学生成绩包括平时成绩和考核成绩，总评成绩=平时成绩*50%+考核成绩*50%，每个学生都可以按照“姓名：平时成绩 总评成绩”的格式显示自己的信息。

摘要：
  用Java类的定义，类的成员变量

参考代码：

package com.gx.demo;

public class Student {
	private String name;//姓名
	private int pacificScore;//平时成绩
	private int totalScore;//总评成绩	
	
	//有参构造方法
	public Student(String name, int pacificScore, int totalScore) {
		this.name=name;
		this.pacificScore=pacificScore;
		this.totalScore=totalScore;
	}

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}

	public int getPacificScore() {
		return pacificScore;
	}

	public void setPacificScore(int pacificScore) {
		this.pacificScore = pacificScore;
	}

	public int getTotalScore() {
		return totalScore;
	}

	public void setTotalScore(int totalScore) {
		this.totalScore = totalScore;
	}
	
}

package com.gx.demo;

import java.util.ArrayList;
import java.util.List;

public class Test7 {	
	/**
	 * 总评成绩
	 * @param pacificScore	平时成绩
	 * @param checkScore	考核成绩
	 * @return
	 */
	public static int getTotalScore(int pacificScore, int checkScore) {
		int totalScore=(int) (pacificScore*0.5 + checkScore*0.5);
		return totalScore;
	}
	
	public static void main(String[] args) {
		//调用Student类中的构造方法
		Student student1=new Student("张三", 80, getTotalScore(80,76));
		Student student2=new Student("李四", 76, getTotalScore(76,70));
		Student student3=new Student("王五", 84, getTotalScore(84,68));
		Student student4=new Student("宋六", 82, getTotalScore(82,60));
		Student student5=new Student("钱七", 68, getTotalScore(68,74));
		
		List<Student> list=new ArrayList<Student>();
		list.add(student1);
		list.add(student2);
		list.add(student3);
		list.add(student4);
		list.add(student5);
		
		for (Student student : list) {
			String name = student.getName();
			int pacificScore = student.getPacificScore();
			int totalScore = student.getTotalScore();			
			System.out.println("姓名："+name+";\t平时成绩："+pacificScore+";\t总评成绩："+totalScore);
		}		
	}
}

输出结果：

姓名：张三;	平时成绩：80;	总评成绩：78
姓名：李四;	平时成绩：76;	总评成绩：73
姓名：王五;	平时成绩：84;	总评成绩：76
姓名：宋六;	平时成绩：82;	总评成绩：71
姓名：钱七;	平时成绩：68;	总评成绩：71
