CIH, also known as Chernobyl or Spacefiller, is a Microsoft Windows 9x computer virus which first emerged in 1998. It is one of the most damaging viruses, overwriting critical information on infected system drives, and more importantly, in most cases overwriting the system BIOS.
long: The long data type is a 64-bit two's complement integer. The signed long has a minimum value of -263 and a maximum value of 263-1. In Java SE 8 and later, you can use the long data type to represent an unsigned 64-bit long, which has a minimum value of 0 and a maximum value of 264-1. Use this data type when you need a range of values wider than those provided by int.
All these formats are shown in the above example. The Number type can cope with very large (or very small) values and negatives. Very large means up to about 10308, very small means down to about 10-308, if you're mathematically inclined. The String type is for textual characters. There is no type for representing just one character. A String is a row of zero or more characters as a unit, not an array of single characters. Of course, a String of exactly one character is as good as a single character, so that is the way a single character is represented.
