(Java)How can I check if an 2d array contains a certain line? : If given a 2D array, for example int[][] arr = {{2,3}, {53, 2}, {23,13}}; how can i check if the row {53, 2} exist in the array? 
I have the following code:

```
int[][] arr = {{1, 3}, {2, 2}, {2, 5}, {3, 1}, {3, 4}, {3, 7}, {4, 3}, {4, 6}, {5, 2}, {5, 5},
	                 {5, 8}, {6, 4}, {6, 7}, {7, 3}, {7, 6}, {7, 9}, {8, 5}, {8, 8}, {9, 7}};
for(int i = 0; i < 11; i++) {
			for(int j = 0; j < 11; j++) {
				//here i want to check if arr contains the row {i, j}	
				}
			}
		}
```

How can this be done simply and efficiently?
