This example sorts the string array in a single line code usingStream. It uses theStream.sorted()method which helps in sorting a stream of objects in their natural order or according to the providedComparator. For reverse sorting the array, useComparator.reverseOrder(). // Unsorted string arra...
If the attempt to cast to fails for either or , you fall back on the trick of converting and to type , and force a string comparison by returning If the return from the reflected method is a null in either or , then the code sorts the null to the front of the list without doing ...
We have a list of names. We wort the names by surnames, in reverse order. By default, they would be sorted by first names, because they preced surnames. Function<String, String> fun = (String fullName) -> fullName.split("\s")[1]; We create aFunctionwhich is a key extractor. It ...

8 syntax we created a few eclipse snippets to save us from some typing. Our first example is to sort by employee number. In java 8 you can create a comparator in the form of a lambda expression. You might be asking how the compiler knows to convert the lambda expression to a ...
Return apositivevalue if this object islargerthan the other object. There are a few more specific rules to obey in the implementation, but the above is the primary requirements. Check out the JavaDoc for the details. Let's say you are sorting aListofStringelements. To sort them, each str...
