【问题描述】：
我用的是BlueJ，供参考。
程序编译运行良好。
问题是输出没有输出整个东西。
这是当前的输出：
H Sanders,HarlandDavid 277651 8.72 false
S Baron,James 368535 310236.0
S Moran,Blake 123456 260000.0
H Bob,Billy 654321 15.0 false
H Smith,Will 345612 10.5 true 30
6) Remove a worker who is NOT in the list
The Employee is not Found
7) Remove a worker who is the first in the list
H MacDonald,Ronald 386218 7.8 true 40
H Walton,Samuel 268517 8.21 false
H Thomas,David 131313 9.45 true 38
H Sanders,HarlandDavid 277651 8.72 false
S Baron,James 368535 310236.0
S Moran,Blake 123456 260000.0
H Bob,Billy 654321 15.0 false
H Smith,Will 345612 10.5 true 30
8) Find a worker who is the middle of the list
Found at 4
9) Find a worker who is NOT in the list
Found at -1
10) Find the weekly salary of a worker who is salaried
5000.0
11) Find the weekly salary of an hourly worker who has no overtime allowed [50 hours]
750.0
12) Find the weekly salary of an hourly worker who has overtime allowed [50 hours]
630.0
13) Find the weekly salary of an hourly worker who has overtime allowed [20 hours]
210.0
14) Print the sorted list
H MacDonald,Ronald 386218 7.8 true 40
H Walton,Samuel 268517 8.21 false
H Thomas,David 131313 9.45 true 38
H Sanders,HarlandDavid 277651 8.72 false
S Baron,James 368535 310236.0
S Moran,Blake 123456 260000.0
H Bob,Billy 654321 15.0 false
H Smith,Will 345612 10.5 true 30
15) End the process
正如我的主要课程WorkerApp 所示，输出大约多出三分之一。相反，输出从 5) 的中间开始并显示其余部分，而不输出 5) 之前的内容。

如果有帮助，这是它读取的文本文件：
S Washington,George 000001 125000
H MacDonald,Ronald 386218 7.80 true 40
H Walton,Samuel 268517 8.21 false
H Thomas,David 131313 9.45 true 38
H Sanders,HarlandDavid 277651 8.72 false
S Baron,James 368535 310236
这是主要课程之一，Company：
import java.io.*;
import java.util.*;
public class Company{
private Employee[] employeeArray;
private final int InitialCapacity = 7;
private int employCount;
/**
* Creates the employee array and sets employCount to 0.

public Company(){

employCount = 0;
}
/**
* Finds an employee in the list.
*/
public int find(String name){
for (int i = 0; i < employCount; i++){
if (employeeArray[i].getName().equals(name)){
return i;
}
}
return -1;
}
/**

*/
public int add(Employee employ){
int index;
for (index = 0; index < employCount; index++){
int result = employeeArray[index].getName().compareTo(employ.getName());
if(result == 0){
throw new RuntimeException ("The Employee Is Not New");
}
}
if (employeeArray.length == employCount){
expand();
}
employeeArray[index] = employ;
employCount++;
return index;
}
/**

*/
public void remove(String name){
int index = find(name);
if (index == -1){
System.out.println("The Employee is not Found");
return;
}
for (int i = index; i < employCount - 1; i++){
employeeArray[i] = employeeArray[i + 1];
}
employCount--;
}
/**

*/
public void print(){
if(employCount == 0){
System.out.println("The List is Empty");
return;
}
for(int i = 0; i < employCount; i++){
System.out.println(employeeArray[i]);
}
}
/**

*/
private void expand(){
Employee[] newArray = new Employee[employeeArray.length + InitialCapacity];
for (int i = 0; i < employeeArray.length; i++){

}
提前谢谢你！
