【自动化__持续集成】___java___static

一、代码如下

package www.wujianbotwo;

public class Demo4 {
	public static void main(String[] args) {
		Demo4 demo4= new Demo4();
		
	}
	
	static {
		System.out.println("static语句执行");
	}
	
	public Demo4() {
		// TODO Auto-generated constructor stub
		System.out.println("Demo4构造语句执行");
	}
}

package www.wujianbotwo;

public class Demo4 {
	public static void main(String[] args) {
		Demo4 demo4= new Demo4();
		Demo4 demo5= new Demo4();
		
	}
	
	static {
		System.out.println("static语句执行");
	}
	
	public Demo4() {
		// TODO Auto-generated constructor stub
		System.out.println("Demo4构造语句执行");
	}
}

package www.wujianbotwo;

public class Demo4 {
	public static void main(String[] args) {
		Demo4 demo4= new Demo4();
		Demo4 demo5= new Demo4();
		System.out.println(demo4);
		
	}
	
	static {
		System.out.println("static语句执行");
	}
	
	public Demo4() {
		// TODO Auto-generated constructor stub
		System.out.println("Demo4构造语句执行");
	}
}

package www.wujianbotwo;

public class Demo5 {
	static int age=-1;

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		Demo5 demo5= new Demo5();
		demo5.age=9;
		System.out.println(demo5.age);
		Demo5 demo6= new Demo5();
		demo5.age=40;
		System.out.println(demo5.age);

	}
