How to use regular expressions to match strings in Java?

Concept

1. Various Match operations can be used to determine whether a given Predicate meets the elements of a Stream.

2. The Match operation is a terminal operation and returns a Boolean value.

Example

boolean anyStartsWithA =
    stringCollection
        .stream()
        .anyMatch((s) -> s.startsWith("a"));
 
System.out.println(anyStartsWithA);      // true
 
boolean allStartsWithA =
    stringCollection
        .stream()
        .allMatch((s) -> s.startsWith("a"));
 
System.out.println(allStartsWithA);      // false
 
boolean noneStartsWithZ =
    stringCollection
        .stream()
        .noneMatch((s) -> s.startsWith("z"));
 
System.out.println(noneStartsWithZ);      // true
