void keyword in java
The "void" keyword can be used as the return type of a method to indicate that the method does not return a value.
Example:
- public class Employee
- {
- public void greeting(String name);
- {
- System.out.println("Welcome to "+name);
- // no return
- }
- }
public class Employee
{
public void greeting(String name);
{
System.out.println("Welcome to "+name);
// no return
}
}
We can also specify empty return for void methods as below
- public class Employee
- {
- public void greeting(String name);
- {
- System.out.println("Welcome to "+name);
- return;
- }
- }
public class Employee
{
public void greeting(String name);
{
System.out.println("Welcome to "+name);
return;
}
}
Calling void method should not assign anything as return value
So calling above void method is as below
- Employee e1 - new Employee();
- e1.greeting("Ram");
Employee e1 - new Employee();
e1.greeting("Ram");
Note:
We should use void as the return type of a method when we dont want any return value from the method but only need to execute some code inside a method.
