下面是我的代码，重点是案例1和案例2。考虑到我是一个初学者，请建议一些简单的方法来接受全名：
package Tester;

import com.app.org.Worker;
public class TestOrganization {
public static void main(String args[]) {
Scanner sc = new Scanner(System.in);
System.out.println("How many people you want to recruit");
Emp[] org = new Emp[sc.nextInt()]; //holder array ...its not a emp object...its array type of object
boolean exit = false;
int index = 0;
while(!exit) {
System.out.println("Optionsn"+"1.Hire Managern"+"2.Hire Workern"+"3.Display information of all employeesn"
+ "4.Update Performance Bonus or Hourly Rate");
switch (sc.nextInt()) {
case 1:{
if(index<org.length && index>=0) {
System.out.println("Manager Details: id, name, deptId, basic, performBonus");
org[index++] = new Mgr(sc.nextInt(),sc.nextLine(),sc.next(),sc.nextDouble(),sc.nextInt());
}else {
System.out.println("Invalid!!! index");
}
break;
}
case 2:{
if(index<org.length && index>=0) {
System.out.println("Worker Details: id, name, deptId, basic, hw, hr");
org[index++] = new Worker(sc.nextInt(),sc.nextLine(),sc.next(),sc.nextDouble(),sc.nextDouble(),sc.nextDouble());
}else System.out.println("invalid!!! index");
break;
}
case 3:{
System.out.println("Employees Details");
for (Emp e : org) {
if(e!=null)
System.out.println(e);
}
}

混合nextInt/nextDouble/。。。使用来自扫描仪的nextLine总是一个坏主意。nextInt/nextDouble/。。。在Stream上保留一个换行符，这意味着当调用nextLine时，它只会拾取换行符，而这可能不是您想要的
除了我所评论的内容之外，您还可以尝试读取分隔行上的每个输入，使用Integer.parseInt(read.nextLine())表示整数，Double.parseDouble()表示双精度。
用于常规字符串输入的read.nextLine()
实际参数列表和正式参数列表的长度构造函数java不同。最好先使用nextLine((，然后再使用其余部分。
示例：-
class Codechef
{
public static void main (String[] args) throws java.lang.Exception
{
// your code goes here
Scanner sc = new Scanner(System.in);
Mgr obj = new Mgr(sc.nextLine(), sc.nextDouble(), sc.nextInt());
}
}
class Mgr{
public Mgr(String name, Double dNo, int id ){
System.out.println(id +" and "+ name +"dNo "+ dNo);
}
}
