Java 把字符串转换为字符串数组以及把字符串数组转化为字符串

一：把字符串转换为字符串数组

String content = "aksddjasj";
String array[] = new String[content.length()];
for (int i = 0; i < array.length; i++) {
                array[i] = String.valueOf(content.charAt(i));
            }

二：字符串数组转换为字符串

String array[] = new String[1024];
StringBuilder sb = new StringBuilder();
            for (String ele : array){
                sb.append(ele);
            }
            return  sb.toString();
