I'm working on an assignment for a class where I first need to declare integer array with 5 rows and 5 columns. Then initialize the array elements to random numbers between one and ten. The output is just a long list of 3 and nothing else. If you could point me in the right direction that would be very much appreciated.
I have to use this statement for random:
int r = (int)(Math.random()*(9-1+1))+1;
This is what I have so far and it's not working:
public static void main(String[] args) {
// TODO Auto-generated method stub
int[][] table= new int [5][5];
int r = (int)(Math.random()*(9-1+1))+1;
for(int row = 0; row < table.length; row++){
for(int column = 0; column < table[row].length; column++){
table[row][column]=r;
System.out.println(table[row][column]);
}
}
}
}
Because you are calculating r before the loop,
int r = (int)(Math.random()*(9-1+1))+1;
all of the numbers in your table are goint to be the same. Move this inside of the loop as such:
for(int row = 0; row < table.length; row++){
for(int column = 0; column < table[row].length; column++){
int r =(int)(Math.random()*(9-1+1))+1;
table[row][column]=r;
System.out.println(table[row][column]);
}
}
(int)(Math.random()*(9-1+1))+1;
could probably be shortened to
(int)(Math.random()*9)+1;
