How to detect file location in Java Classes?

Question

Lets take a class A.

class A{
 
  public getAbsoluteLocation(){
    
   ....
  }
}

How can this class know in which directory it is located?

Yes but most likely getAbsoluteLocation() should be a string and should return its corresponding datatype. — Temidayo Dtuzzy Omotayo, Sep 04 '20 at 05:53

It isn't necessarily located in a filesystem directory at all. More likely a JAR or WAR or EAR file. — user207421, Sep 04 '20 at 05:58
@VladislavVarslavans No it doesn't. That gives you the location of the JAR file, not of the current class. — user207421, Sep 04 '20 at 05:58
class can have no file, it can be downloaded over network or even generated dynamically. — Alexei Kaigorodov, Sep 04 '20 at 08:02

Assumption is that you just want to print the path. You can also return the value or perform any other operations based on your method return type.

class A {
 
  public void getAbsoluteLocation() {
    ClassLoader loader = A.class.getClassLoader();
    System.out.println(A.class.getResource("A.class"));
  }

}
