- Q2. What is string?
- Ans.
String is a sequence of characters.
In Java, String is a class that represents a sequence of characters.
Strings are immutable, meaning their values cannot be changed once created.
String literals are enclosed in double quotes, e.g. "Hello World".
Strings can be concatenated using the + operator, e.g. "Hello" + "World".
Strings have many built-in methods for manipulation, such as length(), substring(), and indexOf().
- Q3. Write the logic of palindrome?
- Ans.
Palindrome is a word, phrase, number, or other sequence of characters that reads the same backward as forward.
