necessary to set path for java?

Question

I already installed java in pc, and I am using eclipse for coding.

My question is that, is it necessary to set the java path. because eclipse detect java automatically.

I think for eclipse there is no need to set java path. we can work directly.

Can anyone tell me proper answer for this.

Is it necessary or not to set the java path?

Whats seems to be the actual problem? Is your project building or not? Are you, perhaps, confusing java path and classpath? — Maxim Kumpan

Depends, if all java apps you are using are "detecting", you are ok not setting it; if you need command-line support (i.e. directly type java ... or javac ...), you will need to do some PATH setup — user180100

If you use some IDEs for writing code and compile it, NO. They automatically(or manually) detects where the jdk is installed.

But if you want to compile the application from command line(eq: javac, maven, ant) then you need to set the env path.

Well, it's strongly advisable to set JAVA_HOME.

If Eclipse finds your JDK - it's ok. But if you're using some other Java technologies (like MAVEN, ANT, JBoss, Tomcat etc.) - they require JAVA_HOME to be set.

So, I strongly advice you to do that :)

P.S. And also to add JDK's bin directory to your PATH - in order to use java or javac command from the command line.

It's not necessary to set the java path. Eclipse already covers that for you.

not necessary if you just want to run and compile in eclipse. However if you want to run and compile in command prompt then its necessary to set path
