In Java How to Get all Text After Special Character from String?

Java substring() utility is a very powerful library if you want to perform multiple special operations on String.

It simply returns a substring of the specific string based on number of operations like indexOf() or lastIndexOf().

In this tutorial we will go ver very simple example of grabbing everything after special character _ and *.

Just open your Eclipse IDE, copy below code and try running as Java Application.

CrunchifyGetStringAfterChar.java

package crunchify.com.java.tutorials;

/**
 * @author Crunchify.com
 * Program: Get everything after Special character like _ or : or * from String in java
 *
 */

public class CrunchifyGetStringAfterChar {

    public static void main(String[] args) {

        String crunchifyStr = "Hey.. This is Crunchify.com";
        String crunchifyStr2 = "HELLO_THIS_IS_CRUNCHIFY_COM";
        String crunchifyStr3 = "This is simple substring example *";

        // substring(): Returns a string that is a substring of this string.
        // The substring begins with the character at the specified index and extends to the end of this string.
        crunchifyLog(crunchifyStr.substring(crunchifyStr.indexOf(".") + 2));

        // indexOf(): Returns the index within this string of the first occurrence of the specified substring.
        crunchifyLog(crunchifyStr2.substring(crunchifyStr2.indexOf("_") + 1));

        // lastIndexOf(): Returns the index within this string of the last occurrence of the specified substring.
        // The last occurrence of the empty string "" is considered to occur at the index value this.length().
        crunchifyLog(crunchifyStr3.lastIndexOf("*") + "");

        crunchifyLog(crunchifyStr2.indexOf("_") + "");
    }

    private static void crunchifyLog(String string) {
        System.out.println(string);

    }
}

IntelliJ IDEA Console output:

Just run above program as a Java program and you will see result as below.

This is Crunchify.com
THIS_IS_CRUNCHIFY_COM

Let me know if you prefer to perform the same action using Apache Commons library.

I personally think, it’s not required to add extra dependency just for this.
