Sure.
Here is the program again, this time with a method that zeros all the elements in the array that the parameter points to.
// Array Example // class ChangeArray { public void print ( int[] x ) { for ( int j=0; j < x.length; j++ ) System.out.print( x[j] + " " ); System.out.println( ); } public void zeroElt ( int[] x, int elt ) { if ( elt < x.length ) x[ elt ] = 0; } // Make all the elements zero. public void zeroAll ( int[] ar ) { } } public class ChangeTest { public static void main ( String[] args ) { ChangeArray cng = new ChangeArray(); int[] value = {27, 19, 34, 5, 12} ; System.out.println( "Before:" ); cng.print( value ); cng.zeroAll( value ); System.out.println( "After:" ); cng.print( value ); } }
Think of what statements should go into the method so that it zeros all elements.
