Never mind. I figured it out. There is a method called replace that is
associated with the string class. Here is how to use it.
String word1 = "cot";
System.out.println(word1);
word1 = word1.replace("o", "a");
System.out.println(word1);
Anyone who has trouble with this issue, just put together this little program
and see what happens. Best of all, I didn't get this from a textbook. I figured
it all on my own by looking up the verrious methods for class string and
experimenting. Now all I need to do is learn how to replace characters in
specific positions within a string verriable.

Subject: Java Replacing characters
How do I replace a character in a string varriable with another.
string word1;
word1 = "cot"
How would I for example replace the o with an a. I know that the method
charAt() can be used to extract a character from a group of characters within a
string. I know that subString method can be used to extract a parcial string
from a string varriable. I also know that indexOf method can be used to find a
character or group of characters within a string varriable. I am not sure how
to insert, or even replace a character or group of characters within a string
varriable. Can someone help me with this issue? Thanks.
