Installing JDK and Eclipse -JDKeclipse.ppsx
- 1. Installing JDK and eclipse
- 2. Start!!?? Java is a simple programming language. Writing compiling and debugging a program is easy in java.
- 3. Start programming with java Install JDK (java development kit) Install eclips (IDE)
- 4. What is JDK & eclips? JDK enables us to develop and run a java program Eclips is the environment where we write the codes
- 11. Eclips Just unzip the eclips file Right click the zip file and Select extract all
- 12. Open the extracted file Click this icon
- 13. Eclips environment Created packages and classes are here Write codes here Display the result here
- 14. Write the first code inside eclips public class FirstExample { public static void main(String args[]){ System.out.println("I am a student "); } }
- 15. Learn More about JDK
- 16. JDK (java development kit) is a software development environment used for developing Java applications and applets. It is a superset of a JRE and javac compiler.
- 18. Compiler (javac) A compiler is a computer program that transforms source code written in a programming language into another computer language. Java source code Bytecode Compiler
- 19. JRE (Java Runtime Environment) JVM(Java Virtual Machine) = interpreter A (JVM), interprets compiled (bytecode) for a computer's processor (hardware) JVM JRE
- 20. Let’s practice how it works!!!
- 21. Running java code/source code via CMD
- 22. Make sure if javac (java compiler) is exist. Run CMD and write these commands and click enter
- 23. The result should be as the following picture So You have java compiler!! This is the directory where the java compiler is located
- 24. Define the java compiler directory path 1- Open System properties 2- Go to Advanced tab 3- Click ‘Environment variables’ 4- Under ‘System Variables’ scroll down to find PATH. Edit the entry and add JDK path. 5- Click OK and close the windows. Note: you can copy the compiler directory in the previews picture and paste it to variable value.
- 25. Change the directory. Here the source code is located on desktop. Compile the source file via java compiler(javac) Run the compiled file via jvm Display the result/ output Run test.java program in CMD
