Java定义方法 求3个学生平均成绩及总分

package XUE;
public class student {
	//定义学生类型
		private	String name;
		private float X;
		private float Y;
		private float Z;
		 void setName(String stuname) {//用get方法给私有属性赋值
			 name=stuname;
			 System.out.println("姓名："+name);
		 }
		 void setc(float x) {
			 X=x;

			 System.out.println("国语："+x);
		 }
		 void setm(float y) {
			 Y=y;

                 System.out.println("高数："+y);

		 }
		 void sete(float z) {
			 Z=Z;
			 System.out.println("外语："+z);
		 }
		 //接收考试成绩
		 public float getAverage() {
		 return (X+Y+Z)/3;
		 }
		 public float getSum() {
			return X+Y+Z;
			 
		 }
	}

	package XUE;
         import XUE.student;

        public class test {

	public static void main(String[] args) {
		student s=new student();

		s.setName("谭大");
		s.setc(66);
		s.setm(24);
		s.sete(36);
		//3科成绩传入
		System.out.println("平均分："+s.getAverage());//求平均分
		System.out.println("总分："+s.getSum());
		student s1=new student();

              //创建一个学生对象并赋值
		s1.setName("谭2");
		s1.setc(33);
		s1.setm(85);
		s1.sete(24);
		//3科成绩传入
		System.out.println("平均分："+s1.getAverage());//求平均分
		System.out.println("总分："+s1.getSum());
		student s2=new student();
		s2.setName("谭3");
		s2.setc(90);
		s2.setm(66);
		s2.sete(54);
		//3科成绩传入
		System.out.println("平均分："+s2.getAverage());//求平均分
		System.out.println("总分："+s2.getSum());
	}
