Variables and Constant

Constants and variables are widely used in mathematical equations and expressions. They are also commonly found in the domain of programming, where each language has its own way to differentiate between a constant and a variable. Since they have all sorts of applications, knowing their differences is a good place to start.

In Java Suppose you are given a text file that contains the names of people. Every name inthe file consists of a first name and a last name. Unfortunately, the programmer thatcreated the file of names had a strange sense of humor and did not guarantee thateach name was on a single line of the file. Write a program that reads this file ofnames and writes them to the console, one name per line.For example, if the input file (Names.txt) contains:Bob Jones FredCharles EdMarstonJeffWilliamsThe output should be:Bob JonesFred CharlesEd MarstonJeff Williams Sample Output:Enter the name of the input file:Names.txtBob JonesFred CharlesEd MarstonJeff WilliamsFile processing completed.
Need help writing this java code, it has three objectives: to process strings to compare, search, sort, and verify location of specific pattern to output result via interface Description Write a Java program to read a text file (command line input for file name), process the text file and perform the following. Print the total number of words in the file. (When using java_test.txt, I calculate the number of words, including number, as 254.) Print the total number of different words (case sensitive, meaning “We” and “we” are two different words) in the file. (When using java_test.txt, I calculate the number of different words, including number, as 168.) Print all words in ascending order (based on the ASCII code) without duplication. Write a pattern match method to find the location(s) of a specific word. This method should return all line number(s) and location(s) of the word(s) found in the file. Print all line(s) with line number(s) where the word is found by invoking the method…
Java Your program must read a file called personin.txt. Each line of the file will be a person's name, the time they arrived at the professor's office, and the amount of time they want to meet with the professor. These entries will be sorted by the time the person arrived. Your program must then print out a schedule for the day, printing each person's arrival, and printing when each person goes in to meet with the professor. You need to print the events in order of the time they happen. In other words, your output will be sorted by the arrival times and the times the person goes into the professor's office. In your output you need to print out a schedule. In the schedule, new students go to the end of the line. Whenever the professor is free, the professor will either meet with the first person in line, or meet with the first person in line if nobody is waiting. Assume no two people arrive at the same time. You should solve this problem using a stack and a queue. You can only…
Write a program using while loop and for loops to print first 50 prime numbers in 5 lines, each line containing 10 numbers. 1. Create a program called CountCharacters.java. 2.

Import the Scanner class and ask user to enter a line. Implement the while loop so that the user can input any number of lines and one line at a time. To stop entering lines, the user can write "quit. (Hint: Use the string method <str>.equals() in the while condition to stop the while loop OR a break keyword). 4. Implement the for loop inside the while loop to iterate through the line one character at a time to count and output the number of blank spaces, alphabetic characters, digit characters, and other characters in all the lines. You need to use different methods of character class like charAt(), isDigit(),…

In Java: Forms often allow a user to enter an integer. Write a program that takes in a string representing an integer as input, and outputs yes if every character is a digit 0-9. Ex: If the input is: 1995 the output is: yes Ex: If the input is: 42,000 or 1995! the output is: no Hint: Use a loop and the Character.isDigit() function.
