How to get the last word from a text?

Question

Well I have to count the times that one word appear in a text. Each word is between one space.
But my code doesnt count the last word. I dont know how to do it.
Language : java.
Any advice?
I thought to get the last space and take that position + 1 to the length but It doesnt worked :(

Answer 1

String str = "one two three four five six seven eight nine";
// If you know the last word
int idx = str.indexOf("nine");
System.out.println(str.substring(idx));

// If you know or not the last word
String[] words = str.split("\\s+");
System.out.println(words[words.length - 1]);

You should use the array variant, like that:

String str = "w1 w4 w2 w1 w5 w3 w1";
String matchWord = "w1";

String[] words = str.split("\\s+");

int count = 0;

// Iterating to the last element
// Or use 'for each' loop for simplicity
for (int i = 0; i < words.length; i++) {
if (words[i].equals(matchWord)) {
count++;
}
}
System.out.printf("The word %s is found %d times.\n", matchWord, count);

split the text into an array and then get the final index.. use the length and then -1 because arrays start at 0

I literally have no idea. I was about to post it in css...then i saw "Language: java" in your text and i was all like,"Well @#$*". No worries, you should use a scanner then use .length at the end of the array. That is all I know. Sorry...hope this helped.
