Hello

I am designing a simple program where a user can enter a word or phrase and the program determines if it is a palindrome. A palindrome is a word or phrase that is spelled the same both forwards and backwards...

This is the compile error:

Palindrome.java:165: cannot resolve symbol
symbol : class About
location: class Palindrome
new About(this).setVisible(true);


And here is my code:


Appreciate any help....

Have you defined a class named About in the same package as the Palindrome class? The compiler error is telling you that it does not know the definition of the symbol "About." As you're using it, it should be a class that extends a JComponent of some sort, like Palindrome does (JFrame is a JComponent I believe).
