Arrays

[timack]

Hello everyone,
My problem is I need to let the user enter the dimensions of the array at runtime and use loops to fill the array with random number from 50 to 150. I must the random() method.
Someone please help, I am a beginner! This is what I have so far.

import java.util.Random;

public class ArrayTA
{
public static void main(String [] args)
{
Random random = new Random();

System.out.print("Enter the length of the row: ");
int x = SavitchIn.readLineInt();

System.out.print("Enter the length of the row: ");
int y = SavitchIn.readLineInt();

double [][]myDoubles;
myDoubles = new double [x][y];

for(int i = 0; i<myDoubles.length; i++){
for(int j = 0; j<myDoubles.length; j++){
myDoubles[i][j] = SavitchIn.readLineDouble();}
System.out.println(myDoubles[i]);
}

}
}

I would use a Vector rather than an array...Vectors can be updated dynamically. Check out http://java.sun.com/j2se/1.4.1/docs/...il/Vector.html

Also don't forget that integers are primitives, and not objects. So to add an integer to a vector, you'd have to use vector.addElement(new Integer(...)) rather than vector.addElement(...)
