Java Data Types Meaning Functionality explained. Every programming language comes with data types. As the name indicates, data type is required to store values (data) in a program. Depending on the nature of value to store, suitable data type should be chosen. For example to store a whole number like 10, 20, choose int data …
After knowing primitive data types and Java rules of Data Type Casting (Type Conversion), let us cast int to short. The int takes 4 bytes of memory and short takes 2 bytes of memory. Assigning 4 bytes of memory to 2 bytes goes by explicit casting where Programmer should do by himself. byte –> short …
After knowing primitive data types and Java rules of Data Type Casting (Type Conversion), let us cast int to float. The int and float, each takes 4 bytes of memory. The int holds a whole number and float holds a floating-point number. Assignment of int to float is done automatically by JVM. byte –> short …
After knowing primitive data types and Java rules of Data Type Casting (Type Conversion), let us cast int to byte. The byte takes 1 byte of memory and int takes 4 bytes of memory. Assigning 4 bytes of memory to 1 byte of memory requires explicit casting. byte –> short –> int –> long –> …
