Write a Java program to count the characters in each word in a given sentence?
Examples:
Input : geeks for geeks Output : geeks->5 for->3 geeks->5
Approach:Here we have to find out number of words in a sentence and the corresponding character count of each word.
- Here first we create an equivalent char array of given String.
- Now we iterate the char array using for loop. Inside for loop we declare a String with empty implementation.
- Whenever we found an alphabet we will perform concatination of that alphabet with the String variable and increment the value of i.
- Now when i reaches to a space it will come out from the while loop and now String variable has the word which is previous of space.
- Now we will print the String variable with the length of the String.
class CountCharacterInEachWords { static void count(String str) { // Create an char array of given String char[] ch = str.toCharArray(); for (int i = 0; i < ch.length; i++) { // Declare an String with empty initialization String s = ""; // When the character is not space while (i < ch.length && ch[i] != ' ') { // concat with the declared String s = s + ch[i]; i++; } if (s.length() > 0) System.out.println(s + "->" + s.length()); } } public static void main(String[] args) { String str = "geeks for geeks"; count(str); } } |
