o    Variable name = JAVA_HOME
o    Value =  C:\Program Files\Java\jdk1.8.0_65(path depends on the drive in which java installed)
v  add the JAVA_HOME variable path in the system PATH variable
§  PATH = %JAVA_HOMOE%\bin
v  Go to the command prompt and validate the JDK version c:\java – version it must show the JDK version.
v  That’s it! ,Java installation is done successfully.
Step2:
v  Install the Maven software
v  Create the system Variable : (Right click on My Computer à Properties à Advanced system settings àSystem Properties window will get displayed àUnder Advanced à Environment VariablesàSystem VariableàNewàEnter the Variable name and Variable value)
o    Variable name = MAVEN_HOME

v  add the MAVEN_HOME variable path in the system PATH variable
§  PATH = %MAVEN_HOMOE%\bin
v  Go to the command prompt and validate the Maven version c:\mvn – version it must show the MVN version.
