Java获取随机字符串

- import java.util.Random;
- public static String getRandomString(int length) {
- StringBuffer buffer = new StringBuffer("0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ");
- StringBuffer sb = new StringBuffer();
- Random r = new Random();
- int range = buffer.length();
- for (int i = 0; i < length; i ++) {
- sb.append(buffer.charAt(r.nextInt(range)));
- }
- return sb.toString();
- }
这个没啥意思，就是随机数用的不多，每次要用都记不住，在这里备个份@@
