java实现整个工程全局变量的方法

public class Project {
//全局变量
public static String project_name;
public static String project_softwaretype;
public static String project_development;
public static String project_language;
public static String project_dataaddress;
public static String project_timeunit;
public static String project_datatype;

}

1.定义一个public的类

2.成员变量为static

3.赋值后直接Project。project_name就可以在整个工程中使用该值
