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...
The if/else statement is a part of JavaScript's "Conditional" Statements, which are used to perform different actions based on different conditions. In JavaScript we have the following conditional statements: Useifto specify a block of code to be executed, if a specified condition is true ...
在编译ifelse时,如果if条件不成立就会跳转到else部分,我们用’branchX’来表示else部分代码分支开始之处,由于编译器在执行ifelse语句时,IfStatementExecutor先会被执行,当它执行时需要知道当前代码是ifelse还是仅仅包含if语句,如果inIfElseStatement设置成true,那表明当前代码是ifelse形式,如果是false表明当前代码是if形式...
These are simplified examples that show how to use the If-Else statement effectively. Another popular conditional statement used in Java programs is the If-Else If statement. This allows your program to test for more than two choices in a single If-Else statement. In fact, an If-Else If s...

if(condition)//假设条件为真statement1;//if块的一部分statement2;// 与if块分离//如果条件为真if块将语句1视为其一部分,并仅在true条件下执行//语句2将与if块分离,因此无论条件为true还是false,它都将始终执行。 例子: 代码语言:javascript 代码运行次数:0 ...

if(condition)Statement 在此时的条件语句中的条件是需要用括号把它括起来。 其实,Java中的条件语句和C/C++中的是一样的。而Java常常希望在某个条件为真的时候执行多条语句。此时,我们就会引入一个概念,那就是“块模块(block statement)”,具体格式如下,仅供参考: ...
