public class HelloWorld { String name; String sex; static int age; public void HelloWorld () { System.out.println("通過(guò)構(gòu)造方法初始化name"); name = "tom"; } { System.out.println("通過(guò)初始化塊初始化sex"); sex = "男"; } { System.out.println("通過(guò)靜態(tài)初始化塊初始化age"); age = 20; } public void show() { System.out.println("姓名：" + name + "，性別：" + sex + "，年齡：" + age); } public static void main(String[] args) { HelloWorld hello = new HelloWorld(); Hello.show()； }}
