Sorted sorting method in java

Explanation

1. Sorted is also an intermediate operation, and the parameter returned is a Stream. Likewise, we can pass in a Comparator that defines the ordering, and if none is passed, the default ordering is used.

2. sorted will not make any changes to stringCollection. stringCollection is the original elements, the order is unchanged.

Example

stringCollection
    .stream()
    .sorted()
    .filter((s) -> s.startsWith("a"))
    .forEach(System.out::println);
 
// "aaa1", "aaa2"
 
System.out.println(stringCollection);
// ddd2, aaa2, bbb1, aaa1, bbb3, ccc, bbb2, ddd1
