Java-static用法

public class TestStatic {
int id;
String name;
String pwd;

static String company ="杭州阿里巴巴";

public TestStatic(int id,String name){
	
	this.id = id;
	this.name=name;	
}

public void login(){
	PrintCompany();
	System.out.println("company");
	System.out.println("登陆："+name);
}

public static void PrintCompany(){
	//login(); //调用非静态成员变量，编译就会报错
	System.out.println(company);
}

public static void main(String[] args){
	TestStatic  u= new TestStatic(101,"李寻欢");
	u.PrintCompany();//这里会报错
	System.out.println("###########");
	u.company="深圳腾讯";
	TestStatic.PrintCompany();
	System.out.println("###########");
	TestStatic.company="杭州网易";
	TestStatic.PrintCompany();
}
}
