Size= 4 bytes. long - It is a numeric data type. Size= 8 bytes. float - It is a fractional data type. Size= 4 bytes. double - It is a fractional data type. Size= 8 bytes. Here are some details about non-primitive data types. String - Including characters, spaces and numbers. Array - It is a data structure that can store a group of elements.
