How do you convert a String to an Int in Ready To Program with Java?
I need to convert numbers in a string to numbers in an int.
For example:
String x;
x = "123";
needs to be changed to
x = 123;
NOTE: I have to convert a String array into an int.
And the string has commas in it (such as: 1,000,000)

String str = "1234"
int num = Integer.parseInt(str);

You need to process the string as you are specifying that the number may have commas.
However, do check NumberFormat class methods

"NOTE: I have to convert a String array into an int."
No problem. Use a loop.
int[] myInts = new int[myStrings.length];
for (int i = 0; i < myStrings.length; i++)
{
myInts[i] = Integer.parseInt(myStrings[i]);
}
