Create a function that tallies the number of times a phrase appears in a string. The function's output should be a number. Don't presume that a single space divides words, and that a string can contain punctuation. Create the method so that it can accept a String input or a StringBuilder object.
Step by step
Solved in 4 steps with 2 images
- Create a code that tracks how many times a phrase appears in a string. A number should be the function's output value. Never presume that a series of words can contain punctuation and only one space between words. Create the method so that it accepts a String argument or a StringBuilder object as a parameter.Write a method that accepts a String object as an argument and displays its contents backward.For instance, if the string argument is “gravity” the method should display -“ytivarg”.Demonstrate the method in a program that asks the user to input a string and then passes itto the method.JAVAA7-Write a class with a constructor that accepts a String object as its argument. The class should have a method that returns the number of vowels in the string, and another method that returns the number of consonants in the string. Demonstrate the class in a program by invoking the methods that return the number of vowels and consonants. Print the counts returned.
- Create class that performs different functions on Strings that are sent to it. All the methods you create will be static. Only two methods (mentioned below) and the main method need to be public. Any other methods that you write to help these methods should be private because they are only used internally within the class. Requirements: 1. Prompt users to enter 3 string inputs. Consider strings with alphabetic characters (a - z, A - Z) and/or numbers (0 - 9) as valid. Strings contain only non-word characters are invalid. Print the following usage when an input string is invalid or is empty. Usage: Enter a string that contains alphabetic characters and numbers 2. Create a method "isPalindrome" that takes a String as a parameter and returns true if the given String parameter is a palindrome and false if it is not. In your main method, this method should be call with the first user input and print either "The given string is a palindrome." or "The given string is not a palindrome." as…DescriptionA researcher is analyzing DNA. A DNA can be represented as a string composed of the characters A, G, C, or T.One day, researchers found a strange DNA, which is Smooth Repeated DNA. The DNA is represented by a string that has infinite length. The string has a repeating pattern, i.e. the DNA string 0 is repeated an infinite number of times. For example, if0 = "????", then = "???????????? . . . ".According to researchers, a DNA is said to be special if it contains substrings . Determine whetheris a substring of . Squad FormatA line containing the two strings 0 and . Output FormatA line that determines whether it is a substring of . Issue “YES” ifis a substring of . Output “NO” otherwise.

For instance, if the argument is “hello.my name is Joe. what is your name?” the method should return the string “Hello. My nameis Joe. What is your name?” Demonstrate the method in a program that asks the user toinput a string and then passes it to the method. The modified string should be displayed onthe screen.*/ import javax.swing.JOptionPane; public class SentenceCapitalizer{public static void main(String[] args){String input;input = JOptionPane.showInputDialog("Enter a string.");JOptionPane.showMessageDialog(null, sentenceCap(input));System.exit(0);} public static String sentenceCap(String…
- In some circumstances, a class is reliant on itself. That is, one class's object interacts with another class's object. To accomplish this, a method of the class may accept an object of the same class as a parameter.The String class's concat function is an example of this situation. The method is called by one String object and receives another String object as an argument. Here's an illustration:str3 is equal to str1.concat(str2);The method's String object (str1) appends its characters to those of the String supplied as a parameter (str2). As a consequence, a new String object is returned and saved as str3. Create Java code to implement the conditions given.In some cases, a class depends on itself. That is, an object of one class interactswith another object of the same class. To accomplish this, a method of the classmay accept as a parameter an object of the same class.The concat method of the String class is an example of this situation. Themethod is executed through one String object and is passed another String object as a parameter. Here is an example:str3 = str1.concat(str2);The String object executing the method (str1) appends its characters to thoseof the String passed as a parameter (str2). A new String object is returned asa result and stored as str3. Write java code to implement given conditionsWrite a program in the StringManipulator class that creates a String variable that references a String object holding the name of your favorite city. The program should display the following: • The number of characters in the city name• The name of the city in all uppercase letters • The name of the city in all lowercase letters • The first character in the name of the city
- 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 accessor method; It returns the changed version of the String. If you want to do something with the returned String - like use replace() on…Create a program that will count the number of numeric characters in an input string. The program should be able to ask the user for the input string and should be able to display the number of numeric characters on the screen. For this exercise, you should create your class to handle the different operations. Remember that any input/output operations should be done in the main method while all calculations should be done inside the class. Remember that you need to apply encapsulation in your class. Sample Output: Enter a string: Hello 123 Number of numeric characters: 3Java Write an executable program that has just a main method. In main: create an instance of StringBuilder that initially holds an empty string. append your first name to the string. append your surname to the string. display your name. insert your middle initial where it should be and spaces as needed. If you don't have a middle name, fake it. display your name with middle initial. delete your initial and the space(s). display your name in reverse order.
