• Requirements before running codes:

  • Install an IDE that compiles and runs Java codes. Recommendation VS Code
  • How to setup WSL Ubuntu terminal shell and run it from Visual Studio Code: visit: https://www.youtube.com/watch?v=fp45HpZuhS8&t=112s
  • How to Install Java JDK 17 on Windows 11: https://www.youtube.com/watch?v=ykAhL1IoQUM&t=136s

  • Installing Oracle JDK on Windows subsystem for Linux.

    • Run WSL as Administrator
    • set -ex
    • NB: Update links for other JDK Versions
    • export JDK_URL=http://download.oracle.com/otn-pub/java/jdk/8u131-b11/d54c1d3a095b4ff2b6607d096fa80163/jdk-8u131-linux-x64.tar.gz
    • export UNLIMITED_STRENGTH_URL=http://download.oracle.com/otn-pub/java/jce/8/jce_policy-8.zip
    • wget --no-cookies --header "Cookie: oraclelicense=accept-securebackup-cookie" ${JDK_URL}
    • Extract the archive: tar -xzvf jdk-*.tar.gz
    • Clean up the tar: rm -fr jdk-*.tar.gz
    • Make the jvm dir: sudo mkdir -p /usr/lib/jvm
    • Move the server jre: sudo mv jdk1.8* /usr/lib/jvm/oracle_jdk8
    • Install unlimited strength policy: wget --no-cookies --header "Cookie: oraclelicense=accept-securebackup-cookie" ${UNLIMITED_STRENGTH_URL}
    • unzip jce_policy-8.zip
    • mv UnlimitedJCEPolicyJDK8/local_policy.jar /usr/lib/jvm/oracle_jdk8/jre/lib/security/
    • mv UnlimitedJCEPolicyJDK8/US_export_policy.jar /usr/lib/jvm/oracle_jdk8/jre/lib/security/
    • sudo update-alternatives --install /usr/bin/java java /usr/lib/jvm/oracle_jdk8/jre/bin/java 2000
    • sudo update-alternatives --install /usr/bin/javac javac /usr/lib/jvm/oracle_jdk8/bin/javac 2000
    • sudo echo "export J2SDKDIR=/usr/lib/jvm/oracle_jdk8 export J2REDIR=/usr/lib/jvm/oracle_jdk8/jre export PATH=$PATH:/usr/lib/jvm/oracle_jdk8/bin:/usr/lib/jvm/oracle_jdk8/db/bin:/usr/lib/jvm/oracle_jdk8/jre/bin export JAVA_HOME=/usr/lib/jvm/oracle_jdk8 export DERBY_HOME=/usr/lib/jvm/oracle_jdk8/db" | sudo tee -a /etc/profile.d/oraclejdk.sh

• About Codes:

  • The codes are all written by myself only
  • I hard code them as part of my practice code, practical and assignemnts for my coding modules.

• About Me:

  • Tebogo Sello Selepe
  • Computer Sciences at Tuks

Makefile

NB: A makefile Is Included to compile and run the codes on the terminal with the following commands:=

• make clean
• make
• make run

default:
	javac *.java

run:
	java Main

clean:
	rm -f *.class
	reset
	clear

tar:
	tar -cvz *.* -f Java_Filename.tar.gz
	
untar:
	tar -zxvf *.tar.gz
