extracted from my code.When I compile in terminal I receive "incompatible types: possible lossy conversion from double to int. I am trying to print out a double[][] as a matrix.
I am required to use afor each loop I know that the indexes have to be ints but how would I make sure they are when i can 't convert doubles to ints?
You can do it like this:
// first iterate each row
for (double[] rows : array) {
// then for that row, print each value.
for (double v : rows) {
System.out.print(v + " ");
}
// print new line after each row
System.out.println();
}
For
double[][] a = new double[][] { { 1,2,3 }, {4,5,6 }, { 7,8,9 } };
Prints
1.0 2.0 3.0
4.0 5.0 6.0
7.0 8.0 9.0
