本文为大家分享了java实现学生成绩录入系统,供大家参考,具体内容如下
1.学生类,包括学生的姓名和各科成绩
public class score { public string name; public double englishgrade, mathgrade,phyicalgrade, chemicalgrade,biologicalgrade; score() { } public score(string name,double englishgrade, double mathgrade,double phyicalgrade, double chemicalgrade,double biologicalgrade){ this.name = name; this.englishgrade = englishgrade; this.mathgrade = mathgrade; this.phyicalgrade = phyicalgrade; this.chemicalgrade = chemicalgrade; this.biologicalgrade = biologicalgrade; } }
2.对学生类进行设置,包括设置查找等
package score; public class scorezip { score[] s = new score[5]; public void setdata(score name, int index) {//添加成绩类到成绩数组中 s[index] = name; } public score[] getdata() { //返回学生数组 return s; } public score serchdata(string name) { //查找学生各科成绩 for (int index = 0; index < s.length; index++) { if (name !=null && s[index] != null ) if (s[index].name.equals(name)){ return s[index]; } } return null; } }
3.学生成绩录入及学生成绩清单
package score; import java.util.scanner; public class scorezip2 { public static void main(string[] arr) { scanner sc = new scanner(system.in); scorezip sr = new scorezip(); for (int i = 0; i < 5; i++) { //这里定义长度为五的学生成绩表 system.out.println("输入学生姓名:"); string name = sc.next(); if (name.equals("n")) { break; } system.out.println("英语分数:"); double english = sc.nextdouble(); system.out.println("数学分数:"); double math = sc.nextdouble(); system.out.println("物理分数:"); double physical = sc.nextdouble(); system.out.println("化学分数:"); double chemical = sc.nextdouble(); system.out.println("生物分数:"); double biology = sc.nextdouble(); score s = new score(name, english,math,physical,chemical,biology); sr.setdata(s, i); } system.out.println("=========================================" + "学生成绩表======================================"); system.out.println("姓名\t\t英语成绩\t\t数学成绩\t\t物理成绩\t\t化学成绩\t\t生物成绩"); score[] b = sr.getdata(); for (score s : b) { if (s == null) { break; } system.out.println(s.name + "\t\t" + s.englishgrade+"\t\t"+s.mathgrade +"\t\t"+s.phyicalgrade+"\t\t"+s.chemicalgrade+"\t\t"+s.biologicalgrade); } system.out.println("是否查找学生成绩? 是y 否n"); string flag = sc.next(); if(flag.equals("y")){ system.out.println("输入要查找的学生名:"); string name = sc.next(); score s = sr.serchdata(name); if (s == null) { system.out.println("对不起,没有此学生名"); } else { double mg = s.mathgrade; double eg = s.englishgrade; double pg = s.phyicalgrade; double cg= s.chemicalgrade; double bg = s.biologicalgrade; double submit = mg+eg+pg+cg+bg; system.out.println("要查找的学生为:" + name + "\n数学成绩为:" + mg + "\n英语成绩为:" + eg+ "\n物理成绩为:" + pg+ "\n化学成绩为:" + cg + "\n生物成绩为:" + bg+ "\n总成绩成绩为:" + submit); } } } }
