    31. října 2023
    11 min
    TV-PG
    There are eight primitive variable types in Java, each of which has a set number of data bits it can hold. Dichone introduces you to the boolean primitive, which can only hold either 1 or 0 (true or false), and the char primitive, which represents one character only.

  10. S1 E10Primitive Variable Types: byte, short, and long

    31. října 2023
    8 min
    TV-PG
    Explore additional primitive variable types. A byte holds eight bits and is commonly used in instances where you need a small container for data. A short holds 16 bits, and makes a great mid-sized container. And a long, at 64 bits, is best for larger numbers.
