   • boolean type. The boolean data type has two possible values, either true or false. Default value: false. They are usually used for true/false conditions.
   • byte type. The byte data type can have values from -128 to 127 (8-bit signed two's complement integer). If it's certain that the value of a variable will be within -128 to 127, then it is used instead of int to save memory.
   • short type. The short data type in Java can have values from -32768 to 32767 (16-bit signed two's complement integer). If it's certain that the value of a variable will be within -32768 and 32767, then it is used instead of other integer data types (int, long).
   • int type. The int data type can have values from -231 to 231-1 (32-bit signed two's complement integer). If you are using Java 8 or later, you can use an unsigned 32-bit integer.

   How many data types are there in Java?

   • As explained in the previous chapter, a variable in Java must be a specified data type: Data types are divided into two groups: A primitive data type specifies the size and type of variable values, and it has no additional methods. There are eight primitive data types in Java: Stores fractional numbers. Sufficient for storing 6 to 7 decimal digits

   What is INT data type in Java?

   • The int data type determines that the speed variable can only contain integers. There are 8 data types predefined in Java, known as primitive data types. Note: In addition to primitive data types, there are also referenced types (object type). The boolean data type has two possible values, either true or false.

   Is Java a typed language?

   • Java is a strongly typed language. This means that, in Java, each data type has its own strict definition. There are no implicit data type conversions when any conflicts occur between the data types. Any change in data types should be explicitly declared by the programmer.
