Shorturlgenerator.java

String Slongurl = "http://www.zuidaima.com/share/1550463378934784.htm"; 3bd768e58042156e54626860e241e999

string[] Aresult = Shorturl (Slongurl);

Print out results

for (int i = 0; i < aresult.length; i++) {

System.out.println ("[" + i + "]:::" + aresult[i]);

}

The console output is as follows: [0]:::7NUFJN [1]:::f6zzy2 [2]:::J6JMQB] [3]:::2eajea
