    Default Issues with changing values in for loops

    Edit: solved

    I am trying to use a for loop with the for(type *:*) syntax. I started in C++ so have never used this syntax. I am attempting to change some values inside this array but the values do not seem to be staying after exiting the loop.

    for(char eachChar : msgArr)
    {
    	System.out.println(eachChar);
    	eachChar = (char) (eachChar + 1);
    	System.out.println(eachChar);
    }
    System.out.println(msgArr);

    If message array starts as "test" the output will be:
    t
    u
    e
    f
    s
    t
    t
    u
    test

    The expected output should be uftu at the last line, but instead continues to say test! Am I missing something silly or am I misunderstanding this for loop syntax.

    I appreciate any assistance!

    --- Update ---

    Ok eachChar is local variable to the for loop! I used a vanilla loop and that worked.
