public class Proson {
	String name;
	int age;
	double height;
	void sayHello(){
		System.
out.println(name+","+age+"歲,"+"身高"+height); } } `` ```java public class PersonCreate { public static void main(String[] args) { Proson p1 = new Proson(); p1.name = "zhangsan"; p1.age = 33; p1.height = 1.73; p1.sayHello(); Proson p2 = new Proson(); p2.name = "lisi"; p2.age =
44; p2.height = 1.74; p2.sayHello(); } }
