java - 交错两个字符串数组

Question

在Java中，我有这样的东西:

String[] firstname = { "name1", "name2", "name3" }; 
String[] lastname = { "lastname1", "lastname2", "lastname3" };

我需要的结果是这样的:

String[] newArray = {"name1 lastname1", "name2 lastname2", "name3 lastname3"};

假设长度相同，将姓氏一一组合成String[] newArray。

Answer 1

Java 7 及更早版本的方法可能只是使用循环并迭代所有名字和姓氏:

String[] fullname = new String[firstname.length];
for (int i=0; i < firstname.length; ++i) {
    fullname[i] = firstname[i] + " " + lastname[i];
}
