在每个周期的for循环中更改变量的名称（Java）

Ok so I need the variable "value" to have a different name every time the cycle repeats. I am fairly new to java so I am unsure how to go about this. Thanks for the help in advance!

好的,所以每次循环重复时我都需要变量“value”来获得不同的名称。我对java很新,所以我不确定如何解决这个问题。我在这里先向您的帮助表示感谢!

for (int i = 0; i < varOptions.size(); ++i) {
       System.out.print(varOptions.get(i) + ": ");
       double value = myScanner.nextDouble();
}

You can't do that. Maybe you can use value as an array?

你不能这样做。也许你可以使用值作为数组?

double[] value = new double[varOptions.size()];
for (int i = 0; i < varOptions.size(); ++i) {
       System.out.print(varOptions.get(i) + ": ");
       value[i] = myScanner.nextDouble();
}

In array value you will have an array with all input values.

在数组值中,您将拥有一个包含所有输入值的数组。

This is a good place to use an array to store the data:

这是使用数组存储数据的好地方:

double[] someValue = new double[varOptions.size()];
for (int i = 0; i < varOptions.size(); ++i) {
    System.out.print(varOptions.get(i) + ": ");
    someValue[i] = myScanner.nextDouble();
}

After the for loop, someValue, an array of double values, contains all answers

在for循环之后,someValue(一个double值数组)包含所有答案
