this is a java program code please do the code what in the question says and please follow what in the question says and dont copy or plagarise from other sources 2.Remove Line Numbers in a FileSome lines in the file have a line number, as shown in the following figure. A line number is the firstword in the line. A line number is delimited by one or more whitespace characters. A line numbermay also be preceded with one or more whitespace characters. Write a program that prompts theuser to enter a file name, reads the lines from the file, and replaces the line numbers in the file withappropriate numbers of spaces. For example, you need to replace the line number 2 with one spaceand line number 34 with two spaces, and you should keep the two spaces preceding line number 34.Name your class file as RemoveLineNumber. java. You do not need to submit the .txt file thatyou use to test your program.public class Test {2 This line has a line number, etc.int x = 3594;34 good badpublic class Test {This line has a line number, etc.int x = 3594;good badHints: Hints:a. You can create a .txt file with the above example to test your program. When running your testprogram, you should give the file path starting from the working directory. The default workingdirectory in NetBeans is your project folder. Thus, you should give the file path starting fromyour project folder. Alternatively, you may put your .txt file in the project folder. Then youcan simply use the file name when running your program.andb. To remove the line numbers, you may need to use String methods trim(), matches (),split (). Check the URL https://docs.oracle.com/en/java/javase/20/docs/api/java.base/java/lang/String.html for more information about these methods.Please note that split () has an overloaded version with a second parameter, which might beuseful in this question. And please also note that matches () and split () accept regularexpressions as their parameters.

PYTHON!!!! Write a program that allows the user to navigate the lines of text in a file. The program should prompt the user for a filename and input the lines of text into a list. The program then enters a loop in which it prints the number of lines in the file and prompts the user for a line number. Actual line numbers range from 1 to the number of lines in the file. If the input is 0, the program quits. Otherwise, the program prints the line associated with that number. An example file and the program input and output is shown below: example.txt Line 1. Line 2. Line 3. Enter the input file name: example.txt The file has 3 lines. Enter a line number [0 to quit]: 2 2 : Line 2. The file has 3 lines. Enter a line number [0 to quit]: 4 ERROR: line number must be less than 3. The file has 3 lines.

WriteaC++programthatpromptstheusertoenterafilenamethatcontains the total mark of students. Each line in the input file contains a student name followed by the student’s total mark. The program should ask the user for the passing threshold (i.e. student whose total mark is greater than or equal the threshold will pass the course) and copy the students who pass the course to a new file (the name of the output file is specified by the user). Moreover, the output file should be format so that all the marks are displayed with two digits after the decimal point. The width for the names and marks fields should be eight and seven, respectively. A sample input and output files are shown below (the passing mark in this sample is assumed to be 60).
