Row-major order
Also called: row by row
Course: AP® Computer Science A Shows up in: Unit 4: Data Collections
A 2D array traversal that moves across each row, left to right, before going down to the next row.
Appears in the course and exam description (CED): 4.12.A.1
In row-major order the outer loop chooses a row and the inner loop visits every column of that row. A nested enhanced for loop always traverses a 2D array in row-major order.
Example
for (int r = 0; r < grid.length; r++)
{
for (int c = 0; c < grid[0].length; c++)
{
System.out.print(grid[r][c] + " ");
}
}
