Method overloading.

In this article,Method overloading is explained in detail with examples.
Two or more methods in a single class with same name and atleast one difference in the signature is known as method loading.
Signature means a number of arguments, the order of arguments and data type of arguments.
Ex
class A
{
---Data members---;
---Constructors----;
void m1(int,int){---}
void m1(float,float){---}
void m1(int,float){---}
void m1(float,int){---}
}
Total we are using parameterized constructors.

Ex
//program related to Method overloading.
class ExampleClass2
{
void exampleMethod()
{
System.out.println("Method with no arguments");
}
void exampleMethod(int i)
{
System.out.println("Method with 1argument I sis: "+i);
}
void exampleMethod(int i,int j)
{
System.out.println("Method with 2 arguments I is: "+i);
System.out.println("Method with 2 arguments J is: "+j);
}
}
class MethodOverloading
{
public static void main(String args[])
{
ExampleClass2 obj=new ExampleClass2();
obj.exampleMethod();
}
}
Output

Ex
//program related to method overloading.
class ExampleClass2
{
void exampleMethod()
{
System.out.println("Method with no arguments");
}
void exampleMethod(int i)
{
System.out.println("Method with 1argument I sis: "+i);
}
void exampleMethod(int i,int j)
{
System.out.println("Method with 2 arguments I is: "+i);
System.out.println("Method with 2 arguments J is: "+j);
}
}
class MethodOverloading
{
public static void main(String args[])
{
ExampleClass2 obj=new ExampleClass2();
obj.exampleMethod(10);
}
}
Output

Ex
//program related to method overloading.
class ExampleClass2
{
void exampleMethod()
{
System.out.println("Method with no arguments");
}
void exampleMethod(int i)
{
System.out.println("Method with 1argument I sis: "+i);
}
void exampleMethod(int i,int j)
{
System.out.println("Method with 2 arguments I is: "+i);
System.out.println("Method with 2 arguments J is: "+j);
}
}
class MethodOverloading
{
public static void main(String args[])
{
ExampleClass2 obj=new ExampleClass2();
obj.exampleMethod(100,200);
}
}
Output

Ex
//program related to Method overloading.

class Exampleclass2

{

void exampleMethod()

{

System.out.println("Method with no arguments");

}

void exampleMethod(int i)

{

System.out.println("Method with 1 argument I is: "+i);

}

void exampleMethod(int i,int j)

{

System.out.println("Method with 2 arguments I is: "+i);

System.out.println("Method with 2 arguments J is: "+j);

}

void exampleMethod(int i,int j,float k)

{

System.out.println("Method with 3 arguments I is: "+i);

System.out.println("Method with 3 arguments J is: "+j);

System.out.println("Method with 3 arguments k is: "+k);

}

}

class MethodOverloading

{

public static void main(String args[])

{

Exampleclass2 obj=new Exampleclass2();

obj.exampleMethod(100,200,35.87f);

}
