write (define) a public static method named countup, that takes one int argument and returns no value. you can safely assume tha

t the argument will always be a positive integer. when this method is called, it should print a count from 1 up to (and including) the argument value.

Using the knowledge of computational language in python it is possible to write a code that write (define) a public static method named countup, that takes one int argument and returns no value.

<h3>Writting the code:</h3>

<em>public class </em><em>Main</em>

<em>{</em>

<em>public static void main(</em><em>String</em><em>[] args) {</em>

<em>// testing the method </em><em>countDown </em><em>with values 5, 6, 1</em>

<em>countDown(5);</em>

<em>System.out.println();</em>

<em>countDown(6);</em>

<em>System.out.println();</em>

<em>countDown(2);</em>

<em>System.out.println();</em>

<em>}</em>

<em />

<em>public static void </em><em>countDown</em><em>(int num)</em>

<em>{</em>

<em>for (int i=1 ; i<=num ; i++) // for </em><em>loop </em><em>iterates from 1 to num</em>

<em>{</em>

<em>System.out.print(i+","); // prints num followed by comma ,</em>

<em>}</em>

<em>}</em>

<em>}</em>

Complete the implementation of the following methods:__init__hasNext()next()getFirstToken()getNextToken()nextChar()skipWhiteSpac
andrey2020 [161]

From method names, I am compelled to believe you are creating some sort of a Lexer object. Generally you implement Lexer with stratified design. First consumption of characters, then tokens (made out of characters), then optionally constructs made out of tokens.

Hope this helps.

           // filling triangle as a polygon

           // passing x, x-length/2, x+length/2 as x coordinates

           // and y, y+h, y+h as y coordinates

Write a program that takes in a line of text as input, and outputs that line of text in reverse. The program repeats, ending whe
Nana76 [90]

<u>Answer:</u>

<em>using System; </em>

<em>public class Program </em>

<em>{ </em>

<em> public static void Main() </em>

<em> { </em>

<em> String input ; </em>

<em> while(true) </em>

<em> { </em>

<em>  input = Console.ReadLine(); </em>

<em>  if(input.Equals(""quit"")) </em>

<em>  break; </em>

<em>  Reverse_String(input); </em>

<em> } </em>

<em> return; </em>

<em> } </em>

<em>static void Reverse_String(string input_text) </em>

<em>{ </em>

<em>    char[] text = input_text.ToCharArray(); </em>

<em>    Array.Reverse(text); </em>

<em>    Console.WriteLine(text); </em>

<em>} </em>

<u>Explanation:</u>

<em>In the above program a separate function is written to reverse the string.</em>

This method takes the string as an argument and place it in a array and then use the built-in function reverse and print the reversed string in the console.

<em>In the main(), the input is obtained from the console and it is passed to the reversestring(). </em>
