类型表达式必须是阵列类型的错误JAVA

Question

package p1; 
public class Matrix{ 


    public Matrix(int b,Vector...vectors) { 

    double myArray[][] = new double[vectors.length][]; 
    int row = vectors.length; 

    int column = vectors.length; 
    for (int i = 0; i < row; i++) { 
     myArray[i] = new double[column]; 
    } 


    for (int i = 0; i < row; i++) { 
     for (int j = 0; j < column; j++) { 

      if(b==0) 
      { 

       myArray[i][j] = vectors[i][j]; // ERROR HERE 
      } 
      else 
      { 
       myArray[j][i] = vectors[i][j]; // ERROR HERE 
     } 
    } 
} 
} 

} 

错误：类型的表达式必须是阵列类型的错误，但它解析成矢量

我不能两种载体整合到一个2D阵列

的在Vector类的定义如下：

public class Vector { 

    public double[] getYourArray() { 
     return yourArray; 
    } 

    public void setYourArray(double[] yourArray) { 
     this.yourArray = yourArray; 
    } 

    public double yourArray[]; 

    public Vector(double...yourArray) { 
     this.yourArray = yourArray;                                                     
    } 
}

根据您所提供的的Vector类的定义，下面应该解决您的合作de：

package p1; 
public class Matrix { 

    public Matrix(int b,Vector...vectors) { 

     double myArray[][] = new double[vectors.length][]; 
     int row = vectors.length; 

     int column = vectors.length; 
     for (int i = 0; i < row; i++) { 
      myArray[i] = new double[column]; 
     } 


     for (int i = 0; i < row; i++) { 
      for (int j = 0; j < column; j++) { 
       if(b==0) { 
        myArray[i][j] = vectors[i].getYourArray()[j]; // change made here 
       } else { 
        myArray[j][i] = vectors[i].getYourArray()[j]; // change made here 
       } 
      } 
     } 
    } 
}
