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。

方法一:

package com.Summer_0511.cn;

import java.util.Arrays;

class Student{
private int sNo;
private String sName;
private String sSex;
private int sAge;
private int sJava; public Student(int sNo, String sName, String sSex, int sAge, int sJava) {
super();
this.sNo = sNo;
this.sName = sName;
this.sSex = sSex;
this.sAge = sAge;
this.sJava = sJava;
} public int getsNo() {
return sNo;
} public String getsName() {
return sName;
} public String getsSex() {
return sSex;
} public int getsAge() {
return sAge;
} public int getsJava() {
return sJava;
} @Override
public String toString() {
return "student [sNo=" + sNo + ", sName=" + sName + ", sSex=" + sSex + ", sAge=" + sAge + ", sJava=" + sJava
+ "]";
} } public class Test05 { public static void main(String[] args) {
Student s1 = new Student(1, "小a","男" , 18, 95);
Student s2 = new Student(2,"小b","女",20,90);
Student s3 = new Student(3,"小c","女",21,65);
Student s4 = new Student(4, "小d", "男", 18, 100);
Student s5 = new Student(5, "小e", "男", 15, 85);
int [] s = new int[5];
s[0] = s1.getsJava();
s[1] = s2.getsJava();
s[2] = s3.getsJava();
s[3] = s4.getsJava();
s[4] = s5.getsJava();
int sum = 0;
int Max=s[1],Min=s[1];
for (int i = 0; i < s.length; i++) { sum = sum+s[i]; if (Max < s[i]) {
Max = s[i];
}
if (Min >s[i]) {
Min = s[i];
}
}
System.out.println("java的平均成绩为"+sum/5);
System.out.println("java成绩的最小值"+Min);
System.out.println("java成绩的最大值"+Max); } }

}

this.sAge = sAge;
}
public int getsJava() {
return sJava;
}
public void setsJava(int sJava) {
this.sJava = sJava;
} }
public class Test4 { public static void main(String[] args) {

stus[4] = stu5;
System.out.println("---信息---");
for(int i = 0; i<stus.length;i++){
System.out.println(stus[i].getsNo()+"\t"

+"\t"+stus[i].getsAge()
+"\t"+stus[i].getsJava());
} int sum = 0;
for(int i = 0; i<stus.length;i++){
