The "if ... else " Statements
Let's look at situations when the word "otherwise" can be used in your decision making! |
if (test
condition)
{
block of one;
or more Java statements;
}
else
{
block of one;
or more Java statements;
} |
If the test condition is TRUE, the
block of statements following the "if" executes. If the test
condition FALSE, however, the block of statements following the
"else" executes instead. |
 |
If you put a
semicolon after the test condition in an "if - else" combination, an ERROR will occur on the else statement.. |
|
Example:
// example of if ... else
System.out.println("Enter city name: ");
String city = reply.nextLine();
System.out.println("Enter population: ");
int population = reply.nextInt();
if (population >= 543876)
{
System.out.println("According to the census,
" +
city
+ " is one of \n the 100 largest cities.");
}
else
{
System.out.println("According to the census,
" +
city
+ " is not one of \n the 100 largest cities.");
