初学Java4：从键盘录入学生信息(仅姓名和成绩)并输出

//从键盘录入学生信息(仅姓名和成绩)并输出。public class StuInformation {//此处命名用StuScore可能更恰当 String name; double score;}import java.util.Scanner;

public class TextStuInformation {

	public static void main(String[] args) {
		Scanner sc = new Scanner(System.in);
		int i = 0, j = 0;
		// 信息录入
		System.out.print("请输入您要录入的学生个数：");
		int num = sc.nextInt();
		StuInformation Stu[] = new StuInformation[num];
		for (i = 0; i < Stu.length; i++) {
			Stu[i] = new StuInformation();
			System.out.print("请输入第" + (i + 1) + "个学生的姓名：");
			Stu[i].name = sc.next();
			System.out.print("请输入第" + (i + 1) + "个学生的成绩：");
			Stu[i].score = sc.nextDouble();
		}
		// 信息输出
		System.out.println("\t姓名\t成绩");
		for (StuInformation stuInformation : Stu) {
			System.out.println("\t" + stuInformation.name + "\t" + stuInformation.score);
		}
		double max = 0, min = 0;
		int cont = 0;
		// 判断最高分
		for (i = 0; i < Stu.length; i++) {
			if (max < Stu[i].score) {
				max = Stu[i].score;
				
				cont = i;//用来记录最高成绩的同学的name
				
			}
		}
		System.out.println("最高分是:" + Stu[cont].name +","+ max);
		// 判断最低分
		min = Stu[0].score;
		for (j = 0; j < Stu.length; j++) {
			if (min >= Stu[j].score) {
				min = Stu[j].score;
				cont = j;//用来记录最低成绩的同学的name
			}
		}
		System.out.println("最低分是:" + Stu[cont].name +","+ min);
		sc.close();
	}
}
