instance method in java interface static and instance method in java what are instance methods in java
what are instance methods in java with example non static method in java non static method in java with example non static method error in java how static refernece to non-static method in java how we call static method in non-static method in java
Instance Or Non Static Method:
Instance or Non – static method is without the static keyword means that it is
part of an object or it also called "instance" and not a part of a
class. It is referred to by the name of the specific object to which the method
belongs
1) Instance methods are always
recommended to perform repeated time operations.
Such as reading the records
from the files, reading records
2) Instance methods meant for perform
specific operations suitable for individual
programmer.
3) Programmatically instance methods
definition should not preceded by static
keyword.
Syntax:
ReturnType methodname(number of
formal parameters)
{
------------------------ //Block
of statements
------------------------ // Block
of statements
}
4) Each and every instance method is
accessed by object name.
Objectname.Instancemethodname();
The Following Program illustrate the concept of Instance Data
members
Class InsMethodDemo
{
int
x=10; // Instance or non – static data
members
void f1() // Instance or non – static data members
{
System.out.println(“this is f1()
function”+obj.x);
}
public static void main(String args[])
{
{
InstanceDemo obj=new InstanceDemo();
//creation of object or reference for
// Non- static member
obj.f1();
}
}
Analysis:
Above program which illustrate the
concept of Instance data members. For instance data member’s memory will be
created in object or instance and by using that instance we can access the
instance data members.
