Split String by Pipe Character ( | ) in Java

In this example, we will see how to write a java program to split a string by pipe | symbol.

Java Program to split string by Pipe

Pipe represented by | symbol, is a meta character in regex. If you simply pass the | in split method like this: str.split("|") then it would return an unexpected output. Instead of splitting the string by |, it would create substring for each character in the input string.

To correctly split the string by |, you need to escape this character and pass this regex in the split method: split("\\|")

Complete Java code:

public class JavaExample{
  public static void main(String args[]){
    //a string that contains pipe characters
    String str = "Apple|Orange|Banana|Mango";

    //split string by pipe
    String[] strArray = str.split("\\|");

    //print substrings
    System.out.println("Substring after splitting by pipe: ");
    for(String s:strArray){
      System.out.println(s);
    }
  }
}
