See below
Now each call of findMax()
in main()
uses the appropriate method
class ArrayOps { int findMax( int[] x ) { int max = x[0]; for ( int index=0; index <x.length; index++ ) if ( x[index] > max ) max = x[index] ; return max ; } double findMax( double[] x ) { double max = x[0]; for ( int index=0; index <x.length; index++ ) if ( x[index] > max ) max = x[index] ; return max ; } } class ArrayDemo { public static void main ( String[] args ) { ArrayOps operate = new ArrayOps(); int[] arI = { -20, 19, 1, 5, -1, 27, 19, 5 } ; double[] arF = { 2.1, -4.0, 13.2, 21.95, -6.3, 3.28, 6.0, 0.5 } ; System.out.println("The first maximum is: " + operate.findMax( arI ) ); System.out.println("The second maximum is: " + operate.findMax( arF ) ); } }
(Review Question:) The findMax(int[] x)
method uses a
parameter that refers to an object.
Can parameters also be primitive types, like int
?
