As we have always learnt, a Java class can never extend/inherit more than one class. While this still holds true, very few of us know that a Java "Interface" is capable of extending/inheriting more than one "interfaces".
For example:
interface interface_1{
// interface definition
}
interface interface_2{
// interface 2 definition
}
/// and then
interface A extends interface_1, interface2 {
}
For example:
interface interface_1{
// interface definition
}
interface interface_2{
// interface 2 definition
}
/// and then
interface A extends interface_1, interface2 {
}
So, this is a valid interface inheritance in Java. Note that this holds true only in the Interfaces and not Java classes
