Question

JAVA怎么样把字符串按每个字符分割成字符串数组

比如 String st = "abcd";
怎么能把他分成 String[] sts = [a,b,c,d];

Answer 1

String test = "aaaasdfs";
String[] arr = new String[test.length()];

for(int i = 0; i < test.length(); i++){
arr[i] = test.substring(i, i+1);
System.out.println(arr[i]);
}

感觉怪怪的

Answer 2

String s="test";char[] ch=s.toCharArray();
String[] sts = new String[ch.length];
for(i=0;i<ch.length;i++)
{
   sts[i] = String.valueOf(ch[i]);
}

Answer 3

st.toCharArray();


st.split("")

追问

st.split("") 取出来第一个是空格啊...char数组不好用..不能比较

追答

char数组可以这样比较啊
String temp = c + "";

String数组，你就从第1个索引开始啊

String str = "1234";
String[] strs = str.split ("");
String[] result = new String[strs.length - 1];
System.arraycopy (strs, 1, result, 0, result.length);
System.out.println (Arrays.toString (result));

Answer 4

split函数
