the problem is that I upgraded to Windows 10 and now I'm installing my tools to programming and now that I installed the JDK 7 of Java, when I try to use in the cmd the command:
The result of this is: "javac" is not recognized as an internal or external command...
But I was edited the PATH with the correct link of jdk, because when I use "java", it is ok.
Now, I tryed in the console with this command:
java is part of the JRE, not the JDK.
You need to add the JDK bin to the system PATH, in Control Panel, System, Advanced, Environment Variables.
