When reading data from a text file, it is common to see numbers such as 12,345, $20, or 195*. Write a method that cleans a string containing digits by removing any characters that are not a digit or a - sign. Then convert to an integer and return the result. Numbers.java 1 public class Numbers 2 { /** Cleans a string containing an integer and converts it. @param number a string containing an integer and possibly extra characters @return the value of the number inside the string * / blic static int clean(String number) { 4 5 7 8 9 10 11 } 12 }

create a class that asks a user for 2 string inputs (USE The Java. Util. SCANNER) -compare the two strings and output if they are equal or not. -check the length of the 2 strings. then compare the two (in terms of length) -thereafter, for the largest string, ask the user to input a character and determine if the string contains that specific character ..... e.g. The word is "star" and the user enters 'a'. The program should output either True or False 2) Create another method within the same class that will check if a sequence of characters (String) entered by the user to determine whether or not the String contains that specific sequence. -You can use the user input from Q1 to determine if the string contains the sequence of characters. You need to create atleast 2 methods (excluding the main method). Atleast one Method needs to take in argument and return some value 3) Create a Person class that…
The extraterrestrials living in the planet Numerion revere a specific type of integers N. In particular, for those creatures, an integer N is holy if there exists an integer i >= 1 such that:N = i*i + iHere are some examples of holy numbers:2 (because 2 = 1*1 + 1) 6 (because 6 = 2*2 + 2) 12 (because 12 = 3*3 + 3) In a file called Numerion.java, write a program that: Asks the user to enter an integer N. It is OK if your program crashes when the user does not enter a valid integer. Prints out whether that number is a holy number in planet Numerion. For example: if the user enters 25, your program output should look EXACTLY like this: Enter an integer N: 25 25 is not a holy number in Numerion. Exiting... As another example: if the user enters 12 (a holy number, since 12 = 3*3 + 3), your program output should look EXACTLY like this:Enter an integer N: 12 12 is a holy number in Numerion. Exiting...
In java, without Arrays and using only String methods ( don't use String builder) // Question 17: In MS-DOS, a file name consists of up // to 8 characters (excluding '.', ':', backslask, '?', // and '*'), followed by an optional dot ('.' character) // and extension. The extension may contain zero to three // characters. For example, 1STFILE.TXT is a valid filename. // Filenames are case-blind. // // Write and test a method that takes // in a String, validates it as a valid MS-DOS file // name, appends the extensions ".TXT" if no extension // is given (that is, no '.' appears in FILENAME), converts // the name to uppercase, and returns the resulting string // to the calling method // If fileName ends with a dot, remove that dot and do not // append the default extension. If the name is invalid, // validFileName should return null. public String validFileName(String n) { }

This is the question I am stuck on - Write an application that accepts any number of String values from a user until they enter zzz or have entered 15 strings, and display them in ascending order. This is the code I have started to try but I am honestly just confusing myself more - import java.util.*; public class StringSort2 { public static void main(String[] args) { // Write your code here Scanner input = new Scanner(System.in); String values; int x; System.out.println("Please enter your values: "); values = input.nextLine(); for(x=15; x < values.length; ++x) System.out.println(values[x] + " "); } }
Given the String String str = “Zhrx.aghkio.Gko123”; (a) Write Java code using the String class methods indexOf and substring to extract the three string surrounded by the periods. In other words String s1 will contain Zhrx, String s2 will contain aghkio and String s3 will contain Gko123. (b) Write a method of the form public static String minstr(String str1, String str2) which returns the string which is “smaller” based on the decimal values of the characters in the string. Thus, Zaa would be “smaller” than bxy because the character Z has a lower decimal values than b. Use the String method compareTo as part of your code. (c) In main, print the value returned by minStr(minStr(s1,s2),s3)
can you please write in java.util.scanner form ,can you please make it so i can copy and past it int[] numbers = {345, 632, 675, 157, 834, 294, 832};1. Write a method to find its highest value. 2. Write a method to find its lowest value. 3. Write a method to find its total value.
Write a java program call CountVowelsDigits which prompts the user for a string, counts the number of vowels(a,e,i,o,u,A,E,I,O,U) and digits(0-9) contain in the string, and prints the counts and percentages rounded to 2 decimal places. Enter a String : testing12345 Number of vowels is: 2 (16.67%) Number of digits is : 5 (41.67%)
Write a method public static intreadInFile(String line, File file) that returns the position numberof a line in the file filename or −1 if there is no such line or file.We assume that this file contains names of people with a name per line.Names (and hence lines) are listed in ascending alphabetical order in the file.We can not find the same line twice.
Write a program that reads a text file named as “input.txt” and performs the following operations:1. Write each word in the text file in reverse order to the file named as“output.txt” . (Example: If the text file contains ”Hello World!”, then itshould write to the output file ”olleH dlroW!”)2. Print the number of words.3. Print the number of words starting with a capital letter.4. Print the number of words that contain no characters other than Englishletters.In this challenge you are supposed to:1. Comment every function with a description explaining what it does andhow it does it.2. Research and learn how to read and write into text files by using properlibrary functions in C.In your program, you can assume that1. Both the input file (input.txt) and the output file (output.txt) will beplaced on the same folder as your program’s executable (.exe).2. In the input file, the length of the words will be at most 100.
IN JAVA Write a program that replaces each line of a file with its reverse. For example, if you run java Reverse HelloPrinter.java Create the output as HelloPrinterReverse.java. If the file HelloPrinter.java contains the text public class HelloPrinter { public static void main(String[] args) { // Display a greeting in the console window System.out.println("Hello, World!"); } } ?? then the contents are changed to retnirPolleH ssalc cilbup { )sgra ][gnirtS(niam diov citats cilbup { wodniw elosnoc eht ni gniteerg a yalpsiD // ;)"!dlroW ,olleH"(nltnirp.tuo.metsyS } } If there is a blank line in the input file, do not print it in the output file. If you run Reverse twice on the same file, you get back the original file. Create the output file as HelloPointerOriginal.java java Reverse HelloPrinterReverse.java If the input file doesn’t exist, throw the message “Input file not found. Please check an rerun the program”. Allow the user to enter the input file one more time. If the user enters an…
In Java please. Only aswer the code where it says "/* Your code goes here */". Write a method lastNameFirst that takes a string containing a name such as "Harry Smith" or "Mary Jane Lee", and that returns the string with the last name first, such as "Smith, Harry" or "Lee, Mary Jane". import java.util.Scanner; public class Names{ /** Changes a name so that the last name comes first. If name has no spaces, it is returned without change. @param name a name such as "Mary Jane Lee" @return the reversed name, such as "Lee, Mary Jane". */ public static String lastNameFirst(String name) { /* Your code goes here */ } public static void main(String[] args) { Scanner in = new Scanner(System.in); String name = in.nextLine(); System.out.println(lastNameFirst(name)); }}
