Since a few years I am in C# but I wanted to try out java for this challenge.

Technologies and Libraries

package manager: gradle

I am using following libraries as support

• command line tool:
  • info.picocli:picocli

Install and run

Build

I use gradle version 7.3 and this is related to java 17 using OpenJDK

• checkout comp matrix https://docs.gradle.org/current/userguide/compatibility.html

you need to start folder "no-1" as your main folder (not in the parent folder)

./gradlew clean installDist

Run

without any parameter you will see the help information

./wc.sh
Missing required parameter: '<file>'
Usage: ccwc [-chlVw] <file>
counts the number for lines, words, characters
<file>      The file to calculate for.
-c              -c for counting characters
-h, --help      Show this help message and exit.
-l              -l for counting lines
-V, --version   Print version information and exit.
-w              -l for counting words

Run on a test file

Open 3 terminals and start in each

./wc.sh app/src/test/resources/text.txt

./wc.sh -l app/src/test/resources/text.txt
