A string is one of the most important concepts in Java programming. String
is one of the prebuilt classes in Java. So if you want to manipulate strings, then you could simply create an object of this String
class, and using that object, you can manipulate the string however you want. You can then break the string into two parts, based on the substring
concept. We can also concatenate two strings. All of this can be done with the help of this String
class.
Let's try manipulating a string ourselves. Create a new Java class and name it stringclassdemo
.
One of the most common questions asked in almost all Java related interviews is how a programmer can define strings. The answer is that you can use either of the two following ways:
- By defining the
String
literal - By creating an object of
String
Now let's look at each method, one by one, in order to understand the different ways of declaring a string.
