The given character, unless it is a regular expression meta You can also use the Elvis operator to return from a function early, as shown in the following example: This is usually written ? Otherwise if the expression on the left is null, then use the expression to the right of the elvis operator (which is 0 in this case). A similar operator is the null coalescing operator, where the boolean truth check is replaced with a check for non-null instead. You can use takeIf {} with an elvis operator: val x = result1.takeIf { condition } ? It accesses the built-in media player services such as playing audio, video, etc. After learning Java regex tutorial, you will be able to test your regular expressions by the Java Regex Tester Tool..
