question: public void testEqualsObject ( ) { byte aBytes [ ] = { 12 , 56 , 100 , - 2 , - 76 , 89 , 45 , 91 , 3 , - 15 , 35 , 26 , 3 , 91 } ; int aSign = 1 ; BigInteger aNumber = new BigInteger ( aSign , aBytes ) ; Object obj = new Object ( ) ; assertFalse ( aNumber . equals ( obj ) ) ; }
target:  equals(Object obj). obj is not a BigInteger
