How to set java path in Windows-10

Java / javac is not an internal or external command error will face when we didn't set java installation path properly. Here are the different ways to set the java path.

Set java path: When java installation completes, it will creates two sub directories under the top directory of Java. These two sub directories are jdk_version and jre_version.

For ex: you have installed JDK, in program files directory in your local directory the directory will generate with the name of JDK_<Version>. In JDK directory that can create the list of folders. Like bin, jre, etc. There are 2 types are there to set the java path:

  1. By using the Command Prompt (Temporary)
  2. By placing in the MyComputer (permanent)
1.Temporary Path:         First select the bin path under the jdk/jre directory. Follow these instructions.
Start Menu ---> click on Run ---> type cmd, click on enter ---> C:/set path=c:\j2sdk1.6.07_01\bin;

 2.Permanent Path:         First select the bin folder under the jdk/jre directory. Follow these instructions.
Right click on MyComputer ---> go to Properties ---> Advanced --->Environment Variables ---> in System Variables ---> path ---> edit/new ---> Path: c:\jdk1.6.07_01\bin.

 In User Variables ---> Classpath ---> edit/new ---> Class path: c:\jre1.6.07_01\lib;

 Note: In above, System/User variables path/Classpath is already available in that time you can choose only "Edit" button. If that are not there in that list you can select the "New" button and set name as well as path.

 How to check your setting java path working perfectly or not?          Open the Command Prompt (CMD), write java (or) javac click ENTER button. That will display the list of commands on the command prompt. You will get the below exception when you didn’t set the java path properly.
For Ex: javac / java is not an internal or external command
Note: You’re setting the path through the Command prompt, which is not permanent. That can be useful for before shooting down your Computer. Once you restated/shooting down your computer that java never works, that needs to set path once again.

 You’re setting the path in MyComputer that is permanently placed. Once you will set java path in environment variables that will be the permanent.

 How to set the Java path in Windows 8 / 10?        
Open START (or) press windows button ---> Choose Control Panel ---> choose System option ---> choose advanced tab ---> Environment Variables

 ---> In System Variables ---> path ---> edit/new ---> Path: c:\jdk1.6.07_01\bin;

 ---> In User Variables ---> Classpath ---> edit/new ---> Class Path: c:\jre1.6.07_01\lib;

Prime, Fibonacci and Factorial number with example in java

Prime number, Fibonacci series and Factorial number programs are most commonly asked questions in interview. Read this article to know what is and how to write programs for prime number, fibonacci series and factorial number. Prime Number: prime number is natural number greater than 1 that has no positive divisor other than 1 and itself. A natural number greater than 1 is not a prime number, is called Composite number . For example, 7 is a prime number. Because it can divide with 1 and 7 only. Where as 8 is composite number. Since it has the divisor 2 and 4 in addition to the 1 and 8. The below example represents the finding the passing number is prime number or not.

JVM, JRE and JDK in Java

JVM, JRE and JDK are the most basic common concepts to know in java. These are the basic features to understand how Java architecture works? JVM stands for Java Virtual Machine, which doesn't have any physical directories created in java installation. JRE stands for Java Runtime Environment, which creates the directory under Java installation path and also present in JDK. JDK stands for Java Development Kit, which creates the directory in Java installation path and also it has it's own JRE. Since we have already learn that Java is platform independent means if we have implemented any of the java class in one environment, it will be executed in any other environment and provides the same output. But, JVM, JRE and JDK all are platform dependent . So that, for windows, linux, unix, mac, solaris..etc has it's own JVM, JRE and JDK. One will be not compatible with other environments. While installing the Java, we might come to know a bit about JRE and JDK. But, JVM is the other...
