getDeclaringClass()方法getDeclaringClass()方法在java.lang包中可用。
getDeclaringClass()方法用于返回声明的Class对象，该对象表示在此Class表示的该类或接口是其他类的一部分或成员时在其中进行声明的Class。
getDeclaringClass()方法是一个非静态方法，仅可通过类对象访问，如果尝试使用类名称访问该方法，则会收到错误消息。
返回Class对象时，getDeclaringClass()方法不会引发异常。
语法：
public Class getDeclaringClass ();
参数：
它不接受任何参数。
返回值：
此方法的返回类型为Class，它从该Class返回一个声明的class的对象。
注意：
当该类或接口不是其他类的一部分或成员时，将返回null。
当此类反映原始类型或void类型或数组类时，将返回null。
示例
//Java程序演示示例
//类的ClassgetDeclaringClass()方法
import java.lang.reflect.*;
public class GetDeclaringClassOfClass {
public static void main(String[] args) {
//返回Class对象
//给定的类名
Class cl = Integer.class;
//它返回一个方法数组
//表示私有，受保护，公共和默认
//类Integer-
Method[] methods = cl.getMethods();
//遍历整数类
for (int i = 0; i < methods.length; ++i) {
Class declare_classes = methods[i].getDeclaringClass();
System.out.print(" Declaring Methods Class: ");
System.out.println(declare_classes.toString());
}
}
}输出结果
