Characters

The char type is used to represent letters (both uppercase and lowercase), digits, and other symbols. Each character is just a symbol enclosed in single quotes.

char lowerCaseLetter = 'a';
char upperCaseLetter = 'Q';
char number = '1';
char space = ' ';
char dollar = '$';

This type can represent all characters in all languages as well as some special and computer symbols. It corresponds to the Unicode (UTF-16) format. Unicode is a computer encoding methodology that assigns a unique number for every character. It doesn’t matter what language, or computer platform it’s on. This is important in a global, networked world, and for computer systems that must accommodate multiple languages and special characters. Unicode truly unifies all of these into a single standard.

Strings are everywhere in our code, and understanding how to use them effectively is fundamental for any Java developer.

Conditional statement#

The conditional statement is a construction that allows a program to perform different computations depending on the value of a Boolean expression. If it is true, the program performs one computation; otherwise, if it is false, the program performs another computation. Here are some examples of Boolean expressions: a > b, i - j == 1, and so on.

The conditional statement has different forms. We will use all of them.
