How to do it without char c = scanner.next().charAt(0) as I didn't learn how to use 'At' and read function invokes only one character while I want it to read the entire line.

1Define "invoke a character". Make your question clear. If you want to read an entire line from a Scanner, then call nextLine(). The javadoc is your friend. – JB Nizet Apr 01 '17 at 15:50

If you want to read a **line** why don't you use `nextLine()` then? – QBrute Apr 01 '17 at 15:56

guys nextLine() is for a string and invoke a character means that the user has to give the character – Ruchir Apr 02 '17 at 12:09

By "invoke" do you mean "Get a character from user input"? – slim Apr 02 '17 at 18:18

One of the approaches can be: read the line using nextLine() and store it in a String and then use charAt() something like:
String line = reader.nextLine();
char c = line.charAt(0);
