x.compareTo(y)should be zero exactly whenx.equals(y). Most classes in the Java API that implementComparablefollow this advice. A notable exception isBigDecimal. Considerx = new BigDecimal("1.0")andy = new BigDecimal("1.00"). Thenx.equals(y)isfalsebecause...

In the program shown in Listing 6.9, we use proxy objects to trace a binary search. We fill an array with proxies to the integers1 . . . 1000. Then we invoke thebinarySearchmethod of theArraysclass to search for a random integer in the array. Finally, we print the matching element. O...

A regular inner class is a nested class that only exists within an instance of enclosing class. In other words, you cannot instantiate an object of an inner class without first having an object of the outer class. An inner class can use all the methods a
