Convert int to String in Java

In this quick tutorial, I’ll show you how to convert int to String in Java and vice-versa.

Int to String

To convert the int data type to String, we can use the valueOf() method provided in the String class:

public class Demo
{

   public static void main(String[] args)
   {
       // convert int to String
       int number = 5;
       String s = String.valueOf(number);
       System.out.println(s);
   }
}

It is important to note that we can use other primitives with the same method.

String to Int

On the other hand, to convert the String data type to int, we need to perform parsing.

To achieve this, we can use the parse*() methods provided in the wrapper classes:

public class Demo
{

   public static void main(String[] args)
   {  
       // convert String to int
       String s2 = "34";
       int number2 = Integer.parseInt(s2);
       System.out.println(number2);
   }
}
