Hi All,
As we all know java is not complete OOps language the reason
behind this is java does not support multiple inheritance,
to avoid this draw back of java sun introduce interface
alomg with few new concept.

So 110% sure that we can implements and we can extends as
well more than one interface.

Scenarios:
1) in term of subclass

interface i1{
void mi1();
}
interface i2{
void mi2();
}

now

Case 1:

public class MultipleImplements implements i1,i2{
// now here we need t implement all methods available in i1
and i2 (restricted)

public void mi1(){
System.out.println("Interface i1 mthod");
}
public void mi2(){
System.out.println("Interface i2 mthod");
}
}

Case 2:

interface i3 extends i1,i2{
// here use can define more method and you can not over ride
i1 and i2 method because you can not method body in interface so
String mi3();
}

Conclusion: 110% you can extend and implement more than one
interface
