Why javac does not find this Java file?

[Rashid Mian]

Here is the director structor I am using to compile a java sourse

1- C:\src\b\A.java
2- C:\classes

  package b;
  public class A {
  public static void main(String[] args)  {
    System.out.println("ABC");
  }
}  

when I use the following command to compile A.java I does not find it.

C:\>javac -sourcepath src -d classes A.java
OR
C:\>javac -sourcepath src -d classes b/A.java
Why it can't find that source file?
What I want is it to find source file using above position only, Means I don't want to go to src folder like this

C:\src>javac b/A.java -d ..\classes

Source path is used to tell the compiler where to find sources it needs that aren't specified on the command line.

I did not understand it, please give me example in my context

In the example you quoted , sourcepath doesn't have any role as it is not referring to any other java files.

If A.java have any reference to other java file which is placed in some other directory, we can use sourcepath to specifiy where to find the referenced file.


for eg:

   
 package b;
 
 import second.Test;
 
 public class A { 
 
 public static void main(String[] args)  {  
  System.out.println("ABC");  
  Test t = new Test();
  }
  
  
 }  

Here A.java is referencing Test class which is located in C:\src\second\Test.java. We can compile A.java file using the command

C:\src>javac -sourcepath . b\A.java
