The eight primitive data types supported by the java programming language are.
These are the types which can hold only a specific set of values for the variables defined using them. C language has some predefined set of data types to handle various kinds of data that we can use in our program. It stores a single character and requires a single byte of memory in almost all compilers. For example, size of int type varies from compiler to compiler, but it. This gives an indication about the amount of memory to be allocated to that variable and each variable will hold its own unique memory location, except for some cases where the variables point to same memory location only.
