Removes a specific character from a string in Java

For example, when we specify the character to be deleted as aeiou, we give a string of "vowel war": Hawaii vs. groney, which should convert the string to vwls: HW vs grzny

This problem is found in the book Programming interviews exposed This has been explained in C, but I am interested in Java

Solution

A simple method is to use regular expressions:

"Battle of the Vowels:Hawaii vs Gronzy".replaceAll("[aeIoU]","")
