求教 string数组 算一维数组还是二维数组

Question

如题 string数组 算一维数组还是二维数组String[] st = {"abcde","fghij","klmno","pqrst"};请问哪里有错 得到st[2]里面的其中一个字符怎么得到 谢谢

Answer 1

这个是一维数组。public class AnsewerTest
{
public static void main(String[] args)
{
String[] st = {"abcde","fghij","klmno","pqrst"};
for(int i=0;i<st[2].length();i++)
{
System.out.println(st[2].charAt(i));
}
}
}

Answer 2

public static void main(String[] args)
{
String[] st = {"abcde","fghij","klmno","pqrst"};
System.out.println(st[2].charAt(0));
System.out.println(st[2].charAt(1));
System.out.println(st[2].charAt(2));
System.out.println(st[2].charAt(3));
System.out.println(st[2].charAt(4));
}
