程序的解题规范,
1,注意setter,getter的使用。
2,方法不要直接输出,而是交给被调用处输出
题目:
class Student{
private String stuno ;
private String name ;
private float math ;
private float english ;
private float computer ;
public Student(){}
public Student(String s,String n,float m,float e,float c){
this.setStuno(s) ;
this.setName(n) ;
this.setMath(m) ;
this.setEnglish(e) ;
this.setComputer(c) ;
}
public void setStuno(String s){
stuno = s ;
}
public void setName(String n){
name = n ;
}
public void setMath(float m){
math = m ;
}
public void setEnglish(float e){
english = e ;
}
public void setComputer(float c){
computer = c ;
}
public String getStuno(){
return stuno ;
}
public String getName(){
return name ;
}
public float getMath(){
return math ;
}
public float getEnglish(){
return english ;
}
public float getComputer(){
return computer ;
}
public float sum(){ // 求和操作
return math + english + computer ;
}
public float avg(){ // 求平均值
return this.sum() / 3 ;
}
public float max(){ // 求最高成绩
float max = math ; // 数学是最高成绩
max = max>computer?max:computer ;
max = max>english?max:english ;
return max ;
}
public float min(){ // 求最低成绩
float min = math ; // 数学是最高成绩
min = min<computer?min:computer ;
min = min<english?min:english ;
return min ;
}
};
public class ExampleDemo01{
public static void main(String args[]){
Student stu = null ; // 声明对象
stu = new Student("MLDN-33","李兴华",95.0f,89.0f,96.0f) ;
System.out.println("学生编号:" + stu.getStuno()) ;

System.out.println("数学成绩:" + stu.getMath()) ;
System.out.println("英语成绩:" + stu.getEnglish()) ;
