In this blog post, I will be explaining how you can split a String via Java. Consider the following code snippet:

package learnjava.strings;

public class SplitStringDemo {

    public static void main(String[] args) { 
        String str = "This is a test String"; 
        String[] words = str.split(" "); 
        System.out.println("There are "+words.length+" words"); 
        for(String word:words) { 
            System.out.println(word); 
        }
    }
}

There is a method called String.split. It accepts any regular expression. It splits the String around matches of the specified regular expression. Here, I am simply using a space. This will split the input sentence into words. So if you run the above code, you will get the following output:

There are 5 words
This
is
a
test
String
