Final answer:
The given Java code snippet does not show an obvious compiler error. Ensure the class 'Q1' is in a file named 'Q1.java' and that there is no name conflict. Without the full code or specific error message, accurate troubleshooting is limited.
Step-by-step explanation:
The code provided appears to be a Java program that defines a class Q1 with a method getInstance() that returns a new instance of the Q1 class. However, you mentioned there is a compiler error, but based on the code snippet provided, there isn't an obvious syntax error or type mismatch that would cause a compilation failure. It is important to ensure that the class is saved in a file named Q1.java and that there are no other classes defined in the same file with the name Q1, as that would cause a conflict. If there are additional parts of the code not shown that might be causing the error, please provide the full context or specific error message to enable more accurate troubleshooting.
