How can I give a certain row of elements all the same value? Using a 2d array?

Question

If I have

String[][] trenches = new String[10][10];

How can i make all elements in row 0 have the value of "X" ? or all elements in row 1 have the value of "0" ?

Answer 1

You can do this using a for loop.

int row = 0;
int value = 5;

for(int i = 0; i < trenches[row].length(); i ++)
{
    tenches[row][i] = value;
}

You could put this in a function and pass the row and value

public void standardiseRow(int row, int value)
