double numbers[][];
numbers = new double[22][9];
for(int x = 0; x<22; x++) {
for(int y = 0; y <9; y++)
{
numbers[x][y] = (int)(Math.random()*192)+1;
System.out.print(numbers[x][y]+ "");
System.out.println();
}
Trying to display the array within a table/index but when I do, it just display the random numbers vertically. Idk how to fix it. Sorry for the nooby code.. :(
In java two-dimensional array in java is just an array of array, and a small mistake while iterating it. Add System.out.println();
in outer for loop
for(int x = 0; x< 22; x++) { // for every array in outer array
for(int y = 0; y < 9; y++) { //for every double in each inner array
numbers[x][y] = (int)(Math.random()*192)+1;
System.out.print(numbers[x][y]+ " ");
}
System.out.println();
}
If you separate construction and display, it may be clearer:
double numbers[][] = new double[22][9];
// construction
for(int x = 0; x<22; x++)
for(int y = 0; y <9; y++)
numbers[x][y] = (int)(Math.random()*192)+1;
// display
for(int x = 0; x<22; x++){
for(int y = 0; y <9; y++)
System.out.print(numbers[x][y]+ "\t");
System.out.println("");
}
