• Just open up a command prompt and move to installation directory and type cd bin and check for java version by giving version-v as below.If the version is shown correctly there is no doubt that its installed perfectly

• Also take the command prompt and check for whether the java compiler is installed at the proper path by giving javac command as below

• This is because of missing of some of the settings.That means jdk installation path provided in the advanced system settings is wrong .Inorder to make it working properly just go to location C:\Program Files.

• In that location there should be a folder named java and inside that java folder there should be a file with jdk version as below(If its not there the installation is a failure one.)

• Then go and click jdk folder and go inside the bin folder and rightclick on any of the exe files inside the bin folder and check for properties as shown below

• This is where you should tell your java to look for your compiler.So Copy that path as shown below.

• Then Right click on My Computer and click on properties and then click on Advanced system settings as shown below

• Under Advanced system settings there is a section called environmental variables.Over there create a new variable called path and give the value as jdk path ie where jdk is(copied minits back)
