Cud u please help me understand this pls. As I understand to run a HelloWorld application program which prints HelloWorld on Console, I need JRE (WHICH COMES WITH JAVA.EXE) and so I can do java HellWorld and it runs HelloWorld.
As in other question, I understand that JRE is actually JVM..
Now without JRE, I cannnot do java HelloWorld..
but without JRE on my machine, I can run Applet HelloWorld because IE comes with JRE 1.3 .. so IE as well as Netscape has JVM in built for them but older version..
If I download JRE 1.4 on my machine.. and install it, so I can do java HelloWorld
but now applets in browser also runs with more recent version of JRE 1.4 (which i downloaded).
So now browsers are using JVM on my machine instead of their own JVM's?
Could somebody explain me what happened here? I downloaded JVM on my machine (JRE 1.4). Why are browsers are not using their own JVM's (1.3).
Am i understanding it correctly.. or am i missing something here.
Thanks for help,
