<h3>How to print a string in Java?</h3>
There are multiple ways to print a string in a Java, but one of them is using the system.out.println(string) command, which prints the string and gives a new line.
However, for this method, and any other, the string has to be set before it is printed, which does not happen for this problem. There should be a line setting the string like the example:
s = "ABC";

You cannot print a string without setting its value.
