Eclipse警告 - 类是原始类型。对泛型类型的引用< T>应该参数化 [英] Eclipse warning - Class is a raw type. References to generic type Class<T> should be parameterized

问题描述

  import java.util.ArrayList; 
 
 public class ListOfClasses 
 {
 
 private ArrayList< Class>班; 
 
 public ArrayList< Class> getClasses（）
 {
返回类; 
 
 
 public void setClasses（ArrayList< Class> class）
 {
 this.classes = classes; 
 
 
 
 
 $ b $ p 
 $ b 
为此，我在eclipse中得到以下警告 -  
 
 
 
 
类是一种原始类型。引用泛型类应该是
参数化的
 
这是在 previous question ，但答案只针对Spring框架。但即使与Spring没有任何关系，我也会收到这个警告。那么问题是什么？
解决方案
我怀疑它抱怨Class是原始类型。您可以尝试 
 
 
  private List< Class<>>班; 
  
或者取消这个特殊警告。  
 
 
在这种情况下，我会忽略警告。 
  private final List< Class> classes = new ArrayList<>（）; 
 
公共列表< Class> getClasses（）{
返回类; 
 
 
 public void setClasses（List< Class> classes）{
 this.classes.clear（）; 
 this.classes.addAll（classes）; 
} 
  
 
import java.util.ArrayList;

public class ListOfClasses
{

    private ArrayList<Class> classes;

    public ArrayList<Class> getClasses() 
    {
        return classes;
    }

    public void setClasses(ArrayList<Class> classes) 
    {
        this.classes = classes;
    }
}
For this, I get the following warning in eclipse - 

  
Class is a raw type. References to generic type Class should be
  parameterized
This was asked in an earlier question, but the answer was specific to the Spring Framework. But I am getting this warning even without having anything to do with Spring. So what is the problem?
解决方案
I suspect its complaining that Class is a raw type. You can try
private List<Class<?>> classes;
or suppress this particular warning.


I would ignore the warning in this case.  I would also consider using a defensive copy.
private final List<Class> classes = new ArrayList<>();

public List<Class> getClasses() {
    return classes;
}

public void setClasses(List<Class> classes) {
    this.classes.clear();
    this.classes.addAll(classes);
}
