[Solved] call method with parameters java [closed]

There’s a couple factors missing from your question that makes me unable to completely answer them, but:

Is the courseGrade method in a separate class or in the same class as your public static void main method?

Yes: Create a new instance of the separate class by doing: public SeparateClass instance = new SeparateClass(); inside of public static void main

After that, call this from your main method: double grade = instance.courseGrade(homeworkWeightedScore, examTwoWeightedScore, examTwoWeightedScore);

No: Make the courseGrade method static, you can’t call a non-static method from a static method (replace public double courseGrade with public static double courseGrade). After that, inside of your main method, do this: double d = courseGrade(homeworkWeightedScore, examTwoWeightedScore, examTwoWeightedScore);

I hope this helps.
