Two or more methods having same name but different
signatures in the same class or in super class, sub
class(inheritance) then, that method is said to be
overloaded method.
This process is known as method overloading.

Note: Signature of a method means
1) no. of parameters
2) type of the parameter
3) order of the parameters

And a method cant be said as overloaded method only with the
change of the return type alone.

For example,
1) //for no of parameters

void display(int a,int b,int c)
{
System.out.println("This is 3 arguments method");
}

void display(int a,int b)
{
System.out.println("This is 2 arguments method");
}

2) //for type of parameters

void display(int a,int b)
{
System.out.println("This is 2 int arguments method");
}

void display(float a,float b)
{
System.out.println("This is 2 float arguments method");
}

3) //for order of parameters

void display(int a,float b)
{
System.out.println("This is int,float argument method");
}

void display(float a,int b)
{
System.out.println("This is float,int argument method");
}

Note: // cant determine only with return type

void display(int a,int b)
{
System.out.println("This is 2 arguments method without
return type");
}

int display(int a,int b)// compile error here
{
System.out.println("This is 2 arguments method with return
type");
}
