RuntimeException：不可編譯的源代碼（Netbeans）

Question

這是我不斷收到並且不確定如何更正它的錯誤。

異常在線程 「主」 了java.lang.RuntimeException：不可編譯 源代碼 - 在 salescommission.SalesCommission.main（SalesCommission.java:27）表達的非法起動

package salescommission; 

/**

public class SalesCommission { 

    /** 
    * @param args the command line arguments 
    */ 
    public static void main(String[] args){ 
     // public class SalesCommission { 
    // fixed salary variable 
    double fixedSalary; 
    // variable of the value of sale person's annual sales 
    double annualSales; 
    //the commission earned 
    double commission; 


    private final double annualSales; 
    private double commission; 
    private double fixedSalary; 
    public SalesCommission(double annualSales){ 
     this.annualSales=annualSales; 
     double commission = 0.25*annualSales; //The current commission 25% of total sales. 
     int fixedSalary = 75000; // set fixed salary is 75000$ 
    } 
    public double getTotalAnnualCompensation(){// calculate The total annual compensation is the fixed salary plus the commission earned 
     return fixedSalary+commission; 
    } 
} 

Answer 1

把類變量和方法定義放在main方法之外，那麼它應該工作。

Answer 2

你只需在雙重佣金後忘記「}」 :-)

package salescommission; 

/**

* @author Michael 
*/ 
public class SalesCommission { 

    /** 
    * @param args the command line arguments 
    */ 
    public static void main(String[] args) { 
     // public class SalesCommission { 
     // fixed salary variable 
     double fixedSalary; 
     // variable of the value of sale person's annual sales 
     double annualSales; 
     //the commission earned 
     double commission; 
    } 
    private final double annualSales; 
    private double commission; 
    private double fixedSalary; 

    public SalesCommission(double annualSales) { 
     this.annualSales = annualSales; 
     double commission = 0.25 * annualSales; //The current commission 25% of total sales. 
     int fixedSalary = 75000; // set fixed salary is 75000$ 
    } 

    public double getTotalAnnualCompensation() {// calculate The total annual compensation is the fixed salary plus the commission earned 
     return fixedSalary + commission; 
    } 
} 

但隨後的代碼沒有任何意義，你必須運行在主方法的方法：O）

Answer 3

這不是一個Netbeans的錯誤...你的主要方法沒有一個閉合大括號:)

public static void main(String[] args) { 
    // public class SalesCommission { 
    // fixed salary variable 
    double fixedSalary; 
    // variable of the value of sale person's annual sales 
    double annualSales; 
    //the commission earned 
    double commission; 
}
