A class declaration can contain a String instance and methods to set and get its value in Java.
A program that demonstrates this is given as follows:
class Name { private String name; public void setName(String n) { name = n; } public String getName() { return name; } } public class Demo { public static void main(String[] args) { Name n = new Name(); n.setName("John Smith"); System.out.println("The name is: " + n.getName()); } }
The name is: John Smith
Now let us understand the above program.
The Name class is created with a data member name and member functions setName() and getName() that set and get its value respectively. A code snippet which demonstrates this is as follows:
class Name { private String name; public void setName(String n) { name = n; } public String getName() { return name; } }
In the main() method, an object n of class Name is created. Then setName() method is called with string value "John Smith". The name is printed by the calling the method getName(). A code snippet which demonstrates this is as follows:
public class Demo { public static void main(String[] args) { Name n = new Name(); n.setName("John Smith"); System.out.println( "The name is: " + n.getName()); } }
