In Java, if statement is used for testing the conditions. The condition matches the statement it returns true else it returns false. There are four types of If statement they are: 在Java中,if语句用于测试条件。 条件与返回true的语句匹配,否则返回false。 有四种类型的If语句: For example, if we...
Here, the condition number > 5 evaluates to false because number is 3. Therefore, the else block is executed, and the message "The number is not greater than 5." is printed.Example 3: if-else if-else Statementpublic class IfElseIfElseExample { public static void main(String[] args) {...
The next condition, in the else if statement, is also false, so we move on to the else condition since condition1 and condition2 is both false - and print to the screen "Good evening".However, if the time was 14, our program would print "Good day."Exercise? The else if statement ...
Java if-else statements help the program execute the blocks of code only if the specified test condition evaluates to either true or false.
In this tutorial, you'll learn how to use the Java if else statement to execute a code block if a condition is true and another code block otherwise.
if (condition1){ price = 1; } else if (condition2) { price = 2; }else { price = 0; } 优化后 int price = condition1 ? 1 : (condition2 ? 2 : 0); 3、使用Optional 我们在代码中判null会导致存在大量的if-else,这个时候我们可以考虑使用Java8的Optional去优化。

For example: if (condition1) { // do something } elseif (condition2) { // do something else } else { // do another thing } In the above code snippet, if condition1 is true, the block of code within the first if statement will execute. If condition1 is false and condition2 is ...
1 : (condition2 ? 2 : 0); 3、使用Optional 我们在代码中判null会导致存在大量的if-else,这个时候我们可以考虑使用Java8的Optional去优化。 优化前 public static void main(String[] args) { String s = handleStr("11"); System.out.println(s); } private static String handleStr(String str){...
