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 the second and third operands have the same type (which may be the null type), then that is the type of the conditional expression. If one of the second and third operands is of primitive type T, and the type of the other is the result of applying boxing conversion (§5.1.7) to...

观察发现if else语句有点类似于三元运算符.其实三元运算符是if else 的一种简写格式. Publicstaticvoidmain(String[] args) {intx = 0, y = 1, b;//if else 语句if(x >y) { b=x; }else{ b=y; } System.out.println(b);//1//3元运算b = x > y ?x : y; ...
} else { if (a > 0) { a = 2; // 这里的body和if (a > 1)的body相同 } } 为了解决这种问题,需要对指令中的 if 语句化简,将这种特殊情况的 if 语句嵌套转为逻辑运算。 break和continue在字节码中表现为goto,会干扰ifbody 的范围识别。

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...
