Homework Equations

The Attempt at a Solution

So essentially, the code is supposed to return a percent of how many people were accepted. But regardless of how many failed or passed, it always returns as 0.0!

My brain is a little tired so you'll have to excuse me for lack of efficiency. But I still believe I should understand why this is happening. Here is the results after compiling:

My method returnPercentage is meant to give the percent.

public String returnPercentage() {
        int allScores = this.examScores.size();
        double acceptanceRate = 100*(this.accepted/allScores);  <<--- here
        this.acceptedPercent = acceptanceRate;
        System.out.println();
        return "Acceptance percentage: " + this.acceptedPercent;

What kind of division is going on in this expression? -- this.accepted/allScores

Well that is embarrassing!

You're not the first to make that mistake, by a long shot.
