The if keyword in Java is a conditional statement that allows you to execute a block of code only if a specified condition evaluates to true. It is one of the fundamental control flow statements in Java, enabling decision-making in your programs.Usage...
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 ...
Yes it does, in spoken english would be something like: DO ask for original price WHILE it is NOT valid, so it will just stop asking once it is valid and everytime the user inputs a double there is the if that changes the boolean to true if it satisfies your condition/validation in ...
The condition can be any Java expression, as long as the result of the expression is a boolean result (either true or false). In the example above, the condition was whether the isValid variable was true or false. If the block of code to be executed is just a single statement, ...
