Two methods are overloaded when they have the same name but different types or numbers of parameters. The compiler will inspect the parameters of a method call and pick the method that best matches the parameter list.
It would be useful to have a method that finds the maximum of an array of double
.
Here is a start on this method;
class ArrayOps { public static 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 ; } public static findMax( ) { max = x[0]; for ( int index=0; index <x.length; index++ ) if ( x[index] > max ) max = x[index] ; return max ; } } public class ArrayDemo { public static void main ( String[] args ) { 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: " + ArrayOps.findMax( arI ) ); System.out.println("The second maximum is: " + ArrayOps.findMax( arF ) ); } }
Fill in the blanks so that the second method call matches the second findMax()
method.
