After knowing primitive data types and Java rules of Data Type Casting (Type Conversion), let us cast long to short as an example. The long takes 8 bytes of memory and short takes 2 bytes of memory. Assigning 8 bytes of memory to 2 bytes of memory requires explicit casting. It is like not possible …
After knowing primitive data types and Java rules of Data Type Casting (Type Conversion), let us cast long to byte as an example. The byte takes 1 byte of memory and long takes 8 bytes of memory. Assigning 8 bytes of memory to 1 byte of memory requires explicit casting. This is known as narrowing …
After knowing primitive data types and Java rules of Data Type Casting (Type Conversion), let us cast long to float as an example. A float carries a mantissa part (value of decimal point) where as long takes a whole number. Assignment of long to float is done implicitly. Observe the following order of data types. …
After knowing primitive data types and Java rules of Data Type Casting (Type Conversion), let us cast long to double as an example. The long and double, each takes 8 bytes of memory. The long holds a whole number and double holds a floating-point number. Assignment of long to double is done implicitly by JVM. …
After knowing primitive data types and Java rules of Data Type Casting (Type Conversion), let us cast long to int. The long takes 8 bytes of memory and int take 4 bytes of memory. Assigning 8 bytes of memory to 4 bytes of memory requires explicit casting. byte –> short –> int –> long –> …
A data type informs the compiler what type of data a variable is permitted to store. Data type declaration should be done when the variable is declared. It is required in Java as Java is a strongly typed language. The data type indicates what possible values that can be assigned to variable and possible operations …
