I need to generate 10,000 unique identifiers in Java. The identifiers should be a mixture of numbers and letters and less than 10 characters each. Any ideas? Built in libraries would be an extra plus.
解决方案
// class variable
final String lexicon = ABCDEFGHIJKLMOPQRSTUVWXYZ1245674890;
final java.util.Random rand = new java.util.Random();
// cider using a Map to say whether the identifier is being used or not
final Set identifiers = new HashSet();
public String randomIdentifier() {
StringBuilder builder = new StringBuilder();
while(().length() == 0) {
int length = (5)5;
for(int i = 0; i < length; i) {
builder.append(((lexicon.length())));
}
if((())) {
builder = new StringBuilder();
}
}
return ();
}
