How to Split a String in Java with Delimiter?

Last Updated : 23 Jul, 2025

In Java, the split() method of the String class is used to split a string into an array of substrings based on a specified delimiter. The best example of this is CSV (Comma Separated Values) files.

Program to Split a String with Delimiter in Java

Here is a simple program to split a string with a comma delimiter in Java using the split() method:

Java 
// Java program to split a string with a Comma delimiter

public class SplitString {
    public static void main(String[] args) {
      
        // Declare a string with comma delimiter
        String s = "Hello,Good,Morning";
        
        // Split the string using comma as the delimiter
        String[] b = s.split(",");
        
        // Print each fruit on a new line
        for (String a : b) {
            System.out.println(a);
        }
    }
}

Output
Hello
Good
Morning

Other Ways to Split a String with Delimiter in Java

Apart from the simple method demonstrated above, there are few more methods which we can use to split the string in Java.

Using String Tokenizer class

The String Tokenizer class in Java is present in java.util package. The main purpose of String Tokenizer is to divide or break the given strings into several tokens based upon the delimiter.

Example:

Java 
// Java program to split a string with delimeter using String Tokenizer Class
import java.util.StringTokenizer;

public class StringTokenizerExample {
  
    public static void main(String[] args) {
      
     // Creating a new string tokenizer object  with given input string
     StringTokenizer st  = new StringTokenizer("Java Programming");
            
     System.out.println("No. of tokens:" +st.countTokens());
                         
     // Iterate through token and print each token
     while (st.hasMoreTokens())
        {
           // Get next token and print it with space
           System.out.println("" +st.nextToken());
        }
    }
}

Output
No. of tokens:2
Java
Programming


Using Scanner Class

The Scanner class in Java allow a user to read input from the keyboard. Scanner class is used to tokenize an input string. Java Scanner class is present in java.util package.

Example:

Java 
// Java program to split a string with delimeter using String Scanner Class
import java.util.Scanner;

public class Test {
  
    public static void main(String[] args) {
      
      String s = "Geeks For Geeks";
      
      // Create a Scanner object with input string
      Scanner sc = new Scanner(s);
      
      System.out.println("");
      
      // Iterate through token and print each token
      while(sc.hasNext())
      {
        System.out.println(sc.next());
      }
    }
}

Output
Geeks
For
Geeks
