有关初始化的问题3

package com.wang.util;

public class Mugs {
	
	Mug mug1;
	Mug mug2;
	{
		mug1=new Mug(22);
		mug2=new Mug(33);
		System.out.println("mug1 & mug2 initialized");
	}

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		System.out.println("inside main()");
		new Mugs();
		System.out.println("new Mugs() completed");
		new Mugs();
		System.out.println("new Mugs() completed");

	}

}


class Mug{
	Mug(int maker){
		System.out.println("Mug("+maker+")");
	}
	
	void f(int maker){
		System.out.println("f("+maker+")");
	}
}

output:

inside main()
Mug(22)
Mug(33)
mug1 & mug2 initialized
new Mugs() completed
Mug(22)
Mug(33)
mug1 & mug2 initialized
new Mugs() completed

 

每new一次就来一次。
