ParseInt

We can use ParseInt,ParseFloat to convert string to any primitive data types.

public class StringtoInt{
public static void main(String[] args) {
  // TODO Auto-generated method stub
  //int to string
  //String to integer
  
  String abc="This is a string";
  System.out.println(abc);
  Byte xyz=10;
  Byte.toString(xyz);
  
  int x=100,y=200;
  String z=Integer.toString(x);//Int to String conversion
  String l=Integer.toString(y);
  System.out.println(z+l);
  int a=Integer.parseInt(z);//String to Int conversion
  int b=Integer.parseInt(l);
  System.out.println(a+b);
 }
}

output is 
100200
300

In the above program we convert int to string with toString method and then again convert string to int with parseInt method. >>>
