私は、従業員のタイプと作業時間（オーバータイムと非オーバータイム）に基づいて税金を計算する小さなプログラムを作成しています。私は自分のコードの完全なコピーを含めます。オーバーロードされた関数に渡す -

私の最初の関数は、正規従業員のための私のgrossPayCalcに渡す部分がエラーを持っているようだし、いくつかの基本的な情報（empPayRateとempHours）を尋ね、あなたにそれが（請負業者または定期的）である従業員のどのようなタイプの入力を持っています。これは、grossPayCalcに渡すコードです。
if (empType == 1)
{
System.out.printf("Input employee's pay rate:%n");
empPayRate = input.nextDouble();
System.out.printf("Input employee's hours worked:%n");
empHours = input.nextDouble();
grossPayCalc(empPayRate, empHours);
}
これは、私はエラーを取得した後
public double grossPayCalc(double empPayRate, double empHours)
//calculate regular employee pay
{
if (empHours <= 40)
{
empGrossPay = empPayRate * empHours;
taxCalc(empHours, empPayRate, empGrossPay);
}
else
{
otPayCalc(empHours, empPayRate, empGrossPay);
}
return empPayRate;
}
に渡す必要があります。
What type of employee is this?
Enter 1 for regular employee and 2 for contractors, or 3 to quit: 1
Input employee's pay rate:
50
Input employee's hours worked:
40

このエラーの原因は不明です。これは、メソッド/メソッドのオーバーロードを渡す際にエラーですか？私はこのエラーの原因を知りたいと思っています。また、これが今後起こることをどうやって防ぐことができますか？
