  ^ ([0- 9]) (?! \ 1 + $) [0-9] + $

काम करना चाहिए

स्पष्टीकरण:

एक अंक से मेल करें और इसे बैक्रेफरेंस में कैप्चर करें # 1: ( [0- 9])
मान लें कि किसी भी लम्बाई (> 1) से मेल खाने वाली एक ही अंक का मिलान करना असंभव है, उसके बाद स्ट्रिंग का अंत: (?! \ 1 + $)

   फिर स्ट्रिंग के अंत तक अंकों के किसी भी स्ट्रिंग से मिलान करें:  [0-9] + $

  संपादित करें: बिल्कुल, जावा में आपको स्ट्रिंग के अंदर बैकस्लैश से बचने की आवश्यकता है ( "\\ ")।
