ERROR - A default method cannot override a method from java.lang.Object

Error

"A default method cannot override a method from java.lang.Object" while using Default Method in Java 8.

Error Type

Compile Time ( Java 8 )

Sample Code

public interface DefaultMethodInterface {
    static public void toString(){
        System.out.println("DefaultMethodInterface");
    }
}
   
Cause

The specified Default method has the same name and signature as of Object Class method. We cannot override a Object Class method with the default method in Interface.  

Resolution

Change the Name of the default method or remove it.

public interface DefaultMethodInterface {
    static public void string(){
        System.out.println("DefaultMethodInterface");
    }
}

Why is it forbidden to override an Object Class method with Default Methods ?
