Java Program to Print even length words

In this article, we will understand how to print even length words. String is a datatype that contains one or more characters and is enclosed in double quotes (“ ”). Char is a datatype that contains an alphabets or an integer or an special character.

Below is a demonstration of the same −

Suppose our input is −

Input string: Java Programming are cool

The desired output would be −

The words with even lengths are:
Java
cool

Algorithm

Step 1 - START
Step 2 - Declare a string namely input_string.
Step 3 - Define the values.
Step 4 - Iterate over the string usinf a for-loop, compute word.length() modulus of 2 for each word to check if the length gets completely divided by 2. Store the words.
Step 5 - Display the result
Step 6 - Stop

Example 1

Here, we bind all the operations together under the ‘main’ function.

public class EvenLengths {
   public static void main(String[] args) {
      String input_string = "Java Programming are cool";
      System.out.println("The string is defined as: " +input_string);
      System.out.println("\nThe words with even lengths are: ");
      for (String word : input_string.split(" "))
         if (word.length() % 2 == 0)
            System.out.println(word);
   }
}

Output

The string is defined as: Java Programming are cool

The words with even lengths are:
Java
cool

Example 2

Here, we encapsulate the operations into functions exhibiting object-oriented programming.

public class EvenLengths {
   public static void printWords(String input_string) {
      System.out.println("\nThe words with even lengths are: ");
      for (String word : input_string.split(" "))
         if (word.length() % 2 == 0)
            System.out.println(word);
   }
   public static void main(String[] args) {
      String input_string = "Java Programming are cool";
      System.out.println("The string is defined as: " +input_string);
      printWords(input_string);
   }
}

Output

The string is defined as: Java Programming are cool

The words with even lengths are:
Java
cool
