Int to String in java  |  Integer to String in java

Being a programmer you will be in a situation where data type conversion is required. So In this article we will look into the must important type conversion that is required maximum time.

Int to String conversion

1. How to convert int to String in java ?

There are two ways to convert int data type into String as

Approach 1 :

String class has static method valueOf(int i), This method in overloaded for all the primitive data types

Prototype of this method is as : 

public static String valueOf(int i)

Sample code :

int number = 10;

String num = String.valueOf(number);

Approach 2:

Integer class has static method toString(int i), This method can also be used to convert int into String

Prototype of this method is as :

public static String toString(int i)

Sample code :

int number = 10;

String num = Integer.toString(rupees);

Note :  In Approach 1, String class valueOf(int i) method internally use Integer class toString(int i) method. So we can say approach one internally use approach two. You can use anyone of them to convert int into String.
