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,两种形式不同,输出的字节码就不同。

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."...
