构建一个学生Student，根据类Student的定义，创建五个该类的对象，输出每个学生的信息，计算并输出这五个学生Java语言成绩的平均值，以及计算并输出他们Java语言成绩的最大值和最小值。

定义一个表示学生信息的类Student，要求如下：

（1）类Student的成员变量：

sNO 表示学号；

sName表示姓名；

sSex表示性别；

sAge表示年龄；

sJava：表示Java课程成绩。

（2）类Student带参数的构造方法：

在构造方法中通过形参完成对成员变量的赋值操作。

（3）类Student的方法成员：

getNo（）：获得学号；

getName（）：获得姓名；

getSex（）：获得性别；

getAge（）获得年龄；

getJava（）：获得Java 课程成绩

根据类Student的定义，创建五个该类的对象，输出每个学生的信息，计算并输出这五个学生Java语言成绩的平均值，以及计算并输出他们Java语言成绩的最大值和最小值。
