A computer terminal is not some clunky old television with a typewriter in front of it. It is an interface where the mind and the body can connect with the universe and move bits of it about. Douglas Adams, Mostly Harmless (the fifth volume in The Hitchhiker’s Trilogy) INTRODUCTION This chapter covers simple output to the screen and input from the keyboard, often called console I/O. We have already been using console output, but this chapter covers it in more detail. In particular, this chapter shows you how to format numerical output so that you control such details as the number of digits shown after the decimal point.
If the two strings are equal ignoring case, it returns zero. If the argument is first, it returns a positive number. compareToIgnoreCase(entry) returns a positive number. Some methods for the class String depend on counting positions in the string. Positions are counted starting with 0 not with 1. So, in the string "Surf time", 'S' is in position 0, 'u' is in position 1, and so forth. A position is usually referred to as an index. So, it would be preferable to say: 'S' is at index 0, 'u' is at index 1, and so forth.
The word “equivalent” is in quotes because there is no clear notion of equivalent that applies between any two types. In the case of a type cast from an integer type to a floating-point type, the effect is to add a decimal point and a zero. A type cast in the other direction, from a floating-point type to an integer type, simply deletes the decimal point and all digits after the decimal point. 9 is 2; it is not 3. 0 in the variable d. You cannot store the 5 as the value of d without a type cast, but sometimes Java does the type cast for you.
