在字符串中打印偶数长度单词的 Java 程序

原文:https://www . geesforgeks . org/Java-程序到打印-偶数长度字符串中的单词/

给定一个字符串 str ，编写一个 Java 程序，打印给定字符串中所有长度为偶数的单词。

例:

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

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

进场:

  • Take strings

  • With the help of [split () method in string class, the string is broken into words. It is a rope used to break sentences. So here ""(space) is passed as a parameter. As a result, the words of the string are split into string arrays

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

    ```](https://www.geeksforgeeks.org/split-string-java-examples/) * Returns, with the help of foreach loop in Java, traversing every word in the returned string array.

    ```java for(String word : words) { }

    ```

  • Use the string.length () function to calculate the length of each word.

    ```java int lengthOfWord = word.length();

    ```

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

下面是上述方法的实现:

// 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);
    }
}

输出:

am
Geek
