Computer Science // This is Getter method it can be accessed if you provide the
public “get” and “set” methods. In
public int getYear() {
this case, the get method is used to
return year;
return the value of the variable while
}
the set method is used to set the value,
FOR ONLINE READING ONLY
// This is Setter method
public void setYear(int year) { as shown in Program Example 5.38.
this.year = year; Getter and Setter syntax: They start with
} get or set, followed by variable name.
} The first letter of the variable name
should be written in upper case.
Getter and setter methods: Getter
methods are responsible for fetching Activity 5.11:
the values of private attributes, whereas
setter methods are used to modify Visualisation of encapsulation in
the attribute values. These methods Java
facilitate controlled access to class Use Jeliot 3 or later version,
data and uphold the principle of data visualise the step by step execution
encapsulation. As explained above, of java program to explore about
that private variables can only be encapsulation in Java. Use the code in
accessed within the same class (an Program Example 5.37.
outside class cannot access it). However,

Program Example 5.35:

Java program to demonstrate get and set methods

public class Animal {
private String name; // This shows restricted access

// Getter
public String getName() {
return name;
}

// Setter
public void setName(String newName) {
this.name = newName;
}
}
