在Java中編寫程序，定義一個(gè)學(xué)生類，屬性包括姓名，學(xué)號(hào)，語文成績，數(shù)學(xué)成績，英語成績，方法包括輸出數(shù)
public class Student(){
private int stuid; ? ? ? ? ? ? ? //學(xué)號(hào)
private String name; ? ? //姓名
private?double languagescore; ?//語文成績
private?double?mathscore; ?//數(shù)學(xué)成績
private?double?englishscore; ?//英語成績
?public int getStuid() {
? ? ? ? return stuid;
? ? }
? ? public void setStuid(int stuid) {
? ? ? ? this.stuid = stuid;
? ? }
? ? public String getName() {
? ? ? ? return name;
? ? }
? ? public void setName(String name) {
? ? ? ? this.name = name;
? ? }
? ? public double getLanguagescore() {
? ? ? ? return languagescore;
? ? }
? ? public void setLanguagescore(double languagescore) {
? ? ? ? this.languagescore = languagescore;
? ? }
? ? public double getMathscore() {
? ? ? ? return mathscore;
? ? }
? ? public void setMathscore(double mathscore) {
? ? ? ? this.mathscore = mathscore;
? ? }
? ? public double getEnglishscore() {
? ? ? ? return englishscore;
? ? }
? ? public void setEnglishscore(double englishscore) {
? ? ? ? this.englishscore = englishscore;
? ? }
public void total(){
System.out.println(總成績：+(this.languagescore+this.mathscore+this.englishscore));
}
public void avgscore(){
System.out.println(平均成績：+(this.languagescore+this.mathscore+this.englishscore)/3);
}
}
