IDEs have builtin Git support, but command line is sometimes better.īook is easy to read and covers a lot. The “git” command line program is needed to submit some assignments.

The IDE (Eclipse, BlueJ, Netbeans) can show context sensitive help using the API docs on your computer.

#BLUEJ JAVA DEVELOPMENT KIT INSTALL#

You can view the JDK Documentation online at, but its much faster to install on your computer and bookmark it.Please install on your computer and bookmark the API docs in your browser (demo in class).

#BLUEJ JAVA DEVELOPMENT KIT FREE#

There is also a “Community Edition” that is free for everyone. The “professional” edition has a free Student License.

#BLUEJ JAVA DEVELOPMENT KIT CODE#

You can interactively run code without compiling, view objects, and visualize project structure. Please try BlueJ, but you can use whatever IDE you prefer.

Good: c:\java\jdk8u144 (Windows), /opt/java/jdk8u144 (Linux).īad: c:\Program Files\Java Development Kit\jdk_1.8.0u144 Programming Tools You NeedīlueJ (IDE) for Windows and Mac OSX includes the Java JDK. To avoid path problems and for convenience adding new versions of the JDK, you should install Java in a short path without spaces. Please install the JDK and JDK docs in a path without spaces JRE does not have abilities to compile the java program, it just provide the environment to execute the byte code.

Java development kit also provides the tool to compile the java program as well as the Environment to execute the java program. I hope you are now clear with the difference. Actually in simple words, JRE is a subset of JDK or if JDK is a country than JRE is the state in that country. There is not much difference between two. JDK can be defined as java development kit and JRE as java runtime environment. Similarly in simple words, IDE (Integrated Development Environment) which is used to write the java program and saves a lot of effort for the programmer by using shortcuts and in built functionality. So to make it simple, you can compare it to your school time copy or registers where you use them to write down the school topics or notes. Most of us get confused when we heard the term IDE, what the hell is that, where it come from. So it is better to understand jre like a governing body(BCCI, FIFA, FA, NFL, NBA) which provides the compiled code (byte code ) all the necessary things (ground,audience,playing kit etc ) so that it can successfully execute the program. If you extract the rt.jar then you will find the six packages in it, namely , You can find the rt.jar here in your computerĬ:\Program Files\Java\jre1.7.0\lib ( for windows user ) Rt.jar where rt extends for runtime that is the class files which are ready to be executed in the java runtime environment. The classes which are prebuilt or that are provided by the java originator, are placed in one jar called rt.jar. class extension file is then executed in different environments to generate the output. class extension file also generated which is in the byte code format or the machine understanding format. Whenever we compile a java program, then a.

Program -> Byte Code -> Execute(.class file) So whenever you think of compiler then think it as a doctor who is there to improve your program and make it free from syntax errors. We need to understand compiler as a doctor which tells the patient (here java program )that where the problem lies, if there is clearance from the doctor (compiler) then the patient(java program) is free to execute in any environment. There are predefined conditions which need to be implemented in order to not to get a error from the java compiler
