The example below will print the numbers 0 to 4: @assylias: He can use BigInteger too, but that should be obvious, when one reads the API. Primitive number types are divided into two groups: Integer types stores whole numbers, positive or negative (such as 123 or -456), without decimals. Next – let's look at creating a random bounded Long – that is, a Long value within a given range or interval: It takes up 64 bits of memory and accepts a range from -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807.
