Branching Statements
Table 2-7 (continued)
Assignment Operator Purpose Example
*= Multiplication assignment i *= y (equivalent to i = i * y)
/= Division assignment i /= 3.5 (equivalent to i = i / 35)
%= Modulo assignment i %= 2.8 (equivalent to i = i % 2.8)
Branching Statements
The simplest branching statement is an IF statement that only runs one or
more commands if a Boolean condition is True, such as
if (condition) {
Command;
}
To make the computer choose between two mutually exclusive sets of commands,
you can use an IF-ELSE statement, such as
if (condition) {
Command;
}
else {
Command;
}
Java and C# also offer an IF-ELSEIF statement, which uses two or more
Boolean conditions to choose which of two or more groups of commands to
run, such as
if (condition1) {
Command;
}
else if (condition2) {
Command;
}
Although the IF-ELSE statement can only give the computer a choice of two
groups of commands to run, the IF-ELSEIF statement can offer the computer
multiple groups of commands to run, such as
