I have a String array:
String[][] array = new String[7][6];
And I want to auto-fill everything with "[]", with one loop to basically set a default value. I tried to use Arrays.fill but it didn't work out well.

Anything wrong with using two nested loops?Tim Biegeleisen– Tim Biegeleisen2016-02-15 00:57:39 +00:00Commented Feb 15, 2016 at 0:57

I dont know how to set the condition for the max. lenght of the loop in a multidimensional array and then actually set the value to "[ ]".Dean J.– Dean J.2016-02-15 01:08:57 +00:00Commented Feb 15, 2016 at 1:08

Arrays.asList(array).forEach(a->Arrays.fill(a,"[]"));

That one looks pretty good, thanks. Could you maybe explain what that forEach exactly do?
This will work for you if you want it in one loop.
String[][] myArray = new String[7][6];
int i, j;
for(i=0; i<7; i++)
{
j=i;
myArray[i] [j]= " ";
j++;
myArray[i] [j]= " ";
j++;
myArray[i] [j]= " ";
j++;
myArray[i] [j]= " ";
j++;
myArray[i] [j]= " ";
j++;
myArray[i] [j]= " ";
}
