Code a method that will count the number of digits in a string. The first parameter is of type string, and the second parameter is an output parameter that contains the number of digits. Name the first parameter as input and the second as countDigits.
Step by step
Solved in 3 steps with 3 images
- In java: Complete the checkCharacter() method which has 2 parameters: A String, and a specified index (int). The method checks the character at the specified index of the String parameter, and returns a String based on the type of character at that location indicating if the character is a letter, digit, whitespace, or unknown character. Ex: The method calls below with the given arguments will return the following Strings: checkCharacter("happy birthday", 2) returns "Character 'p' is a letter"checkCharacter("happy birthday", 5) returns "Character ' ' is a white space"checkCharacter("happy birthday 2 you", 15) returns "Character '2' is a digit"checkCharacter("happy birthday!", 14) returns "Character '!' is unknown"The countSubstring function will take two strings as parameters and will return an integer that is the count of how many times the substring (the second parameter) appears in the first string without overlapping with itself. This method will be case insensitive. For example: countSubstring(“catwoman loves cats”, “cat”) would return 2 countSubstring(“aaa nice”, “aa”) would return 1 because “aa” only appears once without overlapping itself. public static int countSubstring(String s, String x) { if (s.length() == 0 || x.length() == 0) return 1; if (s.length() == 1 || x.length() == 1){ if (s.substring(0,1).equals(x.substring(0,1))){ s.replaceFirst((x), " "); return 1 + countSubstring(s.substring(1), x); } else { return 0 + countSubstring(s.substring(1), x); } } return countSubstring(s.substring(0,1), x) + countSubstring(s.substring(1), x); } public class Main { public static void main(String[] args) { System.out.println(Recursion.countSubstring("catwoman loves cats","cat"));…Consider the processWords method. Assume that each of its two parameters is a String of length two or more. public void processWords(String word1, String word2) {String str1 = word1.substring(0, 2);String str2 = word2.substring(word2.length() - 1); String result = str2 + str1; System.out.println(result.indexOf(str2)); } Which of the following best describes the value printed when processWords is called? (A) The value 0 is always printed.(B) The value 1 is always printed.(C) The value result.length() - 1 is printed.(D) A substring containing the last character of word2 is printed.(E) A substring containing the last two characters of word2 is printed.
- The String class has several overloaded versions of a method that accepts a value of any primitive data type as its argument and returns a string representation of the value. The name of the method is ___________.a. stringValueb. valueOfc. getStringd. valToStringT/F 3) The parameter (String[ ] variable) is used in a Java key method such that a user may run the software and supply "command-line" parameters. The operator, on the other hand, does not need to have any parameters since the parameter is a String sequence.Language :Python write a program that asks the user to enter a series of single digit numbers with nothing seperating them. The program should display the sum of all the single digit numbers in the string. For example, if the user enters 2514 the method should return 12, which is hw sum of 2,5,1 and 4. write a program that reads a string from the user containing a date in the form mm/dd/yy. it should print the date in the format March 12, 2018.
- In java language Before we write a class which is used to describe objects, let’s practice manipulating an object by calling its methods. Complete the class LeetMaker class using String methods. Remember that all the String methods are accessors. They do not change the original String. If you want to apply multiple methods to a String, you will need to save the return value in a variable. Complete the class by doing the following: Print the word in lowercase Replace "e" with "3" (Use the unmodified variable word) Print the changed word In the changed word, replace: "t" with "7" Print the changed word In this newest changed word, replace: "L" with "1" (uppercase L with the number 1). Then, print the final changed word (with all the replacements) Print the length of the word The code to print the original word is already included for you. Do not change that statement. You will need to use the replace() method multiple times. Then print the final String. Remember that replace is an…In Java, an identifier, which can be class name or method name, is a series (string) of the following groups/types of characters: {fill/continue from 2) (1) Lower-case alphabet characters: a – z, (2) ……………..… (3) …………….…… (4) ……………... (5) ………….Computer Programming Java Write a method named FirstHalf that receives a String parameter named word and then returns the first half of the string. You are guaranteed as a precondition that word has an even length greater than 1.
- Signature will be public static void changeLetter(StringBuilder sb, String Letters) Make it so any letters from the second parameter found in the String Builder are converted to uppercase. Write in Java and use testcase examples as a reference.In this lab, you complete a partially written Python program that includes built-in methods that convert Strings to all uppercase or all lowercase. The program prompts the user to enter any string. To end the program, the user can enter "done". For each string entered, call the built in methods lower() and upper(). The program should call these methods using a string object, followed by a dot (.), followed by the name of the method. Both of these methods return a string with the string changed to uppercase or lowercase. Here is an example: sample = "This is a String."result = sample.lower(); result = sample.upper(); The source code file provided for this lab includes the necessary input and output statements. Comments are included in the file to help you write the remainder of the program. Instructions Make sure the file ChangeCase.py is selected and open. Write the Python statements as indicated by the comments. Execute the program by clicking on the Run button at the bottom of the…In this lab, you complete a partially written Python program that includes built-in methods that convert Strings to all uppercase or all lowercase.
