How to assign a long variable to an output in the previous command in Java?

问题

我是你的中文翻译，以下是翻译好的内容：

我像这样开始了代码：

  1. public static long lcm_of_array_elements(int[] element_array) { 
  2.     long lcm_of_array_elements = 1; 
  3.     ....
  4.     if (counter == element_array.length) { 
  5.         return lcm_of_array_elements;

在我的驱动代码中：

  1. int[] element_array = { a, b, c, d }; 
  2. System.out.println(lcm_of_array_elements(element_array));

在这里，我得到了正确的值，但我想为这个值分配一些变量以执行一些操作。我尝试了以下方法：

  1. long val = lcm_of_array_elements(element_array);

然而，这只返回了最初定义的值：1。所以我尝试了这个，但是它显示了一个错误：

  1. long val = lcm_of_array_elements(element_array).Last.val;

我能否请你提供一个命令来将值存储在某个变量中？

让我们取这些值：a=2,b=3,c=4,d=5

  1. System.out.println(lcm_of_array_elements(element_array)); 
  2. System.out.println(lcm_of_array_elements(element_array)); 
  3. long k = lcm_of_array_elements(element_array);
  4. System.out.println(k);

我的输出是：

  1. 60
  2. 1

但我需要它是：

  1. 60
  2. 60

以下是完整的代码：

  1. // 检查4个数字的最小公倍数是否可被它们的和整除
  2. public static long lcm_of_array_elements(int[] element_array) 
  3. { 
  4.     long lcm_of_array_elements = 1; 
  5.     int divisor = 2; 
  6.     
  7.     while (true) { 
  8.         int counter = 0; 
  9.         boolean divisible = false; 
  10.         
  11.         for (int i = 0; i < element_array.length; i++) { 
  12.             
  13.             if (element_array[i] == 0) { 
  14.                 return 0; 
  15.             } 
  16.             else if (element_array[i] < 0) { 
  17.                 element_array[i] = element_array[i] * (-1); 
  18.             } 
  19.             if (element_array[i] == 1) { 
  20.                 counter++; 
  21.             } 
  22.             
  23.             if (element_array[i] % divisor == 0) { 
  24.                 divisible = true; 
  25.                 element_array[i] = element_array[i] / divisor; 
  26.             } 
  27.         } 
  28.         
  29.         if (divisible) { 
  30.             lcm_of_array_elements = lcm_of_array_elements * divisor; 
  31.         } 
  32.         else { 
  33.             divisor++; 
  34.         } 
  35.         
  36.         if (counter == element_array.length) { 
  37.             return lcm_of_array_elements; 
  38.             
  39.         } 
  40.     } 
  41. } 
  43. // 主驱动代码
  44. public static void main(String[] args) 
  45. { 
  46.     Random rand = new Random();
  47.     int f = 4;
  48.

  56.         System.out.println(c);
  57.         System.out.println(d);
  58.         int e = (a + b + c + d);
  59.         int[] element_array = { a, b, c, d }; 
  60.         System.out.println(e);
  61.         System.out.println(lcm_of_array_elements(element_array));

英文:

I started the code like this and

  1. public static long lcm_of_array_elements(int[] element_array) { 
  2. long lcm_of_array_elements = 1; 
  3. ....
  4. if (counter == element_array.length) { 
  5. return lcm_of_array_elements;

In my driver code:

  1. int[] element_array = { a, b, c, d }; 
  2. System.out.println(lcm_of_array_elements(element_array));

Here, I was getting the right value but I want to assign some variable to this value to perform some operations. I tried the following:

  1. long val=lcm_of_array_elements(element_array) ;

However this only returned the initially defined value : 1.
So I tried, this but it displayed an error:

  1. long val=lcm_of_array_elements(element_array).Last.val ;

Could I please get a command to store the value in some variable?

Let us take values: a=2,b=3,c=4,d=5

  1. System.out.println(lcm_of_array_elements(element_array)); 
  2. System.out.println(lcm_of_array_elements(element_array)); 
  3. long k=lcm_of_array_elements(element_array) ;
  4. System.out.println(k);

My output is:

  1. 60
  2. 1

But I need it to be:

  1. 60
  2. 60

Here is the full code:

  5. int divisor = 2; 
  6. while (true) { 
  7. int counter = 0; 
  8. boolean divisible = false; 
  9. for (int i = 0; i &lt; element_array.length; i++) { 
  10. if (element_array[i] == 0) { 
  11. return 0; 
  12. } 
  13. else if (element_array[i] &lt; 0) {
