NBEANS找不到或加载Main类

Question

您好，好日子，这是第一个面向对象的类，我抛出了这个错误？我该如何修复？谢谢。 错误 ------------------------------------------------------------------------------- ------------------

--- exec-maven-plugin:3.0.0:exec (default-cli) @ Suma2 --- 错误：找不到或加载主类Com.mycompany.suma2.suma.sumamain 引起的： 命令执行失败。

有两个代码，这是

package com.mycompany.suma2.suma;
 
 
public class SumaMain {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
         
         
        System.out.println("Give me the first value ");
        int valueOne=sc.nextInt();
 
  System.out.println("Give me the first value");
        int valueTwo = sc.nextInt() ;
         
         
        Sum values = new Sum(valueOne, valueTwo){
        values.Print();
    }                    
} 

另一个代码

 
 
  
public class Sum {
        private int vOne, vTwo, Result ;
     
    public Sum (int valueOne , int valueTwo ) {
           this.vOne = valueOne ;
        this.VTwo = valueTwo ;
        }   
    public void Operation(){
    Result = vOne +vTwo ;
     
    }
    public void Print(){
        Operation();
        System.out.println("The result of the sum is : + Result ");
     
    }
}
