Step by step
Solved in 2 steps
- Alternate Character DisplayWrite a method that accepts a String object as an argument and then returns the alternate characters as substring starting from index 0. For instance, if the string argument passed is “GREAT”, the method should return “GET”. Demonstrate the method in a program that asks the user to input a string and then passes it to the method.True or False: The String class’s replace method can replace individual characters, but cannot replace substrings.All the Same Letter Write a method to determine if all the letters in a String are the same letter. public boolean sameLetter(String str) { //declare first character variable //create statements to compare each character and include return statement //create other return statement }
- C# Write a method that accepts a string as an argument and displaysits contents backward. For instance, if the string argument is"gravity" , the method should display "ytivarg"C sharp Write a method that accepts a string as an argument and checks it for proper capitalization and punctuation. The method should determine if the string begins with an uppercase letter and ends with a punctuation mark. The method should return true if the string meets the criteria; otherwise, it should return false.Scanner method --------------- reads characters until it encounters a newline character, then returns those characters as a String.
- Sentence Capitalizer Create an application with a method that accepts a string as an argument and returns a copy of the string with the first character of each sentence capitalized. For instance, if the argument is "hello. my name is Joe. what is your name?" the method should return the string "Hello. My name is Joe. What is your name?" The application should let the user enter a string and then pass it to the method. The modified string should be displayed.A string object's functions may be used to find out the location of a substring when it is a substring of another string object.True or FalseWhen you call a string object’s Split method, the method divides the string into two substrings and returns them as an array of strings.
- Word Separator Create an application that accepts as input a sentence in which all the words are run together but the first character of each word is uppercase. Convert the sentence to a string in which the words are separated by spaces and only the first word starts with an uppercase letter. For example, the string "StopAndSmellTheRoses." would be converted to "Stop and smell the roses."Password modifier Many user-created passwords are simple and easy to guess. Write a program that takes a simple password and makes it stronger by replacing characters using the key below, and by appending "q*s" to the end of the input string. You may assume that the string does not contain spaces and will always contain less than 50 characters. i becomes ! a becomes @ m becomes M B becomes 8 o becomes . Ex: If the input is: mypassword the output is: Myp@ssw.rdq*s LAB ACTIVITY 4.20.1: LAB: Password modifier 0 / 10 please you c programmingThe ________ method parses a string s to a double value. double.parseDouble(s); Double.parsedouble(s); Double.parseDouble(s); double.parse(s);
