Java Program to Convert int to String

There are a few ways by using those we can convert int data type to String data type in Java. The most common ways are below:

  1. By using String.valueOf() method.
  2. By using Integer.toString() method.
  3. By using String.format() method.

Now let's see these methods one by one with examples in Java.

Java Program: 

/**

Output: 

Converted String str1 is: 100
5 + int number is: 105
5 + str1 is: 5100
Converted String str2 is: 100
10 + str2 is: 10100
Converted String str3 is: 100
1 + str3 is: 1100
