Example1
interface NumericTest { boolean computeTest(int n); } public static void main(String args[]) { NumericTest isEven = (n) -> (n % 2) == 0; NumericTest isNegative = (n) -> (n < 0); // Output: false System.out.println(isEven.computeTest(5)); // Output: true System.out.println(isNegative.computeTest(-5)); }
