How to Install Java JDK and Set Environment Variables Path
Here we will see how to Install JAVA JDK and Set the Environment Variables Path for JAVA programs. If you are JAVA programmer then it is important to set the JAVA Environmental Variable path.That is we just give reference to the JAVA JDK to Windows like if we are Compiling and Running the Program from Command Prompt. So it is must, to set it before you run your program.
Step 1: Downloading and Installing JAVA JDK
- Download the JAVA JDK that is JAVA SE(Standard Edition) From Here.
You can choose your JAVA JDK version architecture whether it should be 32bit (x86) or 64bit (x64). But I recommend 32bit to Download.Can be downloaded By clicking on “Java Platform (JDK) 7uxx (or Version)” Here we are downloading only JAVA JDK without NetBeans.
- Now download by Accepting License Agreement. Here I am downloading Windows x86 Version. Filename isjdk-7u25-windows-i586.exe .
- Now after Downloading Install the JAVA JDK with Preferred Install option.

Java SE Runtime Environment 8 Downloads:
Do you want to run Java™ programs, or do you want to develop Java programs? If you want to run Java programs, but not develop them, download the Java Runtime Environment, or JRE™.
If you want to develop applications for Java, download the Java Development Kit, or JDK™. The JDK includes the JRE, so you do not have to download both separately.

Step 2: Setting up Environment Variables or Path
Now after Downloading and Installing the JAVA JDK lets set up the Environment Variables/Path.

- Open Your my Computer.
- Goto System Properties.
- Open Advance system settings
Step 3:
I currently have the latest JRE 32 bit installed on my 64 bit machine. This is the version I was recommended when I went to the download page for the first time. I suspect this was because I was running 32 bit Chrome and from what I understand it is important that the JRE version corresponds to the flavor of the browser you are using (bit wise). I also have 64 bit IE on my machine, but I hardly ever use it, so I didn't do an additional install of the 64 bit JRE, as suggested here: https://www.java.com/en/download/faq/java_win64bit.xml
Now I want to install Eclipse Epsilon and I am unsure if I should go for the 32 or the 64 bit version. Do I have to go with 32 bit because I have JRE 32 bit installed? What if I install JDK 64 bit? Should I go for 64 bit with Eclipse also in that case? Here Java and Eclipse - 32 vs. 64bit the conclusion was that I should install the bit flavor of Eclipse corresponding to the JRE version I have on my machine. But I've read in another post that the JRE just runs the bytecode and it doesn't matter if it was generated by a 32 or 64 bit compiler - it will run it correctly anyway. Am I right then in my understanding that Eclipse should be the same bit flavor as the JDK (if installed on the machine) or as the JRE otherwise? I've even read somewhere that I won't even need the JRE if I install the JDK, since it comes with several JREs.
Do some Eclipse versions come with JDK?
I need to install Eclipse Epsilon (Eugenia, Xtext) for my current coursework and it only requires JRE and not JDK. What would be your suggestion in this case? What about the long run?
What if I install Chrome 64 bit instead? Since I would be running only 64 bit browsers on my 64 bit machine I suspect I would then only need JRE or JDK 64 bit and Eclipse 64 bit.
This might sound really silly, but what about source code that I might receive from other sources (written/precompiled in a 32 bit environment) - would I have any problems handling it?
I want to make sure I get this right, so as to not have doubts again in the future. Thank you!
