I have a question regarding java programming.
If I have this in a text file, " hey you <hello world> "
How can I get it so that it only extracts the words in between the "< > " ?
I am doing this with a stream and I know you can get it with the .map() function but I cannot figure out how to do it.
Please find below java code to do so:
import java.io.IOException; import java.nio.file.Files; import java.nio.file.Paths; import java.util.stream.Stream; public class Main { public static void main(String[] args) throws IOException { String filename = "/home/beenoo/HomeworkLib/text.txt"; Stream<String> stringStream = Files.lines(Paths.get(filename)) .map(input -> input.substring(input.indexOf("<") + 1, input.lastIndexOf(">"))); stringStream.forEach(System.out::println); } }

I need help parsing a large text file in order to create a map using Java. I have a text file named weather_report.txt which is filled with hundreds of different indexes. For example: one line is "POMONA SUNNY 49 29 46 NE3 30.46F". There are a few hundred more indexes like that line with different values in the text file and they are not delimited by commas but instead by spaces. Therefore, in this list of indexes we only care...
Programming language --> Matlab The name of a text file Outputs: (cell) An Nx2 cell array listing words and their counts in sorted order Function Description: Have you ever seen those fancy word-clouds based on the frequency of word occurrences in some text? Well the first step of making a graphic like that is to figure out how often the words in some text occur, which is exactly what this function will do. You will count the number of occurrences...

JAVA Code: Complete the program that reads from a text file and counts the occurrence of each letter of the English alphabet. The given code already opens a specified text file and reads in the text one line at a time to a temporary String. Your task is to go through that String and count the occurrence of the letters and then print out the final tally of each letter (i.e., how many 'a's?, how many 'b's?, etc.) You can...

QUESTION The ReadFile class opens and reads a text file. The WriteFile class opens and writes to a file. Compile and run these programs. There are several ways to read/write text files. The examples shown here are just one way of achieving this. Look at the API for the BufferedReader class. The readline() method is a simple way to read the text file line by line. It returns null when the end of the file has been reached. https://docs.oracle.com/javase/8/docs/api/java/io/BufferedReader.html Look...
