其实类的设计可以由powerdesigner来完成，这里就不做介绍了饿。。。

class Student{

private float computerScore;
private float mathScore;
private float englishScore;

public Student(float computerScore,float mathScore,float englishScore){

  this.setComputerScore(computerScore);
  this.setMathScore(mathScore);
  this.setEnglishScore(englishScore);
}

public void setComputerScore(float computerScore){

this.computerScore=computerScore;
}

public float getComputerScore(){

return this.computerScore;
}

public void setMathScore(float mathScore){

this.mathScore=mathScore;
}

public float getMathScore(){

return this.mathScore;
}

public void setEnglishScore(float englishScore){

this.englishScore=englishScore;
}

public float getEnglishScore(){

return this.englishScore;
}

public float getSum(){

return computerScore+mathScore+englishScore;
}

public float getAverage(){

return this.getSum()/3;
}

public float getMaxScore(){

  float maxScore=computerScore>mathScore ? computerScore:mathScore;
  maxScore=maxScore>englishScore ? maxScore:englishScore;
  return maxScore;
}

public float getMinScore(){

  float minScore=computerScore<mathScore ? computerScore:mathScore;
  minScore=minScore<englishScore ? minScore:englishScore;
  return minScore;
}

public String getInfo(){

  return "学生成绩信息:/n"+
     "计算机技术:"+this.getComputerScore()+"/n"+
     "数      学:"+this.getMathScore()+"/n"+
     "英      语:"+this.getEnglishScore()+"/n";

}

}

public class StudentDemo01{

public static void main(String[]args){

  Student student=new Student(90f,89f,65f);
  System.out.println("总分:"+student.getSum());
  System.out.println("平均分:"+student.getAverage());
  System.out.println("最高分:"+student.getMaxScore());
  System.out.println("最低分:"+student.getMinScore());
  System.out.println(student.getInfo());
}
}

程序运行结果：

C:/mldn>javac StudentDemo01.java

C:/mldn>java StudentDemo01
