byte to int Java

After knowing the Java rules of Data Type Casting (Type Conversion), let us cast byte to int. The byte takes 1 byte of memory and int takes 4 bytes of memory. Assignment 1 byte value to 4 bytes is done implicitly by the JVM.

byte –> short –> int –> long –> float –> double

The left-side value can be assigned to any right-side value and is done implicitly. The reverse requires explicit casting.

Example:

       short x = 10;
       int y = x;

       byte x = 10;
       short y = x;

Following program on byte to int explains the syntax of implicit casting in Java.

public class Conversions
{
  public static void main(String args[])
  {
    byte b1 = 10;              // 1 byte  
    int i1 = b1;               //  one byte to int 4 bytes

    System.out.println("byte value: " + b1);             //  prints 10
    System.out.println("Converted int value: " + i1);    //  prints 10
  }
}

1 byte value b1 is assigned to 4 bytes i1 and is type casted implicitly. This is known as implicit casting or widening conversion.
