Answer:
Software for personal computers is typically developed and distributed independently from the hardware or operating system manufacturers. Many personal computer users no longer need to write their own programs to make any use of a personal computer, although end-user programming is still feasible. This contrasts with mobile systems, where software is often only available through a manufacturer-supported channel. And end-user program development may be discouraged by lack of support by the manufacturer.

<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";
Hence the correct option regarding the error is given as follows:
You cannot print a string without setting its value.
