When we need to execute a set of statements based on a condition then we need to usecontrol flow statements. For example, if a number is greater than zero then we want to print “Positive Number” but if it is less than zero then we want to print “Negative Number”. In this case ...
If the block of code to be executed is just a single statement, you do not need the brackets { } around them, in the if statements. Here is an example: if ( isValid ) System.out.println("it is valid"); else System.out.println("it is not valid"); However, it is good pract...
If you notice both the conditions, then you could realize that they the same. In both conditions, a and b are equal. However, in such programs, the outermost if-statement holds the highest priority. This is the reason why the output of this program would be “a is equal to b”. Now...

(We could also include braces on just one of the two bodies.) double max; if(first > second) max = first; else max = second; I recommend that you include the braces anyway. This saves you trouble later, should you decide to add additional statements into the body of the statement. ...
The driver will ignore the array if the SQL statement is not an INSERT statement, or an SQL statement able to return auto-generated keys (the list of such statements is vendor-specific). Note:This method cannot be called on a PreparedStatement or CallableStatement. Added in 1.4. Java document...

The if-then and if-then-else Statements Theif-thenStatement Theif-thenstatement is the most basic of all the control flow statements. It tells your program to execute a certain section of codeonly ifa particular test evaluates totrue. For example, theBicycleclass could allow the brakes to de...
