Example1 - Numeric Test

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));
}
