Comparison of strings in Java and comparison of Java strings
In C ++, determine whether the values of str_a and str_ B are equal. if (str_a = str_ B) can be used ). However, in Java, if (str_a = str_ B) cannot be used to determine whether the values of str_a and str_ B are equal. "=" Determines whether the storage locations of String str_a and String str_ B are consistent in the memory, rather than whether the values of String str_a and String str_ B are equal. To determine whether the values of str_a and str_ B are equal, use: if (str_a.equals (str_ B ))
