java实现学生成绩录入系统

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); 
       } 
    } 
  } 
}
