java编程的一些编程习题 内附源码答案。。。。。。。系列三

//创建People类
public class TestPeople
{
	public static void main(String args[])
	{
		String s="";
		
		People p1=new People();
		
		s="Name="+p1.getName();
		s=s+"\nAge="+p1.getAge()+"\nGender="+p1.getGender()+"\nHeight="+p1.getHeight()+"\nWeight="+p1.getWeight();
		System.out.println(s);
		
		People.nation="China";
		System.out.println("Nation="+People.nation);
		
		People p2=new People("黎明",18,'M',1.78,73.0);
		
		p2.setNation("HongKong");
		System.out.println("\nName="+p2.getName());
		System.out.println("Age="+p2.getAge());
		System.out.println("Gender="+p2.getGender());
		System.out.println("Height="+p2.getHeight());
		System.out.println("Weight="+p2.getWeight());
	        System.out.println("Nation="+People.nation);
	}
