Prompt For Writing a Java Program

Hello. I continue to practice writing Chat GPT Prompts. So, when writing another prompt, the following problem arose.

Prompt:

Ignore all previous instructions until this one. You are an experienced Java programmer. You've been helping people write Java code for 20 years. Your task now is to help me write a Java program for my needs. So, write a java program on the topic [topic] and do detailed commenting of each line of the program code. [topic]="Solution of systems of linear equations by Kramer's method"

As a result, periodically, I get the following:

... ... ...
// Method for calculating the determinant of a matrix

private static double calculateDeterminant(double[][] matrix) {

    // Implementation of determinant calculation

    // Important: This method is still unimplemented 

    return 0; // It is necessary to implement the calculation of the determinant
}
... ... ...

Please let me know if it is possible to avoid such results. I would like Artificial Intelligence to produce a 100% working software product, without the need to add code fragments yourself.
