I am not sure what is wrong with my RandomArray method, i want it to work for 2-dimensional arrays but i have clearly made a mistake as the line below is receiving an error and I am unsure as to why this is happening. If you could explain to me the error that I have made i would be grateful.
double[][] g = {RandomArray(3)};
remove the curly brace around the function Call of "RandomArray"
public static void main (String args[]){
double[][] g = RandomArray(3);
printArray(g);
}
private static void printArray(double[][] g) {
System.out.println(Arrays.deepToString(g));
}
public static double[][] RandomArray(int n) {
double[] [] RandomArray = new double[n] [n];
Random randomNumberCreator = new Random();
for (int i = 0; i < n; i++) {
for (int j = 0; j < n; j++) {
RandomArray[i][j] = randomNumberCreator.nextDouble() * 100;
}
}
return RandomArray;
}
You are initializing the array incorrectly.... you dont need the { } when calling the method RandomArray
just doing double[][] g = RandomArray(3);
will do the job
