Java String split() Example

class Main {
 public static void main(String[] args) {
   String text = "Java is a fun programming language";
   // split string from space
   String[] result = text.split(" ");

   System.out.print("result = ");
   for (String str : result) {
     System.out.print(str + ", ");
   }
 }
}
// Output: result = Java, is, a, fun, programming, language,
 
Example 1: split() Without limit Parameter
 
// importing Arrays to convert array to string
// used for printing arrays
import java.util.Arrays;
class Main {
 public static void main(String[] args) {
   String vowels = "a::b::c::d:e";
   // splitting the string at "::"
   // storing the result in an array of strings
   String[] result = vowels.split("::");

   // converting array to string and printing it
   System.out.println("result = " + Arrays.toString(result));
 }
}
 
Example 2: split() With limit Parameter
// importing Arrays to convert array to string
import java.util.Arrays;
class Main {
 public static void main(String[] args) {
   String vowels = "a:bc:de:fg:h";
   // splitting array at ":"
   // limit is -2; array contains all substrings
   String[] result = vowels.split(":", -2);
   System.out.println("result when limit is -2 = " + Arrays.toString(result));
   // limit is 0; array contains all substrings
   result = vowels.split(":", 0);
   System.out.println("result when limit is 0 = " + Arrays.toString(result));
   // limit is 2; array contains a maximum of 2 substrings
   result = vowels.split(":", 2);
   System.out.println("result when limit is 2 = " + Arrays.toString(result));
   // limit is 4; array contains a maximum of 4 substrings
   result = vowels.split(":", 4);
   System.out.println("result when limit is 4 = " + Arrays.toString(result));
   // limit is 10; array contains a maximum of 10 substrings
   result = vowels.split(":", 10);
   System.out.println("result when limit is 10 = " + Arrays.toString(result));
 }
}
 
result when limit is -2 = [a, bc, de, fg, h]
result when limit is 0 = [a, bc, de, fg, h]
result when limit is 2 = [a, bc:de:fg:h]
result when limit is 4 = [a, bc, de, fg:h]
result when limit is 10 = [a, bc, de, fg, h]
