错误：意外类型，必需：变量并找到：值

Question

I am trying to read in a string using a for loop but its giving me an error. Just checking if current character is "a":

Answer 1

You must use == instead of = .

In Java, we can compare two characters either by using the equals == operator or the equals() method of the Character class.

In your case:

if (inputString.charAt(i) == 'a') {
    ...
}
