Java's keywords have special meanings for Java compilers, which are used to represent a data type, or to represent the structure of a program. Reserved words are keywords reserved for Java, although they are not now keywords, but are likely to be keywords in later versions of the upgrade.List of Java keywords (sorted a
Use TreeMap to count the number of words and output words and bibliographies, with words sorted in ascending orderTreeMap is characterized by a non-repeating element, and the key value of the element can either be sorted by default comparable interface or sorted by comparator comparator, a comparator is designed for TreeMap, this comparator implements comparator

"152-reverse Words in a string (reverses the word in the string)""leetcode-Interview algorithm classic-java Implementation" "All topics Directory Index"Original QuestionGiven an input string, reverse the string word by word.For example,Given s = "the sky is blue" ,Return "blue is sky the" .Main TopicGiven a string, invert it, and its word does not goThinking of solving problemsReverses the entire string fir
Given an input string, reverse the string word by word.For example,Given s = " the sky is blue ",Return " blue is sky the ".Clarification:What constitutes a word? A sequence of non-space characters constitutes a word.Could the input string contain leading or trailing spaces? Yes. However, your reversed string should not contain leading or trailing spaces.How about multiple spaces between and words? Reduce them to a single space in the reverse

Given an input string, reverse the string word by word. A word is defined as a sequence of non-space characters.The input string does not contain leading or trailing spaces and the words is always separated by a single space.For example,Given s = " the sky is blue ",Return " blue is sky the ".Could do it in-place without allocating extra space?1, the beginning of the idea is to find the first and last word, and then exchange them two, but the problem
In this article, we will arrange the words in the array in reverse order, such as how old are you-> your are old
Sample Program Output results:
The A:How old are for you!? I Don ' t understandThe second:Understand don ' t I?! are old
Sample Code
public static void Main (string[] args) {char[] chars= the new String ("How old are you!?"
I Don ' t understand "). ToCharArray ();
System.out.println ("The" the "the");
