Syntax:
if (boolean expression)
statement
if (boolean expression)
statement
else
statement
(The expression must evaluate to a boolean.)
Example:
if ((x == y) && (z >= 3))
{
r = 23.0F;
z--;
}
else if (x > y)
{
r = -4.0F;
x++;
}
else r = 10.2F;
Notice that else if is two words. Some languages have a single keyword elseif, but not Java.
