Java 8 lambda predicate chaining?

Question

I can\'t get it to compile, is it even possible to chain predicate lambdas?

Arrays.asList(\"1\",\"2\",\"3\").stream().filter( (e -> e==\"1\" ).or(e-> e         


        

Answer 1

Predicate pred1 =  "1"::equals;
Predicate pred2 =  "2"::equals;

public void tester(){
      Arrays.asList("1","2","3").stream().filter(pred1.or(pred2)).count();
}

You can move your separate your conditions to make it possible to recombine them other ways.
