Replacing All Instances of a Character in a String in Java

To eliminate all instances of a specific character from a String in Java, we can employ the replace() method. This method offers two variations: one that takes a single character as an argument and another that accepts a sequence of characters (such as a String).

The example provided employs the form that replaces a character with a different character. However, when the aim is to remove a character completely, we should utilize the variation that replaces the character with an empty String.

To achieve this, we modify the code as follows:

str = str.replace("X", "");

This modification ensures that the character "X" is replaced by an empty String, effectively removing it from the String.
