50. Write a value-returning method that returns the product of all the elements in an integer array.

public class ArrayProduct { public static void main( String [] args ) { int [] intArray = { 1, 2, 3, 4, 5, 6 }; System.out.print( "The elements are " ); for ( int i = 0; i < intArray.length; i++ ) System.out.print( intArray[i] + " " ); System.out.println( ); System.out.println( "The product of all elements in the array is " + arrayProduct( intArray ) ); } // Insert your code below

51. Write a void method that sets to 0 all the elements of an integer array.

public class ZeroArrayElements { public static void main( String [] args ) { int [] intArray = { 1, 2, 3, 4, 5, 6 }; System.out.print( "The elements are " ); for ( int i = 0; i < intArray.length; i++ ) System.out.print( intArray[i] + " " ); System.out.println( ); System.out.println( "Calling zeroArray method" ); zeroArray( intArray ); System.out.print( "The elements are " ); for ( int i = 0; i < intArray.length; i++ ) System.out.print( intArray[i] + " " ); System.out.println( ); } // Insert your code below }
