What is the best way to print a string so that each word appears on a new line in Java, and how can I modify the output accordingly?

I have a string like "I am a boy" and I want to print it so that each word appears on a separate line, like:

I  
am  
a  
boy

What’s the right approach to achieve this using a new line in Java for each word?

This is the most straightforward and readable approach:

String sentence = "I am a boy";
String[] words = sentence.split(" ");

for (String word : words) {
    System.out.println(word);
}

You’re breaking the sentence into parts using .split(" "), then printing each word with System.out.println(), which naturally adds a new line after each word.

If you prefer a quick one-liner and don’t mind formatting the string directly:

String sentence = "I am a boy";
System.out.println(sentence.replace(" ", "\n"));

You’re telling Java to replace every space with a newline \n. The entire string prints in one go, with each word on a new line.
