Java Installation: Downloading, Installing and Setting Path

Course- Java >

In this tutorial we will learn how to download and install
Java and then setting path to make Java programs run.

Downloading and Installing

  • Select Accept License
    Agreement
    and then download appropriate version for your operating system.
  • After downloading, install the JDK.
  • If installation is done properly you can see two files java and javac by going to C:Program FilesJavajdk1.7.0_60bin.

 

How to set Java path?

To make java programs compile and run you have to set the
path of java compiler. You can set java path in two ways: temporary and
permanent.

Temporary Java path setting

  • Copy the path of bin folder by going to jdk/bin i.e. C:Program
    FilesJavajdk1.7.0_60bin
    . Here jdk1.7.0_60 (will vary according to jdk version).
  • Open command prompt and write set path=C:Program FilesJavajdk1.7.0_60bin and then press enter.
  • This method will work only one time. After closing cmd you
    have to repeat the same process again.

Permanent Java path setting

  • Right click on Computer
    and then select Properties.
  • Then goto Advanced
    tab and click on Environment Variables.
  • Now click on new
    and then in variable name field write path and
    in value field write the path of bin folder i.e. C:Program FilesJavajdk1.7.0_60bin

 

  • Click ok to save settings. You have done!
  • This will permanently set the path and you can run programs
    whenever you want.

Check path setting was properly or not

  • You can confirm whether the path setting was properly or
    not. Just open cmd again, write javac
    and press enter.
  • If it will show details about the java compiler then it is ok.
  • If it will show and
    error like ‘javac’ is not recognized as
    an internal or external command
    then you have done something wrong. Check
    the whole process again.
