how to compare Stringbuffer object and String object

Question

how to compare sb and s

StringBuffer sb= new StringBuffer("Hello");
String s= "Hello";

s.equals(sb.toString()) is giving result as false.

Answer 1

Unable to reproduce:

public class Test {
    public static void main(String[] args) {
        StringBuffer sb= new StringBuffer("Hello");
        String s= "Hello";
        System.out.println(s.equals(sb.toString())); // Prints true
    }
}

If you think the two values are really the same, please post a similar short but complete program demonstrating the problem. I suspect you'll find the problem is elsewhere - such as some invisible characters in the string or StringBuffer.

Answer 2

It is definitely returning true for me. As the content of both strings (the String object you created and the String object returned by the StringBuffer toString()) are the same, the equals() method shouldn't return false.
