【基础】通过反射访问private成员和方法，private设计的

package com.test.reflect;

import java.lang.reflect.Method;

public class DemoPrivateInvoke {
	public static void main(String[] args) {
		printMethodPrivateInvoke(new Some());
	}
	
	public static void printMethodPrivateInvoke(Object obj) {
		Class c1 = obj.getClass();
		try {
			Method dm = c1.getDeclaredMethod("doSomingPrivate");
			dm.setAccessible(true);
			dm.invoke(obj);
		} catch (Exception e) {
			e.printStackTrace();
		}
	}
}

package com.test.reflect;

public class Some {
	public static String str3;
	private int num1;
	private String str1;
	public int num2;
	public String str2;
	
	public void doSoming() {
		System.out.println("doSoming");
	}
	
	private void doSomingPrivate() {
		System.out.println("doSomingPrivate");
	}
}
