        String str = "";
        for (i = num - 1 ; i >= 0 ; i--)
            str = str + word.charAt (i);
        if (str.equals (word))
            c.println (word + " is a palindrome");
        else
            c.println (word + " is not a palindrome");




        // Place your program here.  'c' is the output console
    } // main method
} // PalinDrome class

I have created a palindrome program for my exam project. The program works fine with lower cased letters such as "mom" but will not work when there is a capital letter such as "Mom". Do you have any suggestions on what I can do?

使用String#equalsIgnoreCase而不是equals方法，它忽略了大小写考虑。

if (str.equalsIgnoreCase(word)){
  ...
}else
  ...

改变这个

if (str.equals (word))

至

if (str.equalsIgnoreCase(word))

忽略特定情况进行字符串比较。

读取word变量后，修改为小写： word = word.toLowerCase()

其余的可以保持不变，它会工作。

在检查它是否为 Palidrome 之前，只需使用字符串的 toUppercase （或 toLowerCase）
