Declaring and Defining the function

A set of statements, which performs a particular task is called a function. The program gains modularity by using function. The application is quite easy to understand, read, and edit when they are created with functions. The developer/programmer creates a function and uses main() to call the function. Once the function gets executed, the control is transferred to the main program.

THIS IS MEANT TO BE IN JAVA. What we've learned so far is variables, loops, and we just started learning some array today. The assignment is to get an integer from input, and output that integer squared, ending with newline. But i've been given some instructions that are kind of confusing to me. Please explain why and please show what the end result is. Here are some extra things i've been told to do with the small amount of code i've already written... Type 2 in the input box, then run the program so I can note that the answer is 4 Type 3 in the input box instead, run, and note the output is 6. Change the output statement to output a newline: System.out.println(userNumSquared);. Type 2 in the input box Change the program to use * rather than +, and try running with input 2 (output is 4) and 3 (output is now 9, not 6 as before). This is what I have so far... import java.util.Scanner; public class NumSquared {public static void main(String[] args) {Scanner scnr = new…
hello how are you? can you Please code this in Java .. dont use advanced coding and dont edit the whole code and only start editing from where it is menthioned in the code. Please follow the instructions as it is and please see that the input and output are exactly as same as provided in the image. thank you. Write a program that reads a list of integers from input and determines if the list is a palindrome (values are identical from first last to first and last to first). The input begins with an integer indicating the length of the list that follows. Assume that the list will always contain fewer than 20 integers. Output 'yes" if the list is a palindrome and "no' otherwise. The output ends with a newline.
/** 2. Write the method named countChar() * You are given a String str, and a char ch. Return the number of times that ch appears inside str, but ignore case. * * * Oh, and you can't use the classification methods in the Character class. Use plain if statements, remembering that you can check if ch is lowercase by checking if it is between lowercase 'a' and lowercase 'z', inclusive. Likewise, check if between 'A' and 'Z' for capital. To convert lowercase to uppercase, subtract the difference between lowercase 'a' and uppercase 'A' ('a'-'A') from the lowercase character. Add this difference to convert from uppercase to lowercase. * * * * * * Examples: countChar("Abcdefg", 'a') returns 1 countChar("xxXx", 'x') returns 4 countChar("", 'q') returns 0 * * @param str the String to search through @param ch the char to count (not case sensitive) @return the count of ch in str * */ public int countChar(String str, char ch) { // Complete the countChar method here }
