Question

class WageCalculator_1 {

    public static void main(String[] args) {
       WagecalculatorApp WageCalculatorObject = new WagecalculatorApp(); 
    }

    private double baseRate;
    private double overtimeMultiplier;
    private int hours;
    private int overtime;
    private int overtimeHours;
    private int wages;
    private String multi;

    Scanner keyboard = new Scanner(System.in);

    public WageCalculator_1(double baseRate, int hours) 
    {
       this(baseRate, 1.5, hours);
    }

    public WageCalculator_1(double baseRate, double overtimeMultiplier, int hours) {
       System.out.print("Enter your base rate: ");
       baseRate = keyboard.nextDouble();

       WageCalculatorObject.wagecalc(baseRate);
       System.out.print("Enter your hours: ");
       hours = keyboard.nextInt();

       WageCalculatorObject.wagecalc(hours);
       System.out.print("Would you like to enter an overtime multiplier (yes/no)? ");
       multi = keyboard.next();

       if (hours > 40) {  
           System.out.print("what is the overtime multiplier? ");
           overtimeMultiplier = keyboard.nextInt();
       } else if (hours <= 40) { 
           wages = (int) (hours * baseRate);
           overtimeMultiplier = 0;    
       } else {   
           wages = (int) (40 * baseRate);       
           overtimeHours = hours - 40;
           overtime = (int) (overtimeHours * ( 1.5 * baseRate));   
           wages += overtime;              
       }   
    }
}

我遇到过WageCalculatorObject的问题。我试图使用它时不断给我这个错误。我一直在努力解决这个问题，不知道该怎么办。它给了我no error message。

您没有WageCalculatorApp对象。具体来说，除非你提供更多代码，否则在初始化WageCalculatorObject对象时，你永远不会调用它，因此你调用的任何方法都不会返回任何内容（除非你没有显示WageCalculatorApp的代码）。除非您创建一个WageCalculatorApp对象，否则不能从它返回任何内容，因为它不存在。

如何修复“类中的方法不能应用于给定类型”错误？
