How to Count the number of Words in a String in Java

by Abdul Rawoof A R Updated: Jan 24, 2023

To count the number of words and lines in a string in Java, you can use the following methods: 


  • To count the number of words in a string, you can use the "split" method of the String class to split the string into an array of words and then use the array's length property to get the number of words. The "length" property of the array will give you the number of words in the string. 
  • To count the number of lines in a string, you can use the "split" method of the String class to split the string into an array of lines and then use the array's length property to get the number of lines. The "length" property of the array will give you the number of lines in the string. 
  • Split: The split method of the String class in Java is used to split a string into an array of substrings based on a specified delimiter character or regular expression. 
  • Length: The length function is a property of the String class that returns the length of a string.  


Here is an example how to count the number of words and lines in a string in Java;
