Java Enhanced for loop

Question

I applied enhanced for loop on a 2d array. I am getting unexpected output. Please check the code

public class pr {
public static void main(String[] args) {

int listoflist[][]= {{45,34,23},{43,2}};
for (int[] j:listoflist)
{
// System.out.println(j[0]);
for (int k:j)
{
System.out.print(' '+ k);
}
System.out.println();
}

}
}

Answer 1

Use double quote for string. In your code you used single quotes which represents a char. A space (' ' character) has a value 32, and this value is added to each of your array elements on each inner loop iteration.

System.out.print(" " + k);
// double quotes rather than single quotes
