Question

我一直很难把这个项目放在一起。我们的想法是用实例变量和扫描仪计算课堂上学生的平均成绩。我理解作业的输出和输入部分，但我正在努力编写下面的代码。

public class Averages extends Object 
{

// Put any attributes / instance variables here. */
private String name;
// create grade1, grade2, and your Scanner.

// Constructor 
public Classroom () 
{
  // initialize any attributes that need initial values here */
  // initialize your Scanner
  return;
}

然后一旦创建，我应该修改我的原始编码，以便它使用实例变量而不是参数变量。这是我最初的原因：

public double calcAverage (double a, double b) 
{
  return ((a + b) /2.0); 
}

Answer 1

public class Averages extends Object 
{

    // Put any attributes / instance variables here. 

    private String name;

    // create grade1, grade2, and your Scanner.

    // Constructor must have the same name as the class

    public Averages() 
    {

    // initialize any attributes that need initial values here ` 

    // initialize your Scanner

    }
}

I simply corrected your constructor, the constructor name must match the classname

初始化实例变量以及属性和扫描程序
