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.


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

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

    Hi sir,
    Thanks for providing java concepts with detailed explanation. Here my question is: The range of java byte is -128 to 127. If we given the value like byte b=129; we are getting an error called “possible loss of precision”. But at the same time it allows the below code:
    int a=143;
    byte b=(byte) a;
    How it allows byte range more than 127?
