This code always returns false. What might be the problem ?
public class S18_Palindrome {
public static void main(String[] args) {
String myString = new String("malayalam");
if (myString.equals(new StringBuilder(myString).reverse())) {
System.out.println("true");
} else {
System.out.println("false");
}
}
}
问题是StringBuilder(myString).reverse()
将返回您需要从中获取字符串值的StringBuilder
对象。
new StringBuilder(myString).reverse().toString()
Got it :)
I had to convert the StringBuilder's value toString()
if (myString.equals(new StringBuilder(myString).reverse().toString()))
instead of
if (myString.equals(new StringBuilder(myString).reverse()))
Try this..
String s = "responses";
StringBuilder builder = new StringBuilder(s);
System.out.println(builder.reverse());
