For general Java programming the Eclipse Classic would be appropriate. If you want to do web development, then I suggest the Java EE variant, which is suitable for JSP (it also contains everything the Classic variant does). Pick "Eclipse IDE for Java Developers" for now. It does everything except JSPs.
However, Eclipse does not need the JDK to be formally "installed" to use it. It is enough to copy the JDK folder onto the computer you want to run Eclipse on. Before you start, make sure you download the JDK with the same bitness as the Eclipse version you downloaded. 64-bit Eclipse needs a 64-bit JDK.
You no need to install JRE then , JDK usually consists of both development & run-time environments in it. If you install JDK then JRE will be in it and installed automatically along with JDK. generally to do javac <filename.java> you need to have JDK which already have JRE in it.
Current releases of Eclipse require Java 8 or newer. If you are using Eclipse to do Java development, or are on macOS, install a JDK. In all cases, 64-bit Eclipse requires a 64-bit JVM, and a 32-bit Eclipse requires a 32-bit JVM.
Here is the complete sequence in Eclipse Luna:
- Right click your project > properties.
- Select “Java Build Path” on left, then “JRE System Library”, click Edit…
- Select "Workspace Default JRE"
- Click "Installed JREs"
- If you see JRE you want in the list select it (selecting a JDK is OK too)
class files. Without JDK, you can not create Java applications and programs. By the way, JDK comes with its own JRE, but when you run Java program using java command, the JRE which comes first in System PATH is used for execution.
You no need to install JRE then , JDK usually consists of both development & run-time environments in it. If you install JDK then JRE will be in it and installed automatically along with JDK. generally to do javac <filename.java> you need to have JDK which already have JRE in it. to do java filename you need only JRE.
JDK is for development purpose whereas JRE is for running the java programs. JDK and JRE both contains JVM so that we can run our java program. JVM is the heart of java programming language and provides platform independence.
Oracle only requires an account (sign-in) to download older versions of Java that are no longer available to the public (archived). You can download publicly available versions of Java without signing in; however, you still have to accept the license agreement beforehand.
First try it in your command prompt as “set path=C:Program FilesJavajdk(version)in” ,then type “javac” in prompt if it starts showing bunch of files ,then it is installed.
