create a method called xChar that will replace a specified char in a String with the 'X' character. The method must use a pointer to search and replace the char. The method should take as arguments the String to search through and a char variable that holds the char to be searched for and replaced.

The method should return a String that has been modified.

Note:

Strings in Java are immutable. This means they cannot be changed. For this question simply copy all characters to a new string replacing the character to search for with the 'X' character. 

Example Run:

Enter some text
Hello World

Enter a character to x
o

Here is your output
Hellx Wxrd
