Java Variables. Variables are containers for storing data values. In Java, there are different types of variables, for example: String - stores text, such as "Hello". String values are surrounded by double quotes; int - stores integers (whole numbers), without decimals, such as 123 or -123

Java Data Types. Data Types Numbers ... The byte data type can store whole numbers from -128 to 127. This can be used instead of int or other integer types to save memory when you are certain that the value will be within -128 and 127: Example byte myNum = 100; System.out.println(myNum); Try it Yourself » Short.

Java Double Keyword: Your Guide to Decimal PrecisionThe double keyword is used to identify a data type in Java that is used to store decimal numbers, instantiated with the syntax double var = 3.14;. It provides a way to work with numbers that have a decimal point and need a high degree of precision. Here’s a simple example: double num = 10.5; System.out.println(num); # Output: # 10.5.
