Using Strings?

I basically need to take a string and make an integer equal it. How would I make the integer userInput equal to the string I get from the input.

Code:

int userInput = ???????; //user's input
import javax.swing.JOptionPane;
String lolwut= JOptionPane.showInputDialog(frame, "input");

This is easiest done using the java.util.Scanner class:

Scanner keyboard = new Scanner(System.in); //reacts to whatever someone types
Scanner line = new Scanner( keyboard.nextLine() ); //Makes a scanner of the next line typed in by the user
if( line.hasNextInt() ) // hasNextInt() returns true if the next thing typed in is an int
System.out.println(line.nextInt()); //prints the next int, which is then removed from the scanner

While I don't know how well this works in the Processing interface, this functions perfectly in any java file or other compiler, such as JCreator or JGrasp.

I hope this helps!

Sorry paxromana, but this won't work in Processing, only on the command line.

import javax.swing.JOptionPane;
String lolwut= JOptionPane.showInputDialog(frame, "input");
int x = int(lolwut);
println(x + 1);
