What is the output from the following program?

public class Modifier {

   public static void modify( int [] array2 ) {

      for ( int counter = 0; counter < array2.length; counter++ )

         array2[ counter ] *= 2;

   }

   public static void modify ( int element ) {

      element *= 2;

   }

   public static void main( String args[] ) {

      int array[] = { 1, 2, 3, 4, 5 };

      modify( array[ array.length – 1 ] );

      System.out.println( “The last array element is “ + array[ array.length - 1 ] );

      modify( array );

      System.out.println( “The last array element is “ + array[ array.length - 1 ] );

   }

}

Explanation / Answer

public class Modifier {
public static void modify( int [] array2 ) {
for ( int counter = 0; counter < array2.length; counter++ )
array2[ counter ] *= 2;
}
  
public static void modify ( int element ) {
element *= 2;
}

public static void main( String args[] ) {
int array[] = { 1, 2, 3, 4, 5 };
modify(array[ array.length-1]);
System.out.println("The last array element is "+ array[ array.length - 1 ] );
modify( array );
System.out.println( "The last array element is " + array[ array.length - 1 ] );
}
}

OUTPUT:

The last array element is 5
The last array element is 10
