如何在java中将向量转换为字符串？ [英] How to convert vector to string in java?

问题描述

我有向量，包含 值5 。当我执行 System.out.Println（vectorVariable）时，输出的值是 [5] 。我想将vectorVariable转换为string（不带[]）。我尝试过 vectorVariable.toString（），它将其转换为字符串，但仍保留[]。所以我想我真正想要的是第一个作为字符串返回的元素。这怎么可能？

I have a vector and it contains the value 5. When i do System.out.Println(vectorVariable), the value outputted is [5]. I want to convert the vectorVariable to string (without the []). I have tried vectorVariable.toString(), which converts it to a string but it still retains the []. So i guess i what i really want is the first element to be returned as a string. How is this possible?

我想在不带[]的字符串中存储向量的值。

I want to store the value of the vector inside a string without the [].

推荐答案

尝试 System.out.println（vector.get（0））。您正在尝试打印整个矢量，而这只会打印所选索引，在本例中为0。

Try System.out.println(vector.get(0)). You are trying to print the entire vector, whereas this will only print the selected index, in this case 0.
