Java List和Array之间的转换
import java.util.Arrays;import java.util.List;
class Test {
//Object数组向List的转换
public static List<String> testArray2List(String[] args) {
return Arrays.asList(args);
}
public static String[] testList2Array(List<String> args){
List<String> list2 = Arrays.asList("aaa", "bbb", "ccc");
String[] array = list2.toArray(new String[list2.size()]);
System.out.println(array);
for (String s : array){
System.out.println(s);
}
return args.toArray(new String[args.size()]);
}
public static void main(String[] args) {
List<String> list1 = Test.testArray2List(new String[]{"aaa", "bbb", "ccc"});
System.out.println(list1);
}
}
输出
[aaa, bbb, ccc]
