I can't open javac, but I do the steps from the app. Why?

Question

problems

Answer 1

@Ace Yes... both missing path and installation throw 'unknown command' if javac is executed by console.

Answer 2

@Ace But then console throws an error.

Answer 3

Then the .java files should have been successfully compiled to .class by javac. Did you try to start your program (command: java YourMainFile)?

Answer 4

I meant to run your program (the class which contains your main method) from console, sry.

Answer 5

Could you please post the error message?

Answer 6

Answer 7

I don't know, you mean that java Start as a main file? and I can't give cmd commands

Answer 8

Now I have to install it new? and what I had missing in part 2? I need to changing something?

Answer 9

And what is IDE @Ace?

Answer 10

I used notepad++ but that's isn't my problem.. I'll try to install Javascript new and I hope than I can see the mistake
thanks for the help!

Answer 11

javac is for java not javascript
javac is to compile java sourcecode hence the "c"
if it doesnt work check your PATH
else redownload jdk

Answer 12

check whether u have installed the app and also check if have installed then your .java file is in that driver as cmd working field might be different it means drive switching u have done or not means u file is in d: drive and u try to compile in c: drive .so u have to switch th drive first of all any then try.
