: If the input is 3 7, then the output is: 2520 Note: Assume the first integer parameter is less than the second. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16     import java.util.Scanner;   public class ValuePrinter {   /* Your code goes here */   publicstaticvoidmain(String[] args) { Scannerscnr=newScanner(System.in); intnumber1; intnumber2;   number1=scnr.nextInt(); number2=scnr.nextInt(); printValue(number1, number2); } }

Write a Java program Factorials that implements the static method factorialOfN() that evaluates the factorials of the integers from 1 to input N. Factorials are used frequently in probability problems. The n!n! - factorial of a positive integer n (written and pronounced “n factorial”) is equal to the product of the positive integers from 1 to nn. Display the results in tabular format.  Each output must have the same structure shown in the example in the first picture. The whole code must have the structure shown in the second picture

Write a complete Java program that allows users to enter two integer numbers as follows: pleaes Enter the first number:  2 please Enter the Second number:  2   Upon providing the two integer numbers, the users should be given a list of operations to select from, as follows: please choose the operation you want to do with these numbers by Enter a,b or c: a- adding  b- multiplying  c- average Based on the users’ selection, a method should be called to perform the selected operation and return the result. After that the main method should print the result. The output of the program should be as follows in the picture:

Write a python code using IntegerRoot class that calculates integer nth root of a number m ifits nth root is an integer. For example: (m,n) where m = 1881676372240757194277820616164488626666147700309108518161,n = 3, then the integer nth root of m (i.e. the integer cubic root of m ) is: rgives an out put r = 12345678900987654321.
