我想要把数据写入新建的stu.txt中。该怎样改一下主函数呢？各位大神可以帮忙写个范例吗？
package test0601;public class Student { private String sname; private long sno; private int score1; private int score2; public String getSname() { return sname; } public void setSname(String sname) { this.sname = sname; } public long getSno() { return sno; } public void setSno(long sno) { this.sno = sno; } public int getScore1() { return score1; } public void setScore1(int score1) { this.score1 = score1; } public int getScore2() { return score2; } public void setScore2(int score2) { this.score2 = score2; } }
import java.util.*;public class test { public static void main(String[] args) { Student[] stu = new Student[5]; Scanner s = new Scanner(System.in); for(int i=0;i<5;i++) { stu[i] = new Student(); System.out.printf("请输入第%d名学生姓名： ", i+1); stu[i].setSname(s.nextLine()); System.out.printf("请输入第%d名学生学号： ", i+1); stu[i].setSno(s.nextLong()); System.out.printf("请输入第%d名学生高数成绩： ", i+1); stu[i].setScore1(s.nextInt()); System.out.printf("请输入第%d名学生物理成绩： ", i+1); stu[i].setScore2(s.nextInt()); s.nextLine(); } System.out.printf("所有学生信息：\n"); for(int i=0;i<5;i++) { System.out.printf("%20s%20s%20s%20s\n", "姓名", "学号", "高数", "物理"); System.out.printf("%10s%10s%10s%10s\n", stu[i].getSname(), stu[i].getSno(), stu[i].getScore1(), stu[i].getScore2()); } }}
