Hi, i am facing a problem on my java assignment recently which require me to read customer records from a text file and pass it into array. After that i need to change the first letter of the name to uppercase and sort it according to the name. However i could only get the data from the text file and not pass it into arraylist. Can anyone help pls? If possible can provide some example? thank in advance=D Below is an attachment of my code and the text file as well as my output.
