Why does it always give an error when compiling a java application?

Question

Java

This is the output when compiling on the command line:
Hello.java:1: error: error while writing Hello: Hello.class
public class Hello {
^
1 error
Here is the program code itself:
public class Hello {
public static void main(String[] args) {
System.out.println("HelloWorld!");
}
}
It seems like everything is simple. On the Internet they write that most likely there is no access due to win7. But even if so, how to open access and why?

Answer 1

I solved it by getting admin rights

Answer 2

I'm not an expert, but maybe there is an "invisible character", the same BOM mark, try resaving the file in utf8-8 without BOM

Answer 3

jdk found? Are the paths correct? Recheck.

Answer 4

Google did not look? Searching through the text of your error suggests that you probably saved the .java file in the Program Files folder (for example, in C:\Program Fiels\Java\jdk1.7.0\bin), in which Windows by default prohibits creation and modification files

Answer 5

Move the file. For example, along the path C:\Users\Java\ .
