Java program to print Even length words in a String

Given a string str, write a Java program to print all words with even length in the given string. Examples:

Input: s = "This is a java language"
Output: This
        is
        java
        language 

Input: s = "i am GFG"
Output: am

Approach:

• Take the string
• Break the string into words with the help of split() method in String class. It takes the string by which the sentence is to be broken. So here ” “(space) is passed as the parameter. As a result, the words of the string are split and returned as a string array

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

• Traverse each word in the string array returned with the help of Foreach loop in Java.

for(String word : words)
{ }

• Calculate the length of each word using String.length() function.

int lengthOfWord = word.length();

• If the length is even, then print the word.

Below is the implementation of the above approach: 

Java

// Java program to print
// even length words in a string

class GfG {
 public static void printWords(String s)
 {

  // Splits Str into all possible tokens
  for (String word : s.split(" "))

   // if length is even
   if (word.length() % 2 == 0)

    // Print the word
    System.out.println(word);
 }

 // Driver Code
 public static void main(String[] args)
 {

  String s = "i am Geeks for Geeks and a Geek";
  printWords(s);
 }
}

Output:

am
Geek

Time complexity: O(n) where n is length of given string
Auxiliary Space: O(1)
