Pattern split(CharSequence) method in Java with Examples

Last Updated : 21 Feb, 2019

split(CharSequence) method of a Pattern class used to splits the given char sequence passed as parameter to method around matches of this pattern.This method can split charSequence into an array of String's, using the regular expression used to compile the pattern as a delimiter.so we can say that the method returns the array of strings computed by splitting the input around matches of this pattern. Syntax:

public String[] split(CharSequence input)

Parameters: This method accepts a single parameter input which represents character sequence to be split. Return value: This method returns the array of strings computed by splitting the input around matches of this pattern. Below programs illustrate the split(CharSequence) method: Program 1:

Java

// Java program to demonstrate
// Pattern.split(CharSequence) method

import java.util.regex.*;

public class GFG {
    public static void main(String[] args)
    {
        // create a REGEX String
        String REGEX = "ee";

        // create the string
        // in which you want to search
        String actualString
            = "geeksforgeeks";

        // create a Pattern using REGEX
        Pattern pattern = Pattern.compile(REGEX);

        // split the text
        String[] array = pattern.split(actualString);

        // print array
        for (int i = 0; i < array.length; i++) {
            System.out.println("array[" + i
                               + "]=" + array[i]);
        }
    }
}

Output:

array[0]=g
array[1]=ksforg
array[2]=ks

Program 2:

Java

// Java program to demonstrate
// Pattern.split(CharSequence) method

import java.util.regex.*;

public class GFG {
    public static void main(String[] args)
    {
        // create a REGEX String
        String REGEX = "ke";

        // create the string
        // in which you want to search
        String actualString
            = "Bharat ke Veer Portal";

        // create a Pattern using REGEX
        Pattern pattern = Pattern.compile(REGEX);

        // split the text
        String[] array = pattern.split(actualString);

        // print array
        for (int i = 0; i < array.length; i++) {
            System.out.println("array[" + i
                               + "]=" + array[i]);
        }
    }
}
