Learn about the eight primitive data types in Java, such as byte, int, float, double, boolean and char. See examples, sizes, descriptions and exercises on W3Schools.
Learn about the eight primitive data types (boolean, char, byte, short, int, long, float, double) and the non-primitive data types (classes, interfaces, arrays) in Java. See the default values, sizes, ranges, and examples of each data type.
- 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.
Learn about the eight primitive data types supported by the Java programming language, their ranges, default values, and how to use them in your code. See examples of literals, arithmetic operations, and conversions for each data type.
