I need help getting random numbers between one and ten using a seed, and then putting them into a 2D array. The numbers must go out two decimal places. Here is an example of what the output must look like:
Please enter the grid size: 3
Please enter the random number seed: 4
7.31 9.19 9.19
6.80 0.78 0.25
6.99 8.05 1.51
Column min values:
6.80 0.78 0.25
Row min values:
7.31
0.25
1.51
Diagonal min value: 0.78
Here is the code I have so far. I know it isn't much.
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.print("Please enter the grid size: ");
int size = input.nextInt();
System.out.print("Please enter the random number seed: ");
double[][] array = new double[size][size];
System.out.println();
getArray(array);
printArray(array);
}
public static void getArray(double[][] a){
Scanner input = new Scanner(System.in);
int seed = input.nextInt();
Random random = new Random(seed);
for(int i=0; i<a.length; i++){
for(int j=0; j<a[i].length; j++){
a[i][j] = random.nextDouble() * 10;
}
}
}
public static void printArray(double[][] a){
for(int i=0; i<a.length; i++){
for(int j=0; j<a[i].length; j++){
System.out.print(a[i][j] + " ");
}
System.out.println();
}
}
}
This is my output:
Please enter the grid size: 3
Please enter the random number seed:
1
7.308781907032909 4.100808114922017 2.077148413097171
3.3271705595951118 9.677559094241207 0.061171822657613006
9.637047970232077 9.398653887819098 9.471949176631938
Thank you so much for the help. If you could give me a few pointers on the finding the min values, that would help so much, too.
