trouble deleting spaces from String

Question

I am working with appium automation on a native android app

I have a MobileElement that I want to get the text from

MobileElement likesElement = (MobileElement) driver.findElement(By.id("com.instagram.android:id/row_feed_textview_likes"));

And then I have the String

String likesVal = likesElement.getText();

When I run System.out.println(likesVal); it prints:

Liked by you and 107 others

I need to delete everything but 107 so I can run parseInt on likesVal

I have tried

likesVal= likesVal.replaceAll("[*a-zA-Z_.-]", "");
likesVal= likesVal.replaceAll(" ", "");
StringUtils.deleteWhitespace(likesVal);
int likes = Integer.parseInt(likesVal);
System.out.println(likes);

But I am getting a java.lang.NumberFormatException For input string: "107 " on int likes = Integer.parseInt(likesVal);

After stripping likesVal of everything but numbers, why wasnt the space that comes before "others" in likesVal deleted?

After stripping likesVal of everything but numbers I need "107" to be printed instead of "107 "

Answer 1

I suggest using a pattern to replace all non-digits (\\D). Like,

String tmp = "Liked by you and 107 others";
// String likesVal = likesElement.getText().replaceAll("\\D+", "");
String likesVal = tmp.replaceAll("\\D+", "");
int likes = Integer.parseInt(likesVal);
System.out.println(likes);

Outputs

107

as requested.
