该系统通过控制台输入查找特定学生的信息，并统计英语、体育和数学成绩不及格的学生人数。使用Java编程，通过Scanner类读取用户输入，然后遍历学生数组进行匹配和统计。

public class Stu {
	
	public static void main(String[] args) {
		System.out.println("请输入要查找的学生名字：");

		String Preson=scanner.next();
		
		StudentManager[]student=new StudentManager[5];
		student[0]=new StudentManager(01,"李1",28,89,30);
		student[1]=new StudentManager(02,"罗2",64,44,45);
		student[2]=new StudentManager(03,"张3",74,56,17);
		student[3]=new StudentManager(04,"卢4",55,68,97);
		student[4]=new StudentManager(05,"王5",97,38,73);		
		int num1 = 0;
		int num2 = 0;
		int num3 = 0;
