[aditirajendran]

Sir ur vids are awesome..I have two doubts which i hope u would help..
1.sir u told FUCTIONAL INTERFACES ARE SINGLE ABSTRACT METHOD INTERFACES,
but BinaryOperarator interface has 2 methods but it is also a fuctional interface
2. sir u told we can define a method in an interface using default keyword
but BinaryOperarator interface has defined methods with "public static" modifiers...
pls help me sir, i am struck at this point...

I would appreciate your attempt but it seems there are some things to be corrected. for example, reduce will not an int always, it purely depends on the the type of the first argument you are passing to reduce method, It can be any type

[rajeshg]

Here is the simple example where it takes String as the first param in the reduce method and it returns a String
public class StreamsReduceExample {

public static void main(String[] args) {
List<String> strings = Arrays.asList(" Hi", "Hello", " How are you?");
String result = strings
.stream()
.reduce("Add me first ", (tempResult, element) -> tempResult.concat(element));
System.out.println(result);
}

}
