Here you will learn how to split string in java.
We can split string in Java using split() method of java.lang.String class. It takes a regular expression as an argument and returns an array of strings.
Syntax:
|
1 |
public String[] split(String regex) |
Split String in Java Example
Below program will split the string by space.
|
1 2 3 4 5 6 7 8 9 10 |
public class SplitStringJava { public static void main(String...s){ String str = "I Love Java Programming"; String strArray[] = str.split("\\s"); //split by space for(int i=0;i<strArray.length;++i){ System.out.println(strArray[i]); } } } |
Output
I
Love
Java
Programming
There are few special characters like ., ?, |, +, etc. and some escape characters like \n, \t, \b, etc. that must be escaped before using as a regular expression in split() method. We can escape them by using two backslash characters i.e. \\.
For example if you want to split the string by + character then you have to use \\+ as a regular expression in split() method.
Java String Split with Length
You can split a string by regular expression along with length using another variant of split() method.
Syntax:
|
1 |
public String[] split(String regex, int length) |
Example
|
1 2 3 4 5 6 7 8 9 10 |
public class SplitStringJava { public static void main(String...s){ String str = "I Love Java Programming"; String strArray[] = str.split("\\s", 2); for(int i=0;i<strArray.length;++i){ System.out.println(strArray[i]); } } } |
Output
I
Love Java Programming
As you can see in above example that the string is split into 2 parts because we have used length as 2.
