Here’s the syntax of the if...then...else statement: if condition then statements; else alternative-statements; end if; The following flowchart illustrates the if else statement. The following example uses an if…then…else statement to display a message showing that a film with a specific ...
An if-statement allways starts with an if. An if-statement can contain zero or many else if, and zero or one else. When else is present, it has to come last, after all the else if. The else statement ensures that one (and only one) of the code blocks will execute....
if后面可以跟一个可选的else块。 如果if测试的布尔表达式求值为false,则执行else块。 以下是语法。 if(boolean_expression) { // statement(s) will execute if the Boolean expression is true } else { // statement(s) will execute if the Boolean expression is false } 流程图(Flowchart) if块保护条件...
The following flowchart represents the nesting of if statements −You can compound the Boolean expressions with && or || to get the same effect. However, for more complex algorithms, where there are different combinations of multiple Boolean expressions, it becomes difficult to form the compound ...

FlowchartThe following flow chart shows how the if...else statement works.The if block guards the conditional expression. The block associated with the if statement is executed if the Boolean expression evaluates to true.The if block may be followed by an optional else statement. The instruction...
The working mechanism of the if-else condition in C++ can be seen in the flowchart shared at the beginning of the article. In the if-else statement, we have two code blocks, either of which is implemented depending on whether the condition is true or false....
2. If…Else Statement in Python The if-else statement runs one block of code if the condition is True and another if the condition does not match and is False. This ensures that the Python programs return some statements. The following flowchart will show you how the If…Else statement in...

在这个图中,METHOD表示 Java 方法,而IF_STATEMENT则表示条件语句。关系线表明一个方法可以包含多个if语句,这进一步强调了它们之间的关系。 总结 了解if语句在 Java 中的作用以及它如何与方法结合是编写高效代码的重要一环。通过上述示例和图表,我们可以清晰地看到,if语句控制着代码的流向,但并不会干扰到整个方法的执行...
