Trying to set various values into an array using variables and a loop

[monopolyman900]

I'm trying to set values in an array where the user can define the size of the array and inputs each value manually.

My code for setting the values is:

public void createArray()
{
if(arraySize > 0)
{
do{
System.out.println( "Enter number "+ loop2);
array = new int[arraySize];
array[loop] = (int) scan.nextDouble();
loop++;
loop2++;
}
while (loop < arraySize);

However, whenever I print out the results while running the program, the array will always only record the last number that was entered. For example, if I made the array hold 3 values, and I type in 1, 2, and 3, then after each value is entered it will return: 1,0,0, then 0,2,0, then 0,0,3. Anyone know what I'm doing wrong?

The problem is that you are creating/assigning a new int[] instance every time this is being done:

array = new int[arraySize];

Since this snippet is in the do-while loop, every iteration will create a new int[], and assign it to the "array" variable essentially wiping the previous information.

Ah, of course. Thank you, this fixed the problem!
