程序：

package dbconf;

 

public class Conf {

       //你还可以定义初始化函数(不能有参数，命名随意)

       public void init(){

              System.out.println("初始化函数");

       }

       public void destroy(){

              System.out.println("消亡函数");

       }

       private String driverClassName;

       private String url;

       

       public String getDriverClassName() {

              return driverClassName;

       }

       public void setDriverClassName(String driverClassName) {

              this.driverClassName = driverClassName;

       }

       public String getUrl() {

              return url;

       }

       public void setUrl(String url) {

              this.url = url;

       }

       public void printInfo(){

              System.out.println(this.driverClassName);

              System.out.println(this.url);

       }

}
