Yes, i have the following code directly from the book.
package array2d;
public class Array2D {
public static void main(String[] args) {
// TODO Auto-generated method stub
//Basic test
int [][] test1 = new int[4][5];
test1[0][0] = 5;
test1[1][3] = 3;
System.out.println("The row length is " + test1.length);
System.out.println("The colunm length is " + test1[0].length);
//Search using counters
int z = 0;
// int[][] test2 = { { 3, 2, 6, 5 }, { 2, 7, 8, 1 }, { 4, 2, 7, 2 } };
int[][] test2 = { { 3, 2, 6, 5 }, { 2, 7 }, { 4, 2, 7, 2 }, { 7, 9, 2, 1, 6, 5 } };
//Counter search
for (int[] element : test2) {
for (int y = 0; y < element.length; y++ )
{
if(element[y] == 2)
{
z++;
}
}
}
System.out.println("The number 2 was found " + z + " times");
//Enhanced for-loop search
z=0;
for (int x[] : test2)
{
for(int y : x)
{
if (y == 7)
{
z++;
}
}
}
System.out.println("The number 7 was found " + z + " times");
}
}
Under the comment Counter Search the following 4 lines have the word 'element' in them. The original lines after counter search were:
for ( int x = 0; x< test2.length; x++) {
for (int y = 0;y< test2[x].length; y++) {
if ( test2[x][y] == 2) {
z++;
}
}
{
i understand the added lines are a shorter way of doing the double loop but i need the original code to follow the book. If you replace the lines after Counter search with these lines you'll have the original code.
thanks
