+
+Check Java version
+```bash
+java --version
+javac --version
+```
+
+Install [Maven](https://maven.apache.org/install.html)
+```bash
+mkdir -p ~/devtools/apache
+cd ~/devtools/apache
+wget https://dlcdn.apache.org/maven/maven-3/3.9.9/binaries/apache-maven-3.9.9-bin.tar.gz
+tar xvf apache-maven-3.9.9-bin.tar.gz
+```
+
+Set $PATH
+```bash
+export PATH=$PATH:~/devtools/apache/apache-maven-3.9.9/bin
+mvn -v
+```
+
+Install JDBC example
+```bash
+mkdir -p ~/github/mkyong/
+cd ~/github/mkyong/
+git clone https://github.com/mkyong/java-jdbc/
+```
+
+Build the Jarfile of the program
+```bash
+cd ~/github/mkyong/
+cd java-jdbc/postgresql
+mvn install
+```
+
+
+Check the classpath of the program
+```bash
+APP_CLASSPATH=$(mvn -q exec:exec -Dexec.executable=echo -Dexec.args="%classpath")
+echo $APP_CLASSPATH
+```
+
+Run the program `src/main/java/com/mkyong/jdbc/JDBCExample.java`
+```bash
+MAIN_CLASS=com.mkyong.jdbc.JDBCExample
+mvn -q exec:java -Dexec.mainClass=$MAIN_CLASS
+```
+or
+```bash
+java -cp $APP_CLASSPATH $MAIN_CLASS
+```
+
+
+Run the program `src/main/java/com/mkyong/jdbc/JDBCExample2.java`
+```bash
+MAIN_CLASS=com.mkyong.jdbc.JDBCExample2
+mvn -q exec:java -Dexec.mainClass=$MAIN_CLASS 
+```
+or
+```bash
+java -cp $APP_CLASSPATH $MAIN_CLASS
+```
+
+Run the program `src/main/java/com/mkyong/jdbc/TransactionExample.java`

+mvn -q exec:java -Dexec.mainClass=$MAIN_CLASS 
+```
+or
+```bash
+java -cp $APP_CLASSPATH $MAIN_CLASS
+```
+
+## Extra: JDBC URL
+
+Modify the URL `"jdbc:postgresql://127.0.0.1:5432/test"` into the Java classes
+
+```
+tree src/main/java/com/mkyong/jdbc/
+grep -r -n "jdbc:postgresql://127.0.0.1:5432/test" src/main/java/com/mkyong/jdbc/
+```
+
+## Extra: Mise à jour des dépendances du projet
+
+```bash
+mvn versions:display-dependency-updates
+mvn versions:display-plugin-updates
+```
+
+Modifiez la propriété `postgresql.version` dans le `pom.xml` pour mettre à jour le [driver JDBC PostgreSQL](https://mvnrepository.com/artifact/org.postgresql/postgresql). La dernière version (sans vulnérabilité connue) est la version `42.7.4` au 08/11/2024.
+
+```bash
+mvn versions:use-latest-releases
+mvn versions:update-properties
+git diff pom.xml
+```
