Yes. There is no question about integers.
if
Statements
There are many ways to use
the if
statement.
The statement can be used with one or two
branches, and a branch can have include one
or more statements.
The table that shows these variations.
The booleanExpression
in
each of these varieties evaluates to
true or false.
Boolean expressions come in a variety of forms,
which allow you to carefully state the conditions
under which each branch will execute (see the next
chapter for this.)
Varieties of if Statements | |
---|---|
if ( booleanExpression ) statement; |
if ( booleanExpression ) { one or more statements } |
if ( booleanExpression ) statement; else statement; |
if ( booleanExpression ) { one or more statements } else { one or more statements } |
if ( booleanExpression ) statement; else { one or more statements } |
if ( booleanExpression ) { one or more statements } else statement; |
The style of indenting used here leads to fewer errors than other styles you may have seen. An experiment with a group of professional programmers showed this to be true. Of course, the Java compiler ignores indenting and blank lines. Use this style unless there is a good reason not to (such as an employer that requires a different style.)
No matter which style you use, be consistent. Soon you will be able to visually see the logic of your programs. Programming and error catching will be easier.
