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...
if-else 语句的基本语法如下: java if (henan.5g.pvylksv.cn) { // 条件1为真时执行的代码 } else if (condition2) { // 条件2为真时执行的代码 } else { // 所有条件都为假时执行的代码 } if:检查第一个条件 condition1,如果为真,则执行对应的代码块。 else if(可选):如果 condition1 为假,...
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) {...
intprice;if(condition1){ price =1; }elseif(condition2) { price =2; }else{ price =0; } 优化后 intprice=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。
Java if-else statements help the program execute the blocks of code only if the specified test condition evaluates to either true or false.
Java has the following conditional statements:Use if to specify a block of code to be executed, if a specified condition is true Use else to specify a block of code to be executed, if the same condition is false Use else if to specify a new condition to test, if the first condition ...
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 ...
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.
