Syed Aziz Shah, Associate Professor at Coventry University's Research Centre for Intelligent Healthcare (CIH). With academic qualifications spanning across the UK, China, Sweden, and Pakistan – Syed brings over 12 years of experience in teaching, research and innovation. He is an interdisciplinary researcher focusing on advanced radio frequency (RF) sensor design and signal processing using RF and THz sensing, specifically for physiological measurements. He is highly motivated to utilize and develop advanced technologies that address the unmet healthcare challenges of unobtrusive monitoring for health and wellbeing purposes. With a proven track record of securing substantial research funding; notably, he secured research grants totaling £1 million (8 grants, 6 as PI and 2 as CoI.) and was honored with the UK’s prestigious Engineering and Physical Sciences Research Council (EPSRC) New Investigator Award for project ‘Radar Sensing for Human Activity Monitoring of Daily Living Simultaneously in Multiple Subjects’ (EP/W037076/1, £410,000 fEC)). He has also (co)-authored 110+ top-rank peer-reviewed journals and conferences including 3 transactions, indicating his dedication to advancing knowledge in the field of RF sensing. He has been leading the Healthcare Sensing Technology Research Group at Coventry University since 2020, overseeing two Assistant Professors, two Research Fellows, and eight PhD students, and having obtained extensive administrative experience. He provides strategic leadership, oversees postgraduate research activities, and offer mentorship to MSc and PhD students. He is actively involved in supporting PGR collaborations, maintaining ethical standards, managing PGR funds, and enhancing research impact within the research center and faculty. His research interests include RF sensing, telecommunications, 5G and beyond networks and use of technology in health careSyed Aziz Shah, Associate Professor at Coventry University's Research Centre for Intelligent Healthcare (CIH).

1. Introduction to JAVA

2. About Java Java is a powerful and versatile programming language for developing software running on mobile devices, desktop computers, and servers Developed by James Gosling in 1995 Popular because of write a program once and run it anywhere Java is a  programming language  and a  platform Platform : Any hardware or software environment in which a program runs, is known as a platform. Since Java has a runtime environment (JRE) and API, it is called a platform.

3. Types of Java Applications Four types of applications that can be created using Java programming Standalone Application Web Application Enterprise Application Mobile Application

4. JDK Editions Java Standard Edition (Java SE) Java Enterprise Edition (Java EE) Java Micro Edition (Java ME)

5. JDK Versions History of JDK version https://en.wikipedia.org/wiki/Java_version_history Latest is Java SE 18 [Java SE 18] Download from: https://www.oracle.com/java/technologies/downloads/#jdk18-windows

6. Installing Java To check if Java is installed (open command prompt and type following command) java –version Setting Java Path Temporary Path Open the command prompt Copy the path of the JDK/bin directory Write in command prompt: set path= copied_path Permanent Path using Environment Variables Settings

7. Environment Variable Go to "System Properties" (Can be found on Control Panel > System and Security > System > Advanced System Settings) Click on the "Environment variables" button under the "Advanced" tab Then, select the "Path" variable in System variables and click on the " Edit " button Click on the " New " button and add the path where Java is installed, followed by  \bin . By default, Java is installed in C:\Program Files\Java\jdk-15\bin Then, click "OK", and save the settings At last, open Command Prompt (cmd.exe) and type  java -version  to see if Java is running on your machine

8. Popular Java IDEs NetBeans Eclipse IntelliJ

9. JDK, JRE, and JVM Java Virtual Machine (JVM) Provides a platform-independent way of executing Java source code JVM comes with JIT(Just-in-Time) compiler that converts Java source code into low-level machine language Java Runtime Environment Set of software tools which are used for developing Java applications Contains JVM JRE = JVM + rt.jar ( lang , util , awt , swing, math packages) Java Development Tool kit (JDK) Software development environment which is used to develop Java applications Physically exists

10. JDK, JRE, and JVM

11. Interpreting/Compiling Source Code A program written in a high-level language is called a source program or source code A source program must be translated into machine code for execution

12. Compiling Source Code A compiler translates the entire source code into a machine-code file, and the machine-code file is then executed

13. Interpreting Source Code An interpreter reads one statement from the source code, translates it to the machine code or virtual machine code, and then executes it right away

14. Creating, Compiling, and Running Programs

15. Java Program Phases Phase 1: Creating a Program Phase 2: Compiling a Java Program into Bytecodes Bytecodes are re-executed by the JVM

16. Java Program Phases Phase 3: Loading a Program into Memory JVM class loader takes the .class file (along with associated class files provided by Java) and loads in memory

17. Java Program Phases Phase 4: Bytecode Verification Java enforces strong security to make sure that Java programs arriving over the network do not damage your files or your system (as computer viruses and worms might).

18. Java Program Phases Phase 5: Execution Interpreter JVM execute bytecode using interpreter (one bytecode at a time) which slows execution Just In Time(JIT) Compiler JVM analyzes the bytecodes as they’re interpreted searching for hot spots — parts of the bytecodes that execute frequently For these part JIT also known as Java HotSpot compiler Translates the bytecodes into the underlying computer’s machine language
