Matrix multi dimensional arrays

Question

This code is supposed to display the elements within the array, it works, but I had to use 3 nested for loops. In the instructions for this challenge it says to use 2 nested for loops, can anyone show me how I can do this using 3 nested for loops?

public class Main {
public static void main(String[] args) {
int[][] matrix = {
{8, 1, 6},
{3, 5, 7},
{4, 9, 0},
};
//output the numbers
for (int x = 0; x < 3; x++){

System.out.println(matrix[0][x]);
}

for (int t = 0; t < 3; t++){
System.out.println(matrix[1][t]);
}

for (int q = 0; q < 3; q++){
System.out.println(matrix[2][q]);

}
}
}

Answer 1

Natanael ,

there is also a simplified for loop (for-each loop) that can be used:

Answer 2

public class Main {
public static void main(String[] args) {
int[][] matrix = {
{8, 1, 6},
{3, 5, 7},
{4, 9, 0},
};
//output the numbers
for (int p = 0; p < 3; p++){ //outer loop start

for (int q = 0; q < 3; q++){ //nested inner loop
System.out.print(matrix[p][q]+" ");
} //inner loop ends

System.out.println();
} //outer loop ends..

}
}

//p represents rows
//q represents columns..Natanael

Answer 3

Thank you so much, I thought about rows and columns right before I got your answer

Answer 4

Sorry I meant using 2 nested for loops

Answer 5

I'm thinking these are not nested at all

Answer 6

Thank you, I will try to remember this. The simplified loop is new to me, I think it's more like an abbreviated loop than a simplified loop.
