Issue
How can I use the following Predicate?
Predicate<Integer> isOdd = n -> n % 2 != 0;
My try:
System.out.println(isOdd(5));
Compiler output:
java: cannot find symbol
symbol: method isOdd(int)
location: class Main
Solution
To invoke a Predicate
, use the method called test
.
System.out.println(isOdd.test(5));
or
if(isOdd.test(5)){
// Do something fun
}
This is documented here
