Java:如何用另一个数组设置一个数组? [英] Java: How to set an array with another array?

问题描述

我对Java还是很陌生，希望您能提出意见.

I'm very new to Java, and I would like your inputs.

所以，我有一个数组:

String[] names = {"Anna", "Jo"};
String[] newNames = {"Bob", "Sue", "Jane"};
int totalLength = names.length + newNames.length;
String[] allNames = new String[totalLength];

我通过以下方式将它们组合在一起:

And I am combining them through:

for (int i = 0; i < names.length; i++) {
    allNames[i] = names[i];
}
for (int i = 0; i < newNames.length; i++}
    allNames[i + names.length] = newNames[i];
}

我的问题是如何将allNames数组设置为原始名称数组?像是"Anna"，"Jo"，"Bob"，"Sue"，"Jane".我知道有些方法可以做到这一点，但是您将如何手动进行呢?

My question is how do I set the allNames array into the original names array? Like, names would be "Anna", "Jo", "Bob", "Sue", "Jane". I know that there are methods that can do this, but how would you do it manually?

推荐答案

第一个首选方法是:

name = (String[])ArrayUtils.addAll(names, newNames);

第二个可能就是您正在做的事情，只需添加:

second one could be what you are doing just add:

name = newName;

在 for 循环之后
