Integer Data Type Conversion (Java)




The following examples shows you how to convert data between int and other data types i.e., int to string , int to float , float to int etc....

Code

int to String : 

      int a = 10;
       String str = Integer.toString(a);
       System.out.println(str);

Using wrapper class Integer of int data type.
    Integer a = 10;
       String str = a.toString();
       System.out.println(str);

String to int :

Note: String data type can hold integer value as well.

String number = "4321";
       int a = Integer.parseInt(number);
       System.out.println(a);

int to float :

int a = 2;
float f = a;//upcasting from smaller data type to bigger data type
       System.out.println(f);

float to int :

float f = 1.6f;
       int a = (int)f;//but here point value will be lost due to downcasting
       System.out.println(a);
