question: public void testConstructorBytesPositive2 ( ) { byte aBytes [ ] = { 12 , 56 , 100 } ; byte rBytes [ ] = { 12 , 56 , 100 } ; BigInteger aNumber = new BigInteger ( aBytes ) ; byte resBytes [ ] = new byte [ rBytes . length ] ; resBytes = aNumber . toByteArray ( ) ; for ( int i = 0 ; i < resBytes . length ; i ++ ) { assertTrue ( resBytes [ i ] == rBytes [ i ] ) ; } assertEquals ( "incorrect sign" , 1 , aNumber . signum ( ) ) ; }
target:  Create a positive number from an array of bytes. The number fits in an integer.
