问题描述
我想知道为什么您要使用else if语句，而不要使用多个if语句?例如，这样做有什么区别?
I was wondering why you would use an else if statement, and not multiple if statements? For example, what's the difference between doing this:
if(i == 0) ...
else if(i == 1) ...
else if(i == 2) ...
这:
if(i == 0) ...
if(i == 1) ...
if(i == 2) ...
他们似乎做的完全一样.
They seem to do the exact same thing.
推荐答案
if(i == 0) ... //if i = 0 this will work and skip the following else-if statements
else if(i == 1) ...//if i not equal to 0 and if i = 1 this will work and skip the following else-if statement
else if(i == 2) ...// if i not equal to 0 or 1 and if i = 2 the statement will execute
if(i == 0) ...//if i = 0 this will work and check the following conditions also
if(i == 1) ...//regardless of the i == 0 check, this if condition is checked
if(i == 2) ...//regardless of the i == 0 and i == 1 check, this if condition is checked
