java - 在 Java 中运行程序时输出未完全显示

Question

我正在使用BlueJ，供引用。

程序编译并运行良好。

问题是输出没有输出全部内容。

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

正如我的主类 WorkerApp 所示，输出大约还有三分之一。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。

import java.io.*;

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

这是主要类之一，Company:

private final int InitialCapacity = 7;
private int employCount;

/**

    employCount = 0;
}

    for (int i = 0; i < employCount; i++){
        if (employeeArray[i].getName().equals(name)){

        }

    return -1;
}

/**

            throw new RuntimeException ("The Employee Is Not New");
        }
    }

    if (employeeArray.length == employCount){
        expand();
    }

    employeeArray[index] = employ;
    employCount++;
    return index;
}

/**

        return;
    }

    for (int i = index; i < employCount - 1; i++){
        employeeArray[i] = employeeArray[i + 1];

提前谢谢您!

似乎您必须扩展 BlueJ as shown here. 中输出的行号

“在 BlueJ 终端窗口中，转到 Options 并打开 Unlimited Buffering。这将解决您的问题。您还可以在方法调用时打开 Clear Screen 以进行以下操作:每个程序都在清晰的屏幕上运行。” - 极限编码员
