Question

java中怎么把字符串转化为字符串数组？

Answer 1

String string = "abcdsfkk;l";
char[] chars = string.toCharArray();

Answer 2

如果是有分隔符的那种例如"a,b,c";就直接分割就行了.
String string = "a,b,c";
String [] stringArr= string.split(","); //注意分隔符是需要转译滴...
如果是"abc"这种字符串,就直接
String string = "abc" ;
char [] stringArr = string.toCharArray(); //注意返回值是char数组
如果要返回byte数组就直接使用getBytes方法就ok了~~
String string = "abc" ;
byte [] stringArr = string.getBytes();

Answer 3

java有api可以做到，以下是程序和运行结果。

方法介绍如下：   

  /**

     * Converts this string to a new character array.

     *

     * @return  a newly allocated character array whose length is the length

     *          of this string and whose contents are initialized to contain

     *          the character sequence represented by this string.

     */

    public char[] toCharArray() {

    char result[] = new char[count];

    getChars(0, count, result, 0);

    return result;

    }

Answer 4

String str = "123456";
char[] s = str.toCharArray();
for(char val : s){
System.out.println(val);

}

Answer 5

String s = "abc";
String[] split = s.split("");
