Java 如何减少混乱？

我正在写一个程序，用户在数组中输入8个不同的员工年龄和期望的退休年龄，然后显示这些信息以及他们退休的年数。这是我的密码：

import java.util.Scanner;

public class Retirement {

public static void main(String[] args) {
Scanner input = new Scanner(System.in); 

    int[][] ages = new int[8][2];
    System.out.println("Enter the employees current ages (between 19 and 70), and enter their desired retirement ages (62, 66, or 70).");
    for (int i = 0; i < ages.length; i++) {
        ages[i][0] = input.nextInt();
        ages[i][1] = input.nextInt();
        }
    int employee1 = (ages[0][1] - ages[0][0]);
    int employee2 = (ages[1][1] - ages[1][0]);
    int employee3 = (ages[2][1] - ages[2][0]);
    int employee4 = (ages[3][1] - ages[3][0]);
    int employee5 = (ages[4][1] - ages[4][0]);
    int employee6 = (ages[5][1] - ages[5][0]);
    int employee7 = (ages[6][1] - ages[6][0]);
    int employee8 = (ages[7][1] - ages[7][0]);

    System.out.println("The current age and desired retirement age for Employee #1 is: " + (ages[0][0]) + " and " + (ages[0][1]) + ".");
    System.out.println("Employee #1 has to work " + (employee1) + " years before they can retire.");

    System.out.println("\nThe current age and desired retirement age for Employee #2 is: " + (ages[1][0]) + " and " + (ages[1][1]) + ".");
    System.out.println("Employee #2 has to work " + (employee2) + " years before they can retire.");

    System.out.println("\nThe current age and desired retirement age for Employee #3 is: " + (ages[2][0]) + " and " + (ages[2][1]) + ".");
    System.out.println("Employee #3 has to work " + (employee3) + " years before they can retire.");

    System.out.println("\nThe current age and desired retirement age for Employee #4 is: " + (ages[3][0]) + " and " + (ages[3][1]) + ".");
    System.out.println("Employee #4 has to work " + (employee4) + " years before they can retire.");

    System.out.println("\nThe current age and desired retirement age for Employee #5 is: " + (ages[4][0]) + " and " + (ages[4][1]) + ".");
    System.out.println("Employee #5 has to work " + (employee5) + " years before they can retire.");

    System.out.println("\nThe current age and desired retirement age for Employee #6 is: " + (ages[5][0]) + " and " + (ages[5][1]) + ".");
    System.out.println("Employee #6 has to work " + (employee6) + " years before they can retire.");

    System.out.println("\nThe current age and desired retirement age for Employee #7 is: " + (ages[6][0]) + " and " + (ages[6][1]) + ".");
    System.out.println("Employee #7 has to work " + (employee7) + " years before they can retire.");

    System.out.println("\nThe current age and desired retirement age for Employee #8 is: " + (ages[7][0]) + " and " + (ages[7][1]) + ".");
    System.out.println("Employee #8 has to work " + (employee8) + " years before they can retire.");
}

}

import java.util.Scanner；
公营退休{
公共静态void main（字符串[]args）{
扫描仪输入=新扫描仪（System.in）；
int[][]年龄=新int[8][2]；
System.out.println（“输入员工当前年龄（19到70岁之间），并输入他们期望的退休年龄（62、66或70岁）。”；
for（int i=0；i

现在，我想弄清楚的是，它们是否可能是减少一些混乱的一种方法，但我不确定我是否可以，或者它是否必须占用空间。这两种方式都无所谓，但我希望它看起来更流线型，而不是那么凌乱。谢谢你的帮助

我将首先创建一个数组

employee

，然后从那里创建for循环。

您似乎已经能够使用for循环了，因此重构此代码应该不是问题：

Scanner input = new Scanner(System.in);

int[][] ages = new int[8][2];
int[] employees = new int[8];
System.out.println("Enter the employees current ages (between 19 and 70), and enter their desired retirement ages (62, 66, or 70).");
for (int i = 0; i < ages.length; i++) {
    ages[i][0] = input.nextInt();
    ages[i][1] = input.nextInt();
}
for (int i = 0 ; i < employees.length ; i++) {
    employees[i] = (ages[i][1] - ages[i][0]);
}

for (int i = 0 ; i < employees.length ; i++) {
    System.out.println("The current age and desired retirement age for Employee #" + (i + 1) + " is: " + (ages[i][0]) + " and " + (ages[i][1]) + ".");
    System.out.println("Employee #" + (i + 1) + " has to work " + (employees[i]) + " years before they can retire.");
}

您是否意识到，附加了

*

的部件似乎每次增加一个，而所有其他部件保持不变？这意味着我们可以将其转换为for循环：

for (int i = 0 ; i < employees.length ; i++) {
    employees[i] = (ages[i][1] - ages[i][0]);
}

同样，你会看到一些数字在一个接一个地增加，而其他的一切都保持不变。我们也可以将其更改为for循环：

for (int i = 0 ; i < employees.length ; i++) {
    System.out.println("The current age and desired retirement age for Employee #" + (i + 1) + " is: " + (ages[i][0]) + " and " + (ages[i][1]) + ".");
    System.out.println("Employee #" + (i + 1) + " has to work " + (employees[i]) + " years before they can retire.");
}

for（int i=0；i

---

但是，员工人数并没有从0增加到7。相反，它是从1到8。这就是为什么它是

“Employee#”+（i+1）

而不是

“Employee#”+i

它看起来像java，而不是javascript。老实说，我不知道它们之间有什么区别。我使用的是eclipse，很可能是Java，而不是javascript，抱歉。这有点奇怪：你可以使用twodim数组。。。但是你也不会想到为员工使用数组，相反，你写代码8次也没有问题？！意思只有你有var1 var2。。。多达8个阵列的尖叫声…嗯。。。我在工作休息，下班后我会试试这个，然后发布我的代码，我会看看我是否能用它来解决这个问题，我只是对如何让每次通过的次数递增有点困惑。也许将它们分配给一个变量，并在每次传递时递增它？比如年龄[t][0]，然后将t声明为int=0并递增。行吗？好吧，我试过了。我收到一个错误，说employee不能解析为变量。我所做的一切似乎都无法解决这个问题。我已经尝试过预先声明变量，但似乎没有任何效果。有什么提示吗？你使用了正确的代码吗？第一个代码片段就是您所需要的@senpaimaster@senpaimaster我想你错过了这一行：

int[]employees=newint[8]
System.out.println("The current age and desired retirement age for Employee #1 is: " + (ages[0][0]) + " and " + (ages[0][1]) + ".");
System.out.println("Employee #1 has to work " + (employee1) + " years before they can retire.");

System.out.println("\nThe current age and desired retirement age for Employee #2 is: " + (ages[1][0]) + " and " + (ages[1][1]) + ".");
System.out.println("Employee #2 has to work " + (employee2) + " years before they can retire.");

System.out.println("\nThe current age and desired retirement age for Employee #3 is: " + (ages[2][0]) + " and " + (ages[2][1]) + ".");
System.out.println("Employee #3 has to work " + (employee3) + " years before they can retire.");

System.out.println("\nThe current age and desired retirement age for Employee #4 is: " + (ages[3][0]) + " and " + (ages[3][1]) + ".");
System.out.println("Employee #4 has to work " + (employee4) + " years before they can retire.");

System.out.println("\nThe current age and desired retirement age for Employee #5 is: " + (ages[4][0]) + " and " + (ages[4][1]) + ".");
System.out.println("Employee #5 has to work " + (employee5) + " years before they can retire.");

System.out.println("\nThe current age and desired retirement age for Employee #6 is: " + (ages[5][0]) + " and " + (ages[5][1]) + ".");
System.out.println("Employee #6 has to work " + (employee6) + " years before they can retire.");

System.out.println("\nThe current age and desired retirement age for Employee #7 is: " + (ages[6][0]) + " and " + (ages[6][1]) + ".");
System.out.println("Employee #7 has to work " + (employee7) + " years before they can retire.");

System.out.println("\nThe current age and desired retirement age for Employee #8 is: " + (ages[7][0]) + " and " + (ages[7][1]) + ".");
System.out.println("Employee #8 has to work " + (employee8) + " years before they can retire.");

for (int i = 0 ; i < employees.length ; i++) {
    System.out.println("The current age and desired retirement age for Employee #" + (i + 1) + " is: " + (ages[i][0]) + " and " + (ages[i][1]) + ".");
    System.out.println("Employee #" + (i + 1) + " has to work " + (employees[i]) + " years before they can retire.");
