我怎么能一般地告诉Java类是原始类型？

Question

Is there any way to take a Class and determine if it represents a primitive type (is there a solution that doesn't require specifically enumerating all the primitive types)?

NOTE: I've seen this question . I'm asking basically the opposite. I have the Class, I want to know if it's a primitive.

Answer 1

Class对象上有一个名为isPrimitive的方法 。

Answer 2

Class.isPrimitive（）会告诉你答案。

Answer 3

This method will also check whether it's a wrapper of a primitive type as well:

/**
* Checks first whether it is primitive and then whether it's wrapper is a primitive wrapper. Returns true
* if either is true
*
* @param c
* @return whether it's a primitive type itself or it's a wrapper for a primitive type
*/
public static boolean isPrimitive(Class c) {
  if (c.isPrimitive()) {
    return true;
  } else if (c == Byte.class
          || c == Short.class
          || c == Integer.class
          || c == Long.class
          || c == Float.class
          || c == Double.class
          || c == Boolean.class
          || c == Character.class) {
    return true;
  } else {
    return false;
  }
