运行错误/对象没有输入到数组

Question

我写了这个程序，它没有错误地完成，但是当我输入（name-age-id）应该是一个对象时它没有输入到数组中！ 有谁可以告诉我问题在哪里？ :(

public class ClientClass { 
     public static Scanner read = new Scanner(System.in); 


     public static void main(String[] args) { 

      while (true) {

       char f = read.next().charAt(0); 
       Kindergarten k = new Kindergarten("baby", 10); 


       if (f == 'a') { 

        System.out.println("enter the name :"); 
        String name1 = read.next(); 
        System.out.println("enter the id number :"); 
        int id1 = read.nextInt(); 

        BABY b = new BABY(name1, id1); 

        System.out.println("enter the age :"); 
        int age1 = read.nextInt(); 
        b.setage(age1); 
        k.add_b(b); 

       } 

       if (f == 'b') { 
        int v = -1; 
        System.out.println("enter the id number"); 
        int id1 = read.nextInt(); 

        v = k.srch_b(id1); 
        if (v == -1) 
         System.out.println("baby not found"); 
        else 
         System.out.println(k.toString()); 
       }//there is somthing miss 


       if (f == 'c') { 
        System.out.println("enter the id number"); 
        int id1 = read.nextInt(); 
        k.del_b(id1);

尝试做到这一点

class Kindergarten { 
    private String name; 
    private int currnt =0; 
    private BABY arr[];...
