In this challenge, we're going to use loops to help us do some simple math.

  Task Given an integer,  , print its first   multiples. Each multiple   (where  ) should be printed on a new line in the form:  N x i = result . Input Format A single integer,  . Output Format Print   lines of output; each line   (where  ) contains the   of   in the form: N x i = result . Sample Input 2 Sample Output 2 x 1 = 2 2 x 2 = 4 2 x 3 = 6 2 x 4 = 8 2 x 5 = 10 2 x 6 = 12 2 x 7 = 14 2 x 8 = 16 2 x 9 = 18 2 x 10 = 20 Solution: import java.io.*; import java.math.*; import java.security.*; import java.text.*; import java.util.*; import java.util.concurrent.*; import java.util.function.*; import java.util.regex.*; import java.util.stream.*; import static java.util.stream.Collectors.joining; import static java.util.stream.Collectors.toList; public class Solution {     public static void main(String[] args) throws IOException {         BufferedReade...

Java's System.out.printf function can be used to print formatted output. The purpose of this exercise is to test your understanding of formatting output using printf. To get you started, a portion of the solution is provided for you in the editor; you must format and print the input to complete the solution.

  Input Format Every line of input will contain a  String  followed by an  integer . Each  String  will have a maximum of   alphabetic characters, and each  integer  will be in the inclusive range from   to  . Output Format In each line of output there should be two columns: The first column contains the  String  and is left justified using exactly   characters. The second column contains the  integer , expressed in exactly   digits; if the original input has less than three digits, you must pad your output's leading digits with zeroes. Sample Input java 100 cpp 65 python 50 Sample Output ================================ java 100 cpp 065 python 050 ================================ Solution: import java.util.Scanner; public class Solution {     public static void main(String[] args) {             ...

In this challenge, you must read an integer, a double, and a String from stdin, then print the values according to the instructions in the Output Format section below. To make the problem a little easier, a portion of the code is provided for you in the editor.

  Note:   We recommend completing   Java Stdin and Stdout I   before attempting this challenge. Input Format There are three lines of input: The first line contains an  integer . The second line contains a  double . The third line contains a  String . Output Format There are three lines of output: On the first line, print  String:  followed by the unaltered  String  read from stdin. On the second line, print  Double:  followed by the unaltered  double  read from stdin. On the third line, print  Int:  followed by the unaltered  integer  read from stdin. To make the problem easier, a portion of the code is already provided in the editor. Note:  If you use the  nextLine()  method immediately following the  nextInt()  method, recall that  nextInt()  reads integer tokens; because of this, the last newline character for that line of integer input is still queued in...
