With the help of Integer.parseInt() method, you can convert String to int in Java.
Following is the example that will show conversion from String to int-
public class Example { public static void main(String args[]) { String s = "500"; int i = Integer.parseInt(s); System.out.println(s+200); // + is used as concatenation operator System.out.println(i+200); // + is used as addition operator } }
Output
500200 700
