Question

当我输入“if conditional”时会发生这种情况。很抱歉带来了满满的代码，但是我整天都在尝试找出问题所在，但我仍在寻找问题。

import javax.swing.JOptionPane;

class Accounting2 {
    public static double VOS;
    public static double vatRate = 0.1;
    public static double expenseRate = 0.3;
    
    public static double person1, person2, person3;
    public static double[] dividend = new double[3];
    
    public static void printReport(double person1, double person2, double person3) {
        System.out.println("Value of supply : " + VOS);
        System.out.println("VAT : " + getVAT());
        System.out.println("Price : " + getPrice());
        System.out.println("Income : " + getIncome());
        System.out.println("Person1 : " + person1 +
                "\nPerson2 : " + person2 +
                "\nPerson3 : " + person3);
    }
        
    public static double getIncome() {
        return VOS - getExpense();
    }
    public static double getExpense() {
        return VOS * expenseRate;
    }
    public static double getPrice() {
        return VOS + getVAT();
    }
    public static double getVAT() {
        return VOS * vatRate;
    }
    
    public static double toPutGetIncome = getIncome(); // error hapeens here (Syntax error on token ";", { expected after this token)
    
    // The "if conditional" starts from here
    if( toPutGetIncome >= 10000 ) {
        for (int n = 0; n < 3; n++) {
            dividend[n] = Double.parseDouble(JOptionPane.showInputDialog("Enter a Dividend of Person" + (n+1)));
            if(dividend[0] + dividend[1] + dividend[2] > 1) { System.out.println("Dividend over"); return; }
        }
        if(dividend[0] + dividend[1] + dividend[2] < 1) { System.out.println("Dividend short"); return; }
    }
    
    
    if( toPutGetIncome < 10000 ) { person1 = getIncome(); person2 = 0; person3 = 0; }
    else{ person1 = getIncome()*dividend[0]; person2 = getIncome()*dividend[1]; person3 = getIncome()*dividend[2]; }
    // ends
        
}

public class AccountingApp2 {

    public static void main(String[] args) {
        
        Accounting2.VOS = Double.parseDouble(JOptionPane.showInputDialog("Enter a VOS"));
        if( Accounting2.VOS <= 0 ) { System.out.println("Wrong VOS"); return; }
        
        Accounting2.printReport(Accounting2.person1, Accounting2.person2, Accounting2.person3);
        
    }

} // the other error happens here (Syntax error, insert "}" to complete ClassBody)

我不确定它是否对你有帮助我正在研究外部 class 和内部 class。所有代码都在 public class AccountngApp2 中。我制作了另一个 class Accounting2 以从 AccountingApp2 移动方法，但在我移动方法时发生错误。

    // The "if conditional" starts from here
    if( toPutGetIncome >= 10000 ) {
        for (int n = 0; n < 3; n++) {
            dividend[n] = Double.parseDouble(JOptionPane.showInputDialog("Enter a Dividend of Person" + (n+1)));
            if(dividend[0] + dividend[1] + dividend[2] > 1) { System.out.println("Dividend over"); return; }
        }
        if(dividend[0] + dividend[1] + dividend[2] < 1) { System.out.println("Dividend short"); return; }
    }
    
    
    if( toPutGetIncome < 10000 ) { person1 = getIncome(); person2 = 0; person3 = 0; }
    else{ person1 = getIncome()*dividend[0]; person2 = getIncome()*dividend[1]; person3 = getIncome()*dividend[2]; }
    // ends

这是无效的。 if 语句必须在方法、构造函数或静态初始值设定项中。
