class Student {
int age;
String name;
static int count;

public Student() {
System.out.println(“in constructor”);
}
/*只执行一次。*/
static {
System.out.println(“hello”);
count = 0;
}
}

public class Test {
public static void main(String[] args) {
Student s = new Student();
Student s1 = new Student();
}
}

result is :

hello
in constructor
in constructor

assignment: class: School has a static member called count which records how many schools we have. count’s initial value is 0, count increments in School’s constructor.

assignment2: car( mercedes, BMW, static member count is increased in the constructor.)
