Yes its big exception because compiler confused it happily compiles default concrete methods but in print() it collapse

[devkawde]

1)it won’t give Exception, will give Compile time error
2)For happy path we need to override print () method and if u want to call First interface method then add First.super.print()
3) if u want to call Second interface method then add Second.super.print

[prakashp]

We will get an exception Unrelated defaults for print() from types first and second

[reshmaranjan]

Exception. Because interfaces only have abstract type methods not body as shown in picture. It should have been like this:
Interface first {
default void print();
}
Interface second {
default void print();
}
That's it.

C) Exception. Both method have same method name, compiler will confuse which method excute first

[ItsTheTime]

Exception, inerface should have public methods

[thepositivesoch]

Exception to overrid the anyone default method to the chield class eithr from test1 or test2

[Jai-czph]

We must override all the methods() in interface in child class

[lateefadedokun]

Exception, Because interface can only container unimplemented method ().

[DipakChavan-tf]

Exception becouse it will give a ambiguity error

[_JackTheRipper]

Ans: Exception

If test.First.print() -> First

[arekuti]

since both interface have same method signature "print()"
we are getting exception
if we change method signature for any of the interface it will work
print() - First
print(String str) - second

[anujapopale]

Exception is the right ans. Bcz interface can only decalre methods, methods without body.
