エラーは、TestPayroll の次のステートメントで「適切なコンストラクタが見つかりません」ということです: Payroll payroll = new Payroll(name,weeksPay); コンストラクターは何であるべきか、それは Payroll クラスにあるべきだと思います。

Tiny Tim、Brad Pitt、Madonna の 1 週間の給料を表示したいと思います。ありがとうございました！

public class TestPayroll {

    private String [] name = {"Tiny Tim", "Brad Pitt", "Madonna"};

    private double weeksPay;

    //Payroll object
    Payroll payroll = new Payroll(name, weeksPay);


    public static void main(String[] args) {

    //Display weekly pay
    JOptionPane.showMessageDialog(null, "%s's pay for the week is: $%.2f\n", payroll[0].getName(), payroll[0].getWeeksPay()); 

    }

次のコンストラクタがありますPayroll

    public Payroll(String name, double weeksPay) {/* some code */}

と

    public Payroll() {/* some */}

String[]そして、あなたは最初の引数として渡しています
